Signs of Failure

• Coolant pooling – visible coolant near the housing area

• Low coolant level – recurring need to top up the reservoir

• Temperature warning – engine temperature gauge reading above normal

• Cracked plastic housing – visible cracks or seam separation on the housing body

Critical – Verify Your VIN Before Ordering

Thermostat housings are VIN‑, engine‑, and position‑specific. This is the LOWER outlet connection – it is not interchangeable with the upper connection. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. When replacing the lower thermostat housing, inspect the upper thermostat pipe and all sealing O-rings for wear – these are commonly renewed at the same time. Replace coolant with OEM-specified fluid at the correct mixture ratio after installation and bleed the cooling system thoroughly.
