Catching radiator problems early is crucial for the health of your engine. A radiator circulates coolant though a series of tubes—as the coolant passes through the engine, it absorbs the heat and later releases it through the radiator. A thermostat regulates the temperature of the coolant in the engine and engages the radiator when a certain temperature is reached. A faulty radiator, leaking radiator hoses and a malfunctioning thermostat may all cause the engine to overheat, which may damage the engine’s components. If the engine temperature warning light comes on, stop the car and contact us right away.
