Overheating issues

Hello, I am new to the forum thing but hoping someone out there can help me. Over the last week or so my jeep has began to overheat slightly and the heater in the cab doen't seem to work very well. It overheats more while driving at slower speeds or when stopped. I thought maybe it is a problem with the thermostat or fan clutch (it seem sto be running more than normal). Are these hard to replace?

thanks for any help!

what year Jeep do you have? JK, TJ, YJ, or CJ? I can move this to their specific section to gain more attention

Did you check your coolant levels in your radiator and reservoir? That is definitely where you should start. A low level will cause the overheating and the weak het output.

I checked leavels and added fluid to the coolant bottle. Below are a few other things I have noticed...
-The temp seems to rise and fall no matter what the driving condition is (stopped or moving). It will rise then fall and repeat.
-Running the A/C full blast has no effect
-As metioned before the heater is weak at times. Seems like when the temp gauge starts to run hot then the heater blows hot as the temp starts to fall then the heater blows cool air.

It's great that you have heat now ant that your jeep is not over heating BUT, since the coolant was low you must have a leak somewhere. Get it checked out before you get stranded somewhere. It could be something simple as a hose, hose clamp or it could be the radiator, heator core, water pump or even a headgasket. Let us know what you find out.

No problem. Glad it helped you out!! Just keep an eye on the level. If you notice you're still losing some, I'd get it checked out, but I'd personally just keep an eye on it for now.

BTW, just saw your location. Tell me your a Cowboys fan and not a Texans fan. I've been a lifelong Cowboys fan even though I was born and raised in Indiana. I'd hate to think I helped out a Texans fan. Haha. Just messin with ya.

Been driving the last few days with no further problems. I am going to keep an eye for leaks or other problems. Sorry, not a cowboys fan but my wife is if it makes you feel better. And no, not a texans fan either with the season they have had.

Thanks to everyone for the help.
