description

The thermostat is the core temperature control part of engine cooling system. It uses thermal expansion of wax to open and close valve spool and control coolant flow. It runs small cycle for fast warm-up when cold and large cycle for heat dissipation when hot. Failed wax element, stuck valve and damaged sealing gasket lead to slow warm-up, persistent low temperature or overheating alarm, which accelerates component wear and raises fuel consumption.

FAQ 

Q: Will engine never overheat if I remove the thermostat?
A: Not recommended. Engine stays in large circulation and warms up slowly. Continuous low temperature increases wear and fuel consumption.

Q: Can I use a thermostat with different opening temperature?
A: No. Mismatched opening temperature causes low temperature or recurrent overheating. Use OEM spec only.

Q: The thermostat looks intact, how to check if it fails?
A: Do hot water test to verify whether the valve opens at rated
temperature. Appearance cannot confirm wax element status.

Q: What happens if I reuse old gasket while replacing thermostat?
A: Aged gasket tends to leak coolant and leads to overheating due to water shortage. Replace gasket together.
