Hello all, I have a 1990 Cherokee Pioneer. Started overheating about 1 month ago, I have since repaired the auxiliary fan so I can operate it with a toggle switch from the dash, installed a new thermostat and thermostat housing. I was driving up into the hills yesterday and once again about 15 minutes into the drive It started running very hot again. I pulled over and the coolant resevoir had a crack/hole in it and was spraying out/over heating. I went to Nappa and got a new reservoir with lid. I installed it, now the battery is dead, anyways, I replaced the battrery and it fired right up. I was driving it home and it started running hot again!? I turned on the aux fan and that seemed to help, a little??, but not for long. I'm still not 100% confident that the cooling system is operating properly. It is a closed system. How do I make sure that there is no air in the system?? I have to "Burp" it somehow don't I?? Im also concerned that the alternator is not charging the battery, I forget how to check that??? Any input would be apriciated! Thanks again!
