Diagram Ref No 22
The line carries vacuum through the vehicle to the brake servo / brake booster. This vacuum assistance reduces the amount of pedal effort required from the driver when applying the brakes, allowing the braking system to deliver strong and progressive braking with a normal pedal feel.
Because the line must remain airtight, cracks, damaged connections or leaks can reduce the amount of vacuum available to the brake booster. This can lead to a noticeably harder brake pedal and reduced power assistance, even though the hydraulic brakes may still operate mechanically.
What This Product Does:
- Carries vacuum to the brake booster.
- Supports power-assisted brake operation.
- Reduces the amount of pedal force required during braking.
- Helps maintain a consistent and predictable brake pedal feel.
- Forms part of the sealed brake-servo vacuum circuit.
- Transfers vacuum through the central/underbody section of the vehicle.
- Helps the brake booster provide additional braking assistance.
- Replaces a cracked, damaged, leaking or deteriorated original vacuum line.
- Restores vacuum-system integrity when a leak has been identified.
Porsche parts diagrams list 99735557101 directly within the brake-line and underbody vacuum system, identifying it as the central vacuum line in the brake system.
Symptoms Of Wear Or Failure:
Possible symptoms include:
- Brake pedal becoming unusually hard.
- Increased pedal effort required to slow the vehicle.
- Reduced brake-servo assistance.
- Brakes feeling normal initially but becoming harder after repeated pedal applications.
- Hissing noise when the brake pedal is pressed.
- Hissing or air-leak noise from underneath the vehicle.
- Vacuum-related noises after the engine is switched off.
- Inconsistent brake pedal assistance.
- Cracks or splits in the vacuum line.
- Damaged or loose line connections.
- Physical damage caused by road debris or underbody impact.
- Deteriorated seals or connecting pieces.
- Brake booster failing to retain vacuum.
- Vacuum-system faults found during diagnostic testing.
A hard brake pedal does not automatically mean the vacuum line itself has failed. The brake booster, vacuum pump, non-return valve, connections and other vacuum hoses should also be checked during diagnosis.
Why Replacement Matters:
The brake booster relies on vacuum to provide power assistance.
If the vacuum line develops a leak, the booster may receive insufficient vacuum to assist braking correctly. The hydraulic braking system can still apply the brakes, but substantially greater pedal force may be required.
Replacing a leaking or damaged vacuum line helps restore:
- Correct brake booster vacuum.
- Normal brake pedal effort.
- Consistent braking assistance.
- Predictable brake pedal feel.
- A sealed vacuum circuit.
- Reliable brake-servo operation.
Because this component directly affects brake assistance, confirmed vacuum leaks should be addressed promptly.

Diagram Ref No 21
Despite being described as a breather hose, this component is part of the cooling system rather than the engine crankcase ventilation system. Its purpose is to provide a controlled path for coolant and displaced air within the cooling circuit, helping the system vent correctly and maintain reliable coolant circulation.
As the engine heats and cools, coolant expands and contracts while small amounts of trapped air may move through the system. The vent hose helps manage this movement between cooling-system components so that unwanted air pockets do not interfere with normal coolant flow.
With age, repeated heat cycles and prolonged exposure to coolant, the original hose can harden, crack, split or begin leaking around its connections. Replacing a deteriorated hose helps restore a sealed cooling circuit and reduces the risk of coolant loss or air entering the system.
What This Product Does:
The coolant breather hose forms part of the engine's liquid-cooling system.
It is designed to:
- Provide a vent path within the cooling circuit.
- Help move displaced air through the cooling system.
- Assist with coolant circulation between connected components.
- Help prevent unwanted air pockets forming within the cooling system.
- Maintain a sealed coolant circuit.
- Carry coolant where required during expansion and contraction.
- Support correct operation of the expansion-tank and cooling-system arrangement.
- Replace a cracked, leaking or hardened original hose.
- Help maintain correct coolant level and system pressure.
Symptoms Of Wear Or Failure:
Possible symptoms include:
- Visible coolant leakage.
- Dampness around the hose or its connections.
- Dried coolant residue around fittings.
- Gradual reduction in coolant level.
- Coolant smell around the engine compartment.
- Hose becoming hard or brittle.
- Visible cracking.
- Splits in the hose.
- Swelling or deformation.
- Leakage when the cooling system becomes hot and pressurised.
- Air repeatedly entering the cooling system.
- Coolant-level warning appearing.
- Engine temperature becoming less stable.
- Coolant collecting around nearby components.
- Steam or coolant vapour from the engine area in severe cases.
Similar symptoms can also be caused by the expansion tank, cap, water pump, radiator hoses or other cooling-system components, so the actual source of the leak should be confirmed.
Why Replacement Matters:
The cooling system needs to remain sealed to maintain the correct coolant volume, pressure and circulation.
A leaking vent hose can allow coolant to escape and may permit air to enter the system as the engine cools.
Replacing a damaged hose helps restore:
- A sealed cooling circuit.
- Correct coolant retention.
- Proper cooling-system venting.
- Stable engine temperature.
- Reliable coolant circulation.
- Reduced risk of air pockets.
- Long-term cooling-system reliability.

- Coolant Smell: Escaping coolant may produce a distinctive sweet smell around the affected area.
- Engine Overheating: Substantial coolant loss can reduce the overall cooling system's ability to regulate engine temperature.
- Steam from the Engine Compartment: A significant coolant leak may allow coolant to contact hot components, producing visible steam.
- Loose or Damaged Hose Connections: Corroded clamps or damaged connection surfaces may allow coolant to escape.
Why Replacement Matters:
- Replacing a worn, leaking or damaged heater supply hose is essential for maintaining the reliability, efficiency and integrity of your Porsche's heating and cooling system.
- The heater supply circuit relies on a secure passage for heated engine coolant to circulate between its associated components. If the supply hose becomes cracked, swollen or weakened, coolant may escape, reducing the system's ability to maintain correct coolant levels and pressure.
- Even a small coolant leak can develop into a more serious problem, particularly as the hose undergoes repeated heating and cooling cycles.
- As coolant levels fall, air may enter the system, potentially affecting heater performance and contributing to inconsistent temperature regulation.
- If the hose deteriorates further and fails under pressure, sudden coolant loss may occur. This can increase the risk of engine overheating and potentially lead to costly damage to cylinder heads, gaskets and other critical engine components.
- A correctly fitted Genuine Porsche replacement hose helps restore a secure, leak-resistant connection and maintain the original heating circuit configuration.
- Replacing deteriorated hoses during routine servicing or cooling system repairs can also help prevent unexpected breakdowns and reduce the likelihood of additional damage to surrounding components.
- For high-performance Porsche 997 Turbo, GT2 and GT3 models, maintaining cooling system integrity is particularly important because the engines can experience substantial thermal loads during demanding driving conditions.
- The genuine replacement hose provides the correct factory-style routing and connection arrangement, making it suitable for owners who wish to maintain original equipment quality and compatibility.
- The Genuine Porsche Heater Supply Hose 99710623372 offers an original equipment replacement solution designed to restore reliable coolant circulation, maintain cabin heating performance and help protect the engine against coolant loss and overheating.

The blower motor is essential for effective cabin ventilation, heating, air-conditioning and windscreen demisting. When the motor or blower wheel becomes worn, damaged or electrically defective, cabin airflow can become weak, noisy, intermittent or stop completely.
Replacing a confirmed faulty blower motor helps restore dependable airflow through the HVAC system, improving cabin comfort and maintaining effective windscreen demisting and defrosting.
What This Product Does:
The Blower Motor electrically drives the attached blower wheel, creating the airflow required to move conditioned air through the HVAC system.
Depending on the selected climate-control settings, the blower moves air through the system and distributes it through the vehicle's:
- Dashboard air vents
- Windscreen demister outlets
- Footwell vents
- Cabin ventilation outlets
- Heating system
- Air-conditioning system
The motor's speed is controlled by the vehicle's HVAC electronics, allowing airflow to increase or decrease according to the selected fan setting or automatic climate-control requirements.
Symptoms Of Wear Or Failure:
Common symptoms of blower motor or blower wheel deterioration can include:
- No airflow from the cabin vents
- Weak airflow
- Intermittent airflow
- Fan operating only occasionally
- Fan stopping unexpectedly
- Blower failing to start
- Fan speed fluctuating unexpectedly
- Blower working at some speeds but not others
- Reduced heating performance caused by insufficient airflow
- Reduced air-conditioning effectiveness caused by insufficient airflow
- Slow windscreen demisting
- Poor windscreen defrosting
- Squeaking or squealing noises
- Grinding noises
- Scraping sounds
- Rattling or vibration from the HVAC system
- Excessive vibration through the dashboard
- Burning or overheated electrical smell
- Blower motor electrical faults
- HVAC-related diagnostic fault codes
- Blown fuse or excessive electrical current draw
Not every airflow problem is caused by the blower motor itself. A blocked cabin filter, faulty blower controller/resistor, damaged wiring, electrical connection problems, HVAC control faults or obstructed air ducts can produce similar symptoms.
Why Replacement Matters:
Replacing a confirmed worn or failed Blower Motor helps restore the airflow required for effective operation of the vehicle's HVAC system.
Replacement can help:
- Restore normal cabin airflow
- Restore reliable fan operation
- Improve heating performance
- Improve air-conditioning effectiveness
- Restore effective cabin ventilation
- Improve windscreen demisting
- Improve windscreen defrosting
- Eliminate noise caused by worn motor bearings
- Reduce vibration caused by a damaged blower assembly

As the engine operates, the pump circulates oil through lubrication passages to critical components including:
- Crankshaft bearings
- Connecting-rod bearings
- Camshaft components
- Valvetrain components
- Timing chains and sprockets
- Chain guides and tensioners
- Other moving internal engine surfaces
The drive chain itself does not generate oil pressure. Its function is to mechanically drive the oil pump. The pump and associated lubrication system generate, regulate and distribute the required oil flow and pressure.
Symptoms Of Wear Or Failure:
Possible symptoms of deterioration within the oil pump chain or associated drive system include:
- Metallic rattling or clattering
- Mechanical chain noise
- Rattle during engine start-up
- Noise that changes with engine RPM
- Excessive chain slack
- Chain elongation
- Excessive chain movement
- Visible wear to chain links or pins
- Abnormal drive-sprocket wear
- Worn or damaged chain guides, where fitted
- Excessive tensioner travel, where applicable
- Metal or plastic debris in the engine oil
- Wear debris found in the oil filter
- Oil-pressure warning light
- Low oil-pressure warning
- Oil-pressure-related diagnostic faults
- Increased mechanical engine noise associated with inadequate lubrication
A low oil-pressure warning does not automatically mean the oil pump drive chain has failed.
Why Replacement Matters:
The Oil Pump Drive Chain performs a critical mechanical function within the engine lubrication system.
Replacing a confirmed worn, elongated or damaged drive chain can help:
- Restore reliable oil pump drive
- Maintain dependable engine oil circulation
- Reduce excessive chain slack
- Reduce abnormal mechanical noise
- Restore reliable sprocket engagement
- Protect associated drive sprockets
- Protect chain guides and tensioning components
- Reduce the risk of chain derailment
- Reduce the risk of chain breakage
- Maintain reliable engine lubrication
- Protect crankshaft and connecting-rod bearings
- Protect camshaft and valvetrain components
- Protect associated timing components
- Reduce the risk of lubrication-related engine damage
Because the engine relies on continuous oil circulation, a confirmed fault within the oil pump drive system should not be ignored.

Timing chains operate continuously whenever the engine is running. Although designed for long service life, repeated mechanical loading, friction, heat and lubrication conditions can gradually cause wear to the chain pins, links and contact surfaces. Timing-chain guides, tensioners and sprockets may also deteriorate over time.
As wear increases, the effective length of the chain can increase, resulting in excessive slack, abnormal mechanical noise and potentially inaccurate engine timing. Severe deterioration can increase the risk of the chain jumping, derailing or failing.
What This Product Does:
The Timing Chain transfers mechanical rotation through the engine timing system while maintaining the required synchronisation between associated timing components.
Depending on the specific engine configuration, correct timing-chain operation helps support:
- Accurate engine timing

The oil pump must operate whenever the engine is running to circulate lubricant through the engine. This chain forms part of the mechanical drive system that keeps the pump operating, supporting lubrication of bearings, crankshaft components, camshaft and valvetrain parts, timing components and other moving internal surfaces.
Although designed for extended service life, an oil pump drive chain is subjected to continuous mechanical loading, friction and heat. Wear to the chain links, pins and associated sprockets can gradually increase chain slack and reduce the reliability of the drive system.
What This Product Does:
The oil pump chain transfers mechanical rotation through the engine's oil pump drive system, allowing the oil pump to operate continuously while the engine is running.
Reliable pump operation allows engine oil to circulate to critical components including:
- Crankshaft bearings

- Valvetrain components
- Timing chains and sprockets
- Timing guides and tensioners
- Other internal moving and friction surfaces
The chain itself does not generate engine oil pressure. It provides mechanical drive to the oil pump; the pump and lubrication system are responsible for producing, regulating and distributing the required oil flow and pressure.
Symptoms Of Wear Or Failure:

A low oil-pressure warning does not automatically indicate a failed oil pump chain. Low oil level, oil pump wear, a restricted pickup, pressure-control problems, incorrect oil, excessive bearing clearance or an oil-pressure sensor fault can produce similar symptoms.
Why Replacement Matters:
The Oil Pump Timing Chain performs a critical mechanical function within the engine lubrication system.
Replacing a confirmed worn, elongated or damaged chain can help:
- Restore reliable oil pump drive

As the engine rotates, this mechanical drive allows the oil pump to circulate engine oil through the lubrication system.
Reliable oil circulation supports lubrication of critical components such as:
- Crankshaft bearings
- Connecting-rod bearings
- Camshaft and valvetrain components
- Timing chains and sprockets
- Timing-chain guides and tensioners
- Other internal moving components and friction surfaces
The chain itself does not generate oil pressure. Its purpose is to mechanically drive the oil pump. The pump, pressure-control system and lubrication circuit are responsible for producing and regulating oil flow and pressure.

An oil-pressure warning does not automatically mean the chain has failed. Low oil level, oil pump wear, a blocked pickup, pressure-regulation faults, excessive bearing clearance, incorrect oil or a defective pressure sensor can produce similar symptoms.
Why Replacement Matters:
The Timing Chain performs a critical mechanical role within the engine lubrication system.
Replacing a confirmed worn, elongated or damaged chain can help:
- Restore reliable oil pump drive

The chain transfers rotational drive from the engine to the oil pump, allowing the pump to circulate engine oil through critical lubrication points. Reliable operation is essential because the engine depends on continuous oil circulation to lubricate bearings, crankshaft journals, camshaft components, timing components and other moving internal parts.
Although designed for extended service life, an oil pump drive chain operates continuously whenever the engine is running. Wear to the chain, sprockets, guides or tensioning components can eventually cause excessive slack, abnormal noise or unreliable oil pump drive.
What This Product Does:
The oil pump/crankshaft chain transfers mechanical rotation from the crankshaft drive system to the engine oil pump.
As the engine runs, the chain keeps the oil pump mechanically driven so that it can circulate engine oil throughout the lubrication system.
This supports lubrication of critical components including:
- Crankshaft bearings
- Connecting-rod bearings
- Camshaft components
- Valvetrain components
- Timing-system components
- Other internal moving and friction surfaces
The chain itself does not create oil pressure. Its function is to drive the oil pump; the pump and lubrication system are responsible for generating and maintaining the required oil flow and pressure.
Symptoms Of Wear Or Failure:
Possible symptoms of chain or associated drive-system deterioration include:
- Metallic rattling or clattering from the engine
- Mechanical chain noiseNoise that changes with engine RPM
- Excessive chain slack
- Chain elongation
- Visible wear to chain links or pins
- Abnormal sprocket wear

- Metal or plastic debris in the engine oil
- Debris found in the oil filter
- Oil-pressure warning light
- Low oil-pressure warning message
- Oil-pressure-related diagnostic faults
- Abnormal engine noise caused by inadequate lubrication
A low oil-pressure warning does not automatically mean the drive chain has failed. Low oil level, a worn oil pump, blocked oil passages, pickup problems, incorrect oil, pressure-control faults, bearing wear or an oil-pressure sensor problem can produce similar symptoms.

Diagram Ref No 1
The timing chain transfers rotational drive from the crankshaft through the timing mechanism so that camshaft operation remains correctly synchronised with piston movement. This precise relationship allows the intake and exhaust valves to operate at the correct points during the engine's combustion cycle.
Timing chains are designed for extended service life, but continuous mechanical loading, friction, heat and lubrication conditions can gradually cause wear. Chain elongation, worn guides, defective tensioners or damaged sprockets can create excessive slack and affect timing accuracy.
If deterioration becomes severe enough for the chain to jump, derail or fail, incorrect valve timing and potentially serious internal engine damage can result.
What This Product Does:
The camshaft/crankshaft timing chain provides the mechanical connection required to keep crankshaft rotation and camshaft operation correctly synchronised.
As the crankshaft rotates, the timing drive transfers this movement to the camshaft timing system.
This helps maintain:
- Correct crankshaft-to-camshaft synchronisation
- Accurate valve timing
- Correct intake valve operation
- Correct exhaust valve operation
- Reliable mechanical timing
- Smooth combustion
- Stable engine operation
- Consistent power delivery
Correct timing-chain tension and accurate engagement with the associated sprockets are essential for maintaining this relationship.
Symptoms Of Wear Or Failure:
Possible symptoms of timing-chain or associated timing-system deterioration include:
- Metallic rattling or clattering from the timing area
- Timing-chain rattle during cold starts
- Noise immediately after engine start-up
- Excessive chain slack
- Timing-chain elongation
- Mechanical noise that changes with engine RPM
- Rough or irregular engine operation
- Unstable idle
- Difficult or extended starting
- Reduced engine performance
- Poor throttle response
- Misfires
- Engine warning light
- Timing-related diagnostic fault codes
- Camshaft-position faults
- Crankshaft-position faults
- Crankshaft/camshaft correlation faults
- Variable camshaft timing faults where applicable
- Visible chain wear during inspection
- Worn or broken timing-chain guides
- Excessive tensioner travel
- Abnormal sprocket wear
- Metal or plastic debris in the engine oil or filter
These symptoms can also be caused by guides, tensioners, sprockets, variable timing components, sensors or lubrication problems. Proper diagnosis is therefore important before individual components are replaced.
Why Replacement Matters:
The Timing Chain is a critical component within the engine timing system.
Replacing a confirmed worn, elongated or damaged chain can help:
- Restore accurate crankshaft/camshaft synchronisation
- Maintain correct valve timing
- Restore dependable mechanical timing
- Reduce excessive chain slack
- Reduce abnormal timing-chain noise
- Maintain reliable sprocket engagement
- Protect timing-chain guides
- Protect associated sprockets
- Reduce the risk of timing deviation
- Reduce the risk of the chain jumping
- Reduce the risk of chain derailment
- Support smooth engine operation
- Protect expensive internal engine components
Continuing to operate an engine with a confirmed timing-chain problem can allow wear to progress and substantially increase the cost of the eventual repair.
