To install a thermostat on a 1989 Jeep Comanche with a 6-cylinder engine, first, ensure the engine is cool and disconnect the negative battery cable. Remove the radiator hose connected to the thermostat housing and unbolt the housing to access the thermostat. Replace the old thermostat with the new one, ensuring it is oriented correctly with the spring side facing the engine. Reassemble by reattaching the housing and radiator hose, then reconnect the battery and check for leaks.
