An engine that runs hot, takes a long time to warm up, or shows a temperature gauge that stays low can point to a thermostat stuck closed or open. Before you replace the thermostat, rule out a low coolant level (check it only with the engine cool), a leaking hose, or a weak fan or water pump, since those can also cause overheating.
