If the engine is not getting to operating temperature replace your thermostat( located at the lower end of the top radiator hose in the water outlet on engine. If the engine IS reaching operating temp, take your hand and feel both heater hoses( they are 1/2"+ hoses that go thru firewall on pass side) both need to be hot; if only one is hot your heater core is plugged and you can flush it. I hope this helps you. Mark
