Engine Coolant Thermostat Kit
This Engine Coolant Thermostat Kit is a complete cooling system service set designed to replace the thermostat and all related components on the Porsche Cayenne 958 3.6L petrol engine (model years 2011 to 2018). It includes OE Match thermostat components, genuine Porsche hardware, seals, gaskets, and sensor - everything required for a professional-grade repair.

Fits:
Porsche 958 Cayenne 3.6L 2011 - 2018

Diagram ref no 8 - 21

This comprehensive kit is engineered to provide a full replacement of the thermostat assembly and associated cooling parts that regulate engine temperature. It includes an OE Match thermostat and thermostat cover, genuine Porsche mounting bolts and seals, an OE Match coolant temperature sensor, adapter and multiple O-rings and gaskets - giving you a complete solution instead of piecemeal parts.

  This kit fits directly in place of the stock thermostat assembly and related parts; no modifications are necessary.  

The thermostat system controls the flow of coolant from the engine to the radiator based on temperature. When the engine is cold, the thermostat remains closed to allow the engine to warm up quickly. As temperature rises, it opens to let coolant pass to the radiator for heat dissipation. This kit ensures consistent and reliable thermo-management, helping your Cayenne reach and maintain optimal operating temperature for performance and emissions control.

Function
A properly functioning thermostat promotes engine efficiency by:
• Enabling rapid warm-up after start
• Preventing overheating during high-load operation
•  Supporting optimal combustion and emissions performance
•  Reducing thermal stress on engine components

The included sensor provides accurate temperature feedback to the vehicle’s ECU, optimizing cooling fan and fuel delivery responses. Genuine seals and O-rings prevent leaks and ensure long-term system integrity.

The thermostat and its associated hardware play a crucial role in relaying correct engine temperature management. A failing thermostat can cause: 
•  Engine to run too cold, hurting fuel economy and emissions
•  Engine to overheat, risking head gasket damage or warped components
•  Erratic temperature gauge behaviour
•  Incorrect fuelling and ignition timing due to poor temp sensor readings

Replacing worn or faulty thermostat components with quality OE Match parts restores reliable engine cooling, protects against overheating, and preserves performance and longevity.

Replace the thermostat kit if you notice:
•  Engine overheating
•  Inconsistent temperature gauge readings
•  Heater core not producing heat
•  Coolant leaks around thermostat housing
•  Failed temperature sensor codes
•  During major cooling system service

What This Product Does:

  • Feeds engine coolant between cooling system components such as the engine, radiator, and expansion/overflow tank.
  • Helps maintain proper coolant circulation, which is essential for controlling engine temperature.
  • Supports overheating prevention by ensuring coolant flows efficiently through the system.
  • Provides a flexible connection that absorbs engine movement and thermal expansion without stressing rigid pipes.

Symptoms Of Wear Or Failure:
  • Coolant may seep or drip from the hose itself or around the hose clamp connection points.
  • A worn feed hose can cause gradual coolant loss, leading to repeated topping up.
  • If the hose leaks or restricts coolant flow, the engine may run hotter than normal.
  • A coolant leak often produces a sweet smell in the engine bay or around the vehicle.
  • Visible signs of deterioration may include cracking, bulging, hardened rubber, wet staining
  • If coolant circulation is affected, cabin heat may become weak or inconsistent.
  • Modern Porsche models may display coolant level or overheating warnings when leaks develop.

Why Replacement Matters:
  • Prevents coolant leaks that can cause low coolant levels and loss of pressure.
  • Helps avoid engine overheating, which can lead to severe and expensive engine damage.
  • Restores proper coolant circulation, ensuring the cooling system performs efficiently under all conditions.
  • Maintains reliable heater performance, since cabin heating depends on correct coolant flow.
  • Protects other cooling components, as leaks can introduce air into the system and increase strain on hoses, seals, and the water pump.

About Engine Block Hoses

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.
