Thermostat Housing buying guide
Why replace this part?
The thermostat housing holds the thermostat and routes coolant between the engine and radiator. Plastic housings are prone to cracking with heat cycling, causing sudden coolant loss and rapid overheating.
Signs you need a replacement
- Coolant leak at the top of the engine near the thermostat
- rapid coolant loss
- white steam from under the bonnet
- engine temperature swings
- puddles of coolant after the engine warms up
When to replace
No fixed interval — plastic housings typically last 80,000–120,000 miles before cracking. Replace at first sign of leakage.
