Product overview
An engine coolant thermostat with seal for GM full-size trucks and SUVs, the Cadillac CTS and the Saab 9-7X. It controls coolant flow so the engine warms up quickly and stays at the right temperature. Overheating, a temperature gauge that stays low, weak cabin heat or a check engine light for engine temperature are common signs of a stuck thermostat.
