Assuming the t-stat is good, I'd look at the wiring next. Make sure the connector is clipped onto the water temp sensor/back of the gauge and that the wiring is not chaffed, etc. If that all looks good, replace the coolant temp sensor...they're $20 or so. If it still does it, the gauge is bad.

1999 Jeep Wrangler - 4cyl - 5 speed. Where do I start if my heater is not getting hot. Really doesn't get warm. Just blows out cool air. Side note: This is my 3rd winter with this Jeep and it's never...


The temp reading on the dash is a very big clue... Likely the thermostat (at the end of the large top radiator hose inside the metal housing) is stuck open. When that happens, the coolant in the engine never reaches full temp. Not only can that result in a low heat condition but it can also give you poor fuel mileage as the computer always thinks the engine is cold and therefore it adds extra fuel to keep it running.
Replace with a 195 degree(f) thermostat, run the engine (with the heater on full heat) to nearly normal temp, turn it off and wait about three minutes, then re-start and continue filling. Once full, add whatever is necessary to the recovery bottle and close it up and check for leaks.

I have a used 2000 wrangler 4.0 the air comming from the heater is not very hot .gauge shows around 200 degres do you think i should change the thermostat


no 200 degrees is plenty hot your thermostat should open at 195 degrees.check hoses to heater core make sure they are both hot if not you have blockage if they are hot then you might have a stuck blend air door.change thermostat as a last resort.

1998 Jeep Grand Cherokee Engine Stays Cold


If you have verified that the dash temp gauge is correct by checking temp of coolant in radiator,yes your guess would be what i would change,the engine needs to have a 195degree thermostat in it.195 degrees is what the computer is programed to see as normal running temp.

Proper operating temperature on 2004 Jeep Wrangler, Unlimited


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.

What the normal temperature operating range indicated on the temp gauge?


195 degrees is the typical high end on the thermostat (when the thermostat opens), so the temp gauge should read a max of 195 degrees, give or take a few degrees. Some people replace their thermostat with a lower temp one, such as a 180 degree one. Then the gauge will read lower (approx 180 degree max). So the range is typically from cold at start to just under 200 degrees.

1993 Jeep Wrangler heater/temperture gauge


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.
