SOURCE: Jeep wrangler Fuse box

i had the same problem. i drive a 95 so im not sure if it differs from were the fuse box is. look righ above you pedals to your far left. it should be right there. also if you instruments went out it will be a 15 fuse. its a blue fuse. next my panel went out cuz of the wires on my transmission. if yor looking at your jeep at the front. the wires will be on your left. make sure they are not burned or anything. it will be right on the side of your tranny. mind got burned by the exaust so they were shorting. check that is and see if that is what is it. for a temp fix just put some electrical tap around the wires and you should be set for a wile. good luck

SOURCE: 1992 jeep wrangler 2.5 liter engine still overheating

Did you put a new cap on the radiator? Small as it seems, if it does not provide an adequate seal on the radiator, than the system does not get pressurized, thus keeping the boiling point around 212 deg. your engine gets way hotter than than normally. When sealed right, the pressurized system raises the boiling point to close to 300. thats how is works. If thats not it,(assuming it is the last thing replaced) than you might have either a cracked head/ head gasket/ valve guides, cooling ports, basic large dollar items. Lets hope for your sake the problem is still in the cooling system, before you look at the motor. If you take out the sparkplugs, you'll be able to tell real quick, rusty, burnt whitish-orange looking condition. Good luck

Try this disconnect the heater hoses from the heater core use a hose to backflush the core. Then reconnect and try again.

2006 CHEVY COBALT OVERHEATING HAS NEW RADIATOR WATER PUMP AND THERMOSTAT


That is normal, it will not get hot without the thermostat. The water cools in the radiator and falls to the bottom and the bottom hose is cold. This is what cools the engine and stops it from overheating.

My 2004 A4 1.8 Audi's water temperature does not go above 150 degrees F. What can be the problem


Check the engine thermostat!

Thermostat checking:
1. Cold engine. Start up the engine and watch of the water temp indicator. After first value 140 degrees F you still warm up the engine until the lifter (pointer) reach 175 deg. F (second mark after 140 deg. F). At this time you let engine running at idle speed and check with your hand the thermostat plastic housing and hose temperature in bottom left side of the engine. Heed of alternator driving belt and ventilator fan !!!
2. If the thermostat is good the hose must be cold until the water temp indicator reach almost 195 deg. F.
3. The thermostat opening temperature is 188 deg. F.
4. If the hose is already warm the thermostat is out of order.

Replace the thermostat if necessary!



Please do rate my response. Thanks!

1994 Jeep Wrangler, heater problems


Sounds like the blend door that diverts air flow inside the heater box is not working, or, the heater control valve on the heater hoses in the engine bay is not closing.

When my 1998 wrangler reaches 190 deg.F it experiences hesitation lasting 5-10 sec. then runs fine.somtimes backfires thru exhaust.


Translating what you just wrote, it hesitates just as computer changes from closed loop (cold) mode to normal running mode. I'd first check the temperature sensor (computer reads it to know when to switch modes) Also, check the map sensor. it indirectly controls engine timing and fuel delivery. Another item to check is the manifold air temp sensor, which also influences fuel mixture. I don't recommend you run out and buy any of those items but you can test them with a digital volt/ohmeter using either haynes or chilton manual as a guide.
