Fits:
- Porsche 958 Cayenne S V8 4.2L Diesel (382Hp) 2010-17
Diagram Ref No 18
What This Product Does:
- Transfers coolant between critical cooling system components
- Maintains continuous coolant circulation
- Helps dissipate engine heat through the radiator system
- Supports stable engine operating temperatures
- Prevents overheating by ensuring consistent coolant flow
Symptoms Of Wear Or Failure:
- Coolant leaks under the vehicle or in the engine bay
- Low coolant warning light
- Frequent coolant top-offs
- Engine overheating or rising temperature gauge
- Sweet coolant smell from the engine compartment
- Steam from under the hood in severe cases
- Cracks, splits, or dry rot on the hose surface
- Bulging or swelling due to internal weakening
- Soft, spongy, or brittle hose texture
- Coolant residue or dampness around hose fittings or clamps
- Replacing a worn coolant hose is critical to maintaining proper coolant circulation and preventing engine overheating. Over time, heat, pressure, and coolant exposure can weaken the hose, causing cracks, leaks, or sudden failure.
- If the hose fails, coolant can be lost quickly, leading to overheating and possible serious engine damage such as warped components or head gasket failure. Even minor leaks can reduce cooling efficiency and strain other cooling system parts.
- Installing a new coolant hose helps prevent leaks, restores reliable coolant flow, and protects the engine for long-term performance and durability.

Engine Block Coolant Hoses – Front Engine Porsche Models | Reliable Cooling for Peak Performance
Engine block coolant hoses are critical to maintaining stable engine temperatures and preventing overheating in your Porsche’s front-engine cooling system. These hoses circulate coolant between the engine block, radiator, and heater core, ensuring consistent temperature regulation and efficient heat dissipation — essential for performance, reliability, and longevity.
At Design911, we supply a complete selection of genuine and manufacturer-quality engine block coolant hoses for front-engine Porsche models, including the transaxle models, Cayenne, Panamera, and Macan. Each hose is precisely engineered for a perfect fit and superior heat resistance, offering the same durability, flexibility, and performance as factory-installed components.
What Do Engine Block Coolant Hoses Do?
Coolant hoses in the engine block are responsible for
transferring coolant throughout the engine’s cooling circuit. Their main
functions include:
- Carrying coolant between the radiator, water pump, and engine block.
- Regulating engine temperature for efficient performance.
- Maintaining system pressure within the cooling system.
- Preventing heat build-up that can lead to overheating or gasket failure.
Properly functioning coolant hoses are essential for ensuring your Porsche’s front-mounted engine operates within optimal temperature ranges — especially during heavy use or long drives.
Why Do Engine Block Coolant Hoses Fail?
Due to constant exposure to heat, pressure, and coolant
chemicals, these hoses naturally degrade over time. Common causes of failure
include:
- Heat damage from prolonged exposure to high engine temperatures.
- Rubber deterioration or cracking from age and coolant corrosion.
- Leaks at joints or clamps due to pressure fluctuations.
- Swelling or soft spots from internal chemical breakdown.
- Mechanical abrasion from contact with nearby components.
Symptoms of failing hoses include visible coolant leaks, overheating, low coolant levels, or a strong coolant smell from the engine bay.
Why Replace Faulty Engine Block Coolant Hoses?
A leaking or weakened hose can cause serious cooling system failures, including overheating and engine damage. Replacing old or brittle hoses ensures reliable coolant circulation and safeguards your Porsche’s engine performance.
Benefits of replacement include:
- Restored cooling efficiency and pressure control.
- Prevention of leaks and overheating.
- Improved long-term reliability and system safety.
- Manufacturer-quality materials for perfect fit and heat resistance.
All replacement hoses in this range are constructed using reinforced, high-grade rubber compounds that meet or exceed factory standards, ensuring durability and dependability in all driving conditions.
