My 97' TJ Sport's heater doesn't seem to throw out enough heat. Temp gauge reads normal, around 210 or less, and it will drop to around 195, so I would think the thermostat is working.
Could it still be the thermostat or should I be looking at the heater core or possibly the radiator?
Also just replaced the oil pressure switch because my oil pressure would flucuate between 40 and sometimes 0.
Now I have steady pressure at around 42 pounds at idle or when driving.
Does this sound about normal?
Jeep runs good and doesn't use any oil and doesn't smoke. I also just replaced the plugs and they looked normal without any fouling of oil.
Thanks for any suggestions,
