An engine that runs hotter or cooler than normal, a temperature gauge that behaves oddly, or coolant seeping around the housing can point to a worn thermostat. A weak water pump, a low coolant level, a stuck radiator fan or a faulty coolant temperature sensor can be behind those signs too, so find the cause before buying. The engine takes one thermostat.
