Cool Keeping a CJ from Overheating?????

Hello, I have an 83 CJ7 258ci w/ 33s. I have the factory fan and everything. My water temp gauge doesnt work. Is there any aftermarket things I can do to keep the engine cool. Or anything I can do period to prevent overheating. Will an electric fan work or what else? Thanks for responding,

they make electric Pusher fans that mount on the front of the rad. but if i were you i would invest in getting that temp guage to work. but the way the pusher fans work is to "push" air through the radiator while i think keeping the stock cooling fan on there

hope that helps

Is there any reason why you want to spend hundreds of dollars to install aftermarket cooling componants instead of repairing the temp gauge? Seems like knowing is better than guessing. Repair the gauge, then if you have cooling problems we will be happy to help you find out what is wrong .

When you replace the temp guage, replace the fuel guage at the same time.

Other things to keep your CJ cool:

Make sure you have the fan shroud installed (this is essential!!!)

go with a 180 degree thermostat

flush the cooling system

Inspect the fins on the radiator and make sure
that there's not a large chunk of them folded over. If they are, you can get a radiator comb to straighten them out.

Make sure the cooling system flows through the intake manifold and that it hasn't been bypassed.

Make sure the heater core hasn't been bypassed.

Make sure you don't have a clogged hose (due to corosion)

I had to do all of these things to get my CJ running cool, but now I can creep along all day in 100 degree temperatures without it overheating.
