My 1994 jeep Sport needs a new thermostat. Can I replace it my self? How hard is it to fix it? Anywhere I can look to fix it? thanks...

super easy, you should invest in a haynes repair manual. it well tell you step by step how to replace anything really and there only like 20-25 bucks at autozone or checker.

cool,thanks. Are most repairs fairly easy on a Jeep?

Doc Brnard

Some are, some aren't. Standard maintenance stuff, piece of cake. But anything major, maybe beyond the standard tune-up mechanical aptitude.

+2 on the Hayne's. Consider it your Cherokee "bible".

dude i have two of them. one in my jeep and one under my pillow

Doc Brnard

Such dedication........*sniff* I am humbled........



LOL! Just messin' But you have a good point. Know how to use the Hayne's..........and the intimate secrets of your Cherokee will open up to you. But just like good lovin', don't be afraid of getting a bit dirty. Damn! New sig line.

One caveat when dealing with 4.0 thermostat housing.
Make sure you tighten the bolts equally, DO NOT TORQUE ONE DOWN THEN THE OTHER.
You will need a new housing if you do.
It will break an ear off the housing.
I've broke two so far. I as being extra careful on the second and still broke it.

YOu can get the bottom bolt out without removing the belt and back in if your careful too.

X3 on the Haynes book and IMO replace your 195* thermostat with a 180* No need to run the motor that hot unless we are trying to pass emissions.

And when you start doing mods on your XJ. Loose the haynes manual and get "Eric's" book . http://ericsxj.com/
