The oil hose carries engine oil through the thermostat-controlled cooling circuit. The thermostat regulates oil flow to the cooler as temperature changes, while the hose provides a sealed connection between system components.

Functions
• Replaces the oil hose for thermostat
•  Carries engine oil through the thermostat cooling circuit
•  Supports correct oil temperature regulation
•  Helps maintain reliable engine lubrication
•  Helps prevent oil leaks from aged or damaged hoses
•  Suitable for oil line, thermostat, or oil cooling system service
•  OE Match replacement for Porsche 964 oil system repair.

Why Replace This Part?
Oil hoses can harden, crack, swell, corrode at fittings, leak, or become damaged due to age, heat, oil pressure, vibration, and road exposure. A failing thermostat oil hose may cause oil leaks, reduced oil cooling efficiency, low oil level, contamination around the underside of the car, or failed inspection. Replacing the hose helps restore oil system integrity and reliable temperature control.

When to Replace This Part
•  Oil is leaking around the thermostat or oil hose connection
•  The hose is cracked, swollen, hardened, chafed, or damaged
•  Fittings are corroded, seized, or no longer sealing correctly
•  Oil thermostat or oil cooler service is being carried out
•  Oil temperature issues or oil cooling faults are being investigated
•  The vehicle has failed inspection due to oil leakage
•  The car is undergoing Porsche 964 oil system restoration.

Where it fits on the car
This oil hose fits within the thermostat-controlled engine oil cooling circuit on Porsche 964 models. It connects to the thermostat area according to the factory oil line layout.
