    Q:
    What should be checked before condemning the thermostat for the 1988 Chevrolet K1500? Posted by Customer
    A:
    Check the coolant level in the system. Verify the drivebelt tension is correct. Observe the temperature gauge or light operation. If the engine takes a long time to warm up, it may indicate a thermostat stuck open and needs replacement. If the engine runs hot, and the upper radiator hose isn't hot, it suggests a thermostat stuck shut and should be replaced. If the upper radiator hose is hot, it indicates that the coolant is circulating and the thermostat is open.
