Been lurking for awhile and decided to post for some advice on some cooling upgrades and advice. I have a 2001 XJ (obviously) with the 4.0, Auto, 231 TC, with everything basically stock. In March I installed a 2.5" OME Lift, JCR front bumper, winch, and roof rack with 6 KC lites. All runs well and works as it should. Living in Houston and with Summer knocking on our door I wanted to do some upgrades to the cooling system. The temp sits between 210 and 220 on a daily basis. Within the last couple of days it spiked to 260 for second and then back to normal. I have no leaks and just replaced the coolant with a 50/50 mix of antifreeze/distilled water.
The electric fan is what I am concerned about. I have noticed it will not come at with the AC (as I believe it should) 100% of the time. It is random. How can I go about testing to make sure that it is functional and what kind of upgrades can I do to beef up the cooling system without too much fabbing. I like to keep things as close to stock as possible....or at least the perception of stock.
