Product Overview

The coolant hose, OEM number 94810635505, is the bypass and inlet coolant hose fitted across the Porsche Cayenne, Panamera, and the 911, Cayman, and Boxster, covering 3.6L, 4.5L, and 4.8L engine variants, both turbo and non-turbo, spanning model years 2003-2018. This part has a documented supersession chain (94810635504 to 94810635505 to 94810635506), and because it covers such a wide range of Porsche models and engines, it's a genuinely high-turnover part for anyone stocking Porsche cooling system components.

Worn or failing units typically show up as visible coolant leaks, a sagging or cracked hose under inspection, or engine overheating linked to coolant loss. GSK Auto manufactures this coolant hose to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

(Confirm against your VIN or chassis code before ordering - this hose covers multiple Porsche model lines and both turbo and non-turbo engine variants, so it's worth double-checking the exact chassis and engine configuration before ordering at volume.)

What Is a Coolant Bypass Hose?

Function: The bypass/inlet coolant hose routes coolant through the engine's cooling circuit, feeding coolant to the appropriate components as part of the engine's overall temperature management system.

Working Principle: As the engine runs, coolant is pumped through this hose along its designated path in the cooling circuit, carrying heat away from the engine and helping maintain the correct operating temperature across varying driving conditions.

Importance: A failing hose in the cooling circuit can lead to coolant loss and reduced cooling efficiency, so its condition directly affects the engine's ability to maintain safe operating temperatures.

Common Failures & Signs: Rubber degradation over time causing cracks, softening, or bulging. Visible coolant leaks at the hose or its connection points. Sagging or collapsed hose sections under inspection. Engine overheating linked to coolant loss from a failing hose.
