Replace ur mechanical fan with an electric one and switch to synthetic gear lube. That should help.

 

I;m new to the Jeep world,,i just got a 95 Cherokee Sport 4.0 It has 2 fans on it a Mechanical and right next to that a electric one.. What would I need to do go buy another electric one off a jeep..and mount 2 on it?

 

You would think just adding another XJ electric fan would work but it's been tried and it doesn't.
You need something that pulls in excess of 1800 CFM to properly cool it along with the stock electric fan.

Your going to hear this a lot on this forum but if you do a search on electric fan conversions, you'll find several write ups that will help you make your decisions.
Be sure to search the home page of this forum and look for the write up section. A lot of very good tech articles are stored there.

 

Tornadoes are on the same scale as a throttle body spacer, if it sounds too good to be true, it probably is

 

ya dont wast your money... the intake valve will only let in that the cam will allow.

 

save your moneny and get better injectors with four ports instead of two.

 

I gained almost 2mpg just by running 35psi in my tires, removing the roof rack, and using my cruise control when ever I can.
