Volvo XC90 Thermostat replacement
When do Volvo XC90 thermostats need to be replaced?
A car's thermostat is part of the Volvo XC90's cooling system, the thermostat regulates the engine’s operating temperature and flow of coolant circulation through the engine.
It keeps your Volvo XC90's engine at the optimum running temperature so the engine has time to warm up on startup and also cool down when it is hot.
The thermostat is a valve that opens and closes to allow or deny coolant flow. When a thermostat fails it can get stuck open or closed. This can cause the engine to overheat.
Volvo XC90 thermostats can fail due to a defect, old age, overheating, and sludge buildup. If it does malfunction it can lead to serious problems and should be replaced as soon as an issue is detected.
