What This Product Does

This hose provides an oil-carrying connection associated with the thermostat in the 964 lubrication circuit. It is a hose replacement, rather than a thermostat assembly. Correct identification requires checking the thermostat reference as well as the vehicle application.

Functions

• Provides a passage for oil within the thermostat-related pipework.
• Supports a sealed connection when correctly matched and installed.

Symptoms of Fault

• Fresh oil beneath the vehicle or dampness along the hose.
• Seepage around connecting unions.
• Visible cracking, deterioration or rubbing damage.
• Oil odour after use, or smoke where escaped oil reaches heated components.
• Leakage appearing after ageing pipework has been disturbed.
  
  

Why Replacement Matters

A deteriorated hose can allow continued oil loss. Renewing a confirmed leaking or damaged component addresses that fault while providing an opportunity to examine adjoining fittings and supporting hardware. Check the source carefully: leakage at a nearby union does not necessarily mean the hose itself has failed.

FAQs

What should be checked before selecting this hose?
Compare the vehicle details, existing hose and thermostat reference. The stated thermostat numbers are an important compatibility condition.

Should nearby fittings also be inspected?
Yes. Examine connections, seals and retaining hardware for deterioration or damage, renewing associated items where required.

How can a repair be checked?
Remove residual oil from the surrounding area and inspect for fresh leakage after operating-temperature cycles.
