Re: 2002 jeep wrangler OVER HEATING
Run it for a while and check the two heater hoses to the fire wall for the heater core. Turn the heat inside on low and floor. The hoses (when the jeep is hot) should be about the same temp. One will be slightly cooler than the other one. If this is not the case and one is much colder than the other you have a plugged heater core. Mark the cool hose let the jeep completely cool remove the cold hose and the hot hose use a garden hose to flush the core in direction of the cold side to hot side. If this is not it you have a air pocket in the system or your blend doors in the air box under your dash are broke.

my used 4 cyl jeep radiator would only drain 1/2 of the fluid. jumped up and down on bumper and this dislodged the sludge in radiator and/or engine. flushed twice, then now notice low temp reading on gauge (out of specs) due to a low temp thermostat that someone installed due to previous over heating (sludge). Replace with factor spec thermostat and everything is fine.
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.
hi, i have a 2000 wrangler that was having the same problem. i replaced the thermostat, the the water pump and the figured out that the radiator was getting sort of clogged with rust debris. hope this helps
