🔌 Function

The seal holds the thermostat in its cylinder-head recess and forces cooling water to pass through the thermostat rather than around it.

Common signs of failure:

• Engine runs too cold because cooling water bypasses

• Engine overheats because the seal is distorted

• Water leaks around the thermostat assembly

• Seal becomes hard, cracked or compressed

• Thermostat sits loosely in the cylinder head

• Seal is damaged during thermostat replacement
