Overheating Crap

I have an 87 XJ with a 2.5" lift on 31x10.50s and dual hayden cooling fans. Normally when the jeep is working and running per quo it doesnt overheat off-roading (unless heavily or in traffic). Now just driving it down the road seems to get the engine about 210 and off-roading just causes it to go wild. Is it because the fans dont have enough CFM of air being moved through them is something shot to hell:helpme: The last coolant flush was 2months ago.
Another cold night of wrenchin on the XJ at 35° :clap:

Check the water pump. I've seen the fins rust away to a point to where they get to a point where they are less efficient. With the age and milage, it is something to think about.

heres some good things to try:

If it's the original radiator, it's problably plugged up by now. Radiatorbarn.com and dpgoffroad carry decent all-metal CSF brand radiators for decent prices.

Will a triple core radiator fit or is a two core better?

I had a 3 row in my 92' just need to double check for fan clearance.

I've been having a similiar problem with my wifes ZJ. Couple weeks back did a tune up, a coolant flush and replaced the fan clutch. While I was at it I blew compressed air thru the radiator from the backside and to my suprise blew out quite a bit of debris.... I also seperated the radiator from the a/c condensor too, and found clumps of dirt, debris, hair, and bugs right where the fans suck air thru.. I haven't had any problems with the cooling since..
