Coolant Hose, Complete.

The Genuine Porsche Coolant Hose, Complete (95810631022) is an original equipment cooling system replacement component designed for selected Porsche Cayenne 958 models equipped with the 3.0-litre hybrid powertrain.

Fits:

• Porsche 958 Cayenne S V6 3.0L Hybrid (380Hp) 2010-17  

Diagram Ref No 7

Also referred to as a complete water hose or water radiator hose assembly, this component forms part of the vehicle's engine cooling system, carrying coolant between its designated connection points.

The Porsche Cayenne uses a carefully engineered liquid cooling system to regulate operating temperatures and protect the engine during a wide range of driving conditions.

During operation, coolant circulates through the engine and associated cooling system components, absorbing heat and transferring it towards the appropriate heat exchangers.

For the cooling system to perform correctly, coolant must remain contained within a sealed circuit and flow through the correct hoses and passages.

The Porsche complete coolant hose 95810631022 provides one of these connections within the Cayenne's original cooling system arrangement.

Its construction and connection layout are intended to match the relevant factory cooling system specification.

This is important because different Porsche Cayenne engines and production years use different hose configurations.

The coolant hose is continually exposed to high operating temperatures, pressure changes, engine vibration and coolant chemicals.

Over time, these conditions can cause the hose material or its connections to deteriorate.

Ageing hoses may become hard, brittle, swollen or weakened, while damaged connections can allow coolant to escape.

A coolant leak may initially appear as minor dampness around the hose, but continued deterioration can lead to greater coolant loss and potentially compromise engine cooling.

If the cooling system loses too much coolant, the engine may begin to run at an abnormally high temperature.

Severe overheating can damage engine seals, cylinder heads and other internal components.

Replacing a worn or leaking hose with Genuine Porsche part number 95810631022 helps restore the original coolant connection, maintain system integrity and support dependable engine temperature regulation.

This complete hose assembly is particularly suitable for coolant leak repairs, cooling system refurbishment and replacement of deteriorated original pipework.

As a Genuine Porsche part, it provides the specified original equipment replacement for compatible Cayenne cooling system configurations.

What This Product Does:
The coolant hose provides a dedicated passage for coolant circulation within the Porsche Cayenne engine cooling system.

Its main functions include:

• Transfers Engine Coolant: Carries coolant between the relevant cooling system components.
• Maintains Coolant Circulation: Supports uninterrupted flow through the designated cooling circuit.
• Provides a Sealed Connection: Helps prevent coolant escaping from the system.
• Supports Cooling System Pressure: Maintains the integrity of the pressurised coolant circuit.
• Helps Regulate Engine Temperature: Allows coolant to participate in the engine's heat-management process.
