So I replaced my electric cooling fan because the motor went bad. I also replaced my thermostat. And now for some reason my heat blows warm not hot like it used to. Also before fan replacement my 04 jeep with the 4.0 used to get to 210 with in like 5 mins of starting it. Now after driving for an hour ill be around 130 150 engine temp. What the hell is happening. I like my engine is running cool but I don't like no heat. Maybe bad temp sensor?
