Product Overview

The coolant hose, OEM number 94810645722, is the engine coolant overflow hose fitted to the Porsche Cayenne and Panamera, 4.8L engine, covering both turbo and non-turbo variants. This part has a documented supersession chain (94810645720 to 94810645721 to 94810645722), and remains a steady part to stock given how many Cayenne and Panamera owners keep these vehicles in long-term service.

Worn or failing units typically show up as visible coolant leaks, a sagging or cracked hose under inspection, or coolant loss requiring frequent top-ups. 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 both turbo and non-turbo 4.8L variants across Cayenne and Panamera, so it's worth double-checking the exact engine configuration before ordering at volume.)

What Is a Coolant Overflow Hose?

Function: The coolant overflow hose feeds coolant back to the overflow or recovery bottle in a closed-loop cooling system, allowing excess coolant and air to be safely managed as the system heats and cools.

Working Principle: As the engine heats up, coolant expands and any excess is directed through this hose to the overflow bottle, where it's stored until the system cools and draws the coolant back in, maintaining consistent coolant volume and pressure in the closed-loop system.

Importance: A failing overflow hose can lead to gradual coolant loss or air entering the cooling system, both of which can affect cooling efficiency and, over time, contribute to overheating if left unaddressed.

Common Failures & Signs: Rubber degradation over time causing cracks, softening, or bulging. Visible coolant leaks at the hose or its connection points. Coolant loss requiring frequent top-ups without an obvious external leak. Air in the cooling system linked to a failing overflow hose connection.
