Re: Jeep Wrangler 2001 No heat or Temperature on gauge
See i you have any codes may be a temp sensor if you dont have a code reader you can still get the codes by putting key in ignition turning it on but not starting it 3 times after the third time the engine light will blink a series of times like morse code. be perpared to jot down the number of blinks the ligh gives of there should be a slight paulse between codes, there also is usually a start and end code thsi may take a few time to get it ..once you have the numbers you can google the code and find the problem googleex (Jeep trouble code 55) you can use this trick on any chrysler car from 80 on up possibly earlier.

its inside the heater box and need the whole dash taking out ,pull the two feed pipes off the heater and flush with a garden hose reversing direction of flow ,refill with antifreeze 100% neat ,then if still no joy put a piece of cardboard in front of rad to reduce the cold air flow through teh rad and engine compartment this should do the trick. dont beleave me watch ice road truckers and see what they do to their trucks to keep the temperature up .
you have a faulty thermostat in your jeep. the thermostat is on the engine where the top cooling hose attaches to the motor. it will look like a small valve type thing with a spring that holds the brass part against the steel. if you are replacing this yourself than you will want a 195 thermostat.
The thermostat controls operating temperature. This occurs at a preset temperature (typically 195 degrees F. or so), which is usually stamped on the thermostat itself. The thermostat should be fully open about 20 degrees F. above the rated temperature. So your operating temperature is about right. If you have doubts, just replace the thermostat with a new one of the correct temp.
If you haven't aleady, I'd replace the rad cap too.As far as the flow goes, It's usually easy to see big flow increase in rad when thermostat opens at about 190F-210F. If your not seeing an increased flow when gauge at normal operating temperature, then yes, water pump would be next. With that said, a compression or cooling system pressure test may be needed to rule out head gasket too. Does it appear to be losing/using coolant or just heating up? If it is losing coolant, then headgasket may be the problem. Let's hope that confirming good flow or no flow in rad, by visual, will answer your question.
if you are not showing a temp. reading ,you may need to replace the thermostat. as far as the draft goes your vent is probably stuck open. i also have a '93 with the same issue. i could not adjust the cable enough to close the vent so i removed the grill on the cowl in front of the windshield, the vent door is down and toward the left side (drivers side).if you can not push it closed to stay,i used a large piece of foam placed inside a plastic bag to block it. it has worked fine for almost 5 years.
