What This Product Does

The hose provides a dedicated coolant passage within the engine cooling circuit. It links the relevant cooling-system components, allowing coolant to circulate while maintaining a sealed connection under normal operating pressure.

Functions

• Routes coolant through its assigned part of the cooling system.
• Connects pipework within the water reservoir assembly.
• Maintains a sealed path for pressurised coolant.
• Replaces a hose affected by age, cracking or leakage.

Technical Details

• Genuine Porsche component.
• Porsche part number: 95810650300.
• Exploded-diagram description: water hose.
• Assembly: water cooling and water reservoir.
• Vehicle equipment codes: PR D50 and D1V.
• Quantity specified in the exploded diagram: 1.

Symptoms of Fault

• Falling coolant level between checks.
• Damp areas or dried coolant deposits around the hose joints.
• A sweet smell from the engine compartment.
• Visible cracking, swelling or hardening of the hose.
• Low-coolant alerts or an abnormal rise in engine temperature.
• Seepage after switching off, when heat soak increases cooling-system pressure.

Why Replacement Matters

A weakened hose can release coolant or permit air to enter the circuit, potentially reducing cooling efficiency and causing overheating. When fitting the replacement, inspect the adjoining clamps, mating connections and nearby hoses for corrosion, residue or deterioration. The cooling system should be refilled and bled using the appropriate procedure.

FAQs

• Can this hose leak only when the engine is hot?
  Yes. Fine splits and weakened connections may only seep once coolant temperature and system pressure increase.
• Should the clamps and connecting points be checked?
  Yes. Examine each mating surface and clamp for damage, deposits or poor sealing before refilling the system.
• Can the coolant reservoir be opened immediately after driving?
  No. Wait until the engine and pressurised cooling system have cooled before removing the reservoir cap.
