Both the upper and lower radiator hoses are the largest hoses in the cooling system connected to the engine.

How do I know if my thermostat housing is leaking?

Signs and Symptoms of a Leaking Thermostat Housing

1. High Readings on Temperature Gauge. With a leaking thermostat housing, the distribution of coolant throughout your engine will be severely compromised.
2. Fluctuating Temperature Readings.
3. Coolant Leaks.

Why is my thermostat housing leaking?

It could be a thermostat gasket leaking if it is coming from the thermostat location. The leaking hose will need to be replaced if the leak is coming from one of the hoses. A cooling system pressure test can reveal the leak location.
