SOURCE: Can't figure out how to change the bulb for turn signal on Jeep

it can be a pain because the screws are hidden. first you must remove the parking lamp raise the hood. one screw is visible from the top looking down at the lens...the other is hidden on the bottom side....look between the park laml and the turnsignal housing..a long phillip scew driver can reach it. once you have that removed lookng straight down at the turnsignal assembly you should see 2 screws. remove them and roll the assembly out and away from the body...you should see the bulb holder

SOURCE: my jeep grand cherokee started overheating at idle

try the water pump - first - make sure the radiator is really full - take the cap off cold and fill - if it looks full - start and run 8 minutes or so - then fill it up - look at ur fan belt - is it tight - tight is about how much pressure u use to make a firm hand shake with little movement - any movement over about an inch is loose - when the jeep warms up the belt can slip and not even make a noise - - new materials don't always squeal. - then be sure ur water pump is ok - they go slowing - the fins wear down - one more thing is the radiator - u don't say how many miles or what maintenance schedules you have or not so that's it for now

sounds like you have blown the internal heater matrix and the thermostat is not working or is blocked. you are going to need a new matrix and thermostat and a bloody good flush out of the system just in case there is something in the system means taking off the rad hoses flush them out from both ends. and doing the same to the engine. replacing the matrix as its not going to be able to fix it if its shooting water out of the vents change the thermostat check pipes for damage.

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.

1998 jeep grand cherokee cooling problem


Your thermostat is stuck closed. It needs to be changed right away. By the way the operating temp on that motor is 160 degrees so you are running hot you have just been lucky so far. Good Luck
