Part 3 of 3: In this video I’ll show you how to convert the older XJ Jeep Cherokee closed style cooling system to the newer open style cooling system. I believe Jeep made the switch in late 1991 so If you have a later model Jeep Cherokee this upgrade doesn’t apply to you. This is quite extensive and I’ll cover it in three videos. First we’ll take out the old radiator and and coolant bottle along with the hoses, thermostat housing and replace it with a new radiator with a cap, a new open style coolant bottle, and some new hoses and new thermostat housing. I’ll also show you 3 ways you can hook up your auxiliary fan to still work with the new cooling system. By the time were done you will have an entirely new and updated cooling system and hopefully keep your XJ running cool.
***UPDATE 05/25/2013 – It appears they now make a radiator that has a radiator cap and the hole for the older XJ stock temp sensor. So if you are buying a new radiator then you might want to get this one and you wont have to fool with the wiring mess I dealt with in the 3rd video. It is made by Spectra and the Part # is: cu1193. If anyone knows of other radiators that fit please let me know in the comments. UPDATE****
