Diagram Ref No 38
Also described as a water hose or engine coolant hose, this component is associated with the engine oil cooler cooling circuit.
The Porsche Cayenne 3.0L V6 diesel engine uses a liquid cooling system to control engine temperature and assist with thermal management of important components, including the engine oil cooling arrangement.
During normal operation, both the engine and its lubricating oil absorb considerable heat.
Coolant circulates through designated passages and heat exchangers to transfer that heat away from the engine and help maintain suitable operating conditions.
The Porsche coolant hose 95810667300 provides a connection within this cooling system arrangement, allowing coolant to travel through the intended circuit.
Although relatively small, the hose is an important part of the sealed cooling system.
Its purpose is to maintain a reliable connection between the associated components while accommodating normal temperature changes, pressure variations and engine vibration.
Modern Porsche diesel engines operate under demanding thermal conditions, particularly during motorway driving, towing, extended journeys and high engine loads.
The cooling system must therefore remain properly sealed and filled to maintain consistent operation.
Over time, coolant hoses can deteriorate through repeated heating and cooling cycles, exposure to engine coolant and general ageing.
Rubber hose material may become hardened, brittle, swollen or cracked.
The hose may also deteriorate around its connections, allowing coolant to escape.
A leaking coolant hose can cause a gradual reduction in coolant level, which may eventually interfere with normal cooling system operation.
If coolant loss becomes significant, the engine may be exposed to overheating and associated mechanical damage.
Replacing a worn or leaking component with Genuine Porsche part number 95810667300 helps restore the original coolant routing and sealed connection.
This hose is suitable for repairs involving coolant leaks, maintenance of the engine oil cooler cooling circuit and replacement of deteriorated coolant pipework.
As a Genuine Porsche component, it is intended to provide the original equipment hose configuration for compatible Cayenne diesel engines.
What This Product Does:
The coolant hose carries liquid coolant between designated components within the engine cooling circuit.
Its primary functions include:
- Transfers Engine Coolant: Provides a passage for coolant to flow through the specified cooling system connection.
- Supports Engine Oil Cooling: Forms part of the coolant arrangement associated with the engine oil cooler.
- Maintains Coolant Circulation: Helps preserve the intended cooling system flow path.
- Provides a Sealed Connection: Prevents coolant from escaping when the hose and associated fittings are in good condition.
- Supports System Pressure Integrity: Helps maintain the closed, pressurised cooling circuit.
- Accommodates Engine Vibration: Provides a connection capable of tolerating normal movement and vibration.
- Supports Temperature Management: Allows coolant to circulate through the cooling components that manage engine and oil temperatures.
- Maintains Factory Routing: Preserves the original coolant connection layout.
- Helps Prevent Coolant Loss: Replaces leaking or deteriorated pipework.
- Supports Engine Reliability: Helps maintain dependable cooling system operation.
Symptoms Of Wear Or Failure:
Coolant hoses operate under conditions involving heat, pressure, vibration and exposure to coolant chemicals.
Although they do not generally have a fixed replacement interval, deterioration can develop with age and mileage.
Typical symptoms:
- Wetness around the coolant hose.
- Coolant dripping from a hose connection.
- Fluid collecting beneath the engine.
- Dried coolant residue around fittings.
- Leaks becoming more noticeable after driving.
- Coolant staining on surrounding components.
- Low coolant warning message.
- Coolant expansion tank level dropping.
- Frequent need to top up the cooling system.
- Coolant warning appearing after longer journeys.
- Coolant smell around the engine compartment.
- Odour becoming stronger after a journey.
- Smell from coolant contacting warm engine components.
- Visible coolant residue around the affected hose.
Why Replacement Matters:
The coolant hose helps maintain the integrity of the engine's cooling system.
A damaged hose may allow coolant to escape, reducing the system's ability to manage heat effectively.
Replacing a defective hose helps restore the original coolant connection and reduce the risk of overheating.
- Helps Prevent Coolant Leaks: Replaces cracked, split or damaged pipework.
- Restores Coolant Circuit Integrity: Maintains a sealed connection within the cooling system.
- Supports Engine Oil Cooling: Preserves the coolant connection associated with the engine oil cooler circuit.
- Maintains Reliable Coolant Flow: Keeps the original routing unobstructed and correctly connected.
- Supports Stable Engine Temperatures: Allows the cooling system to operate as intended.
- Reduces Overheating Risk: Addresses coolant loss before it compromises cooling performance.
- Protects Engine Components: Helps avoid damage associated with inadequate cooling.
- Reduces Breakdown Risk: Replaces a deteriorated hose before a more serious failure.
- Maintains Factory Fitment: Restores the original hose arrangement.
- Genuine Porsche Replacement: Provides the manufacturer's specified replacement for compatible applications.
