I’m planning to flush my cooling system and I found a nice web site that described the process:
http://autorepair.about.com/od/regularmaintenance/ss/coolant_flush.htm
Will this be a ok way to do it on my 1994 4 L Cherokee with automatic transmission and NP242 transfer case (just listing my cars specification because I have some other questions)?
I have been reading and searching a lot on your excellent forum, and I have learned there is a plug on the engine for coolant taping. Should I also unplug that when draining the coolant fluid, and should the heater be closed so no fluid can get out from it (and should it be closed when I drain the radiator flush substance)?
What is the correct way to get the air out of the system, I have read on Norwegian forums you should start the car in an steep up hill whit the radiator cap of, let it heat up, and top of with coolant fluid as it air itself out? I have read on your site you should park the car in a down hill whit the number 6 cylinder higher then number 1 and open a temperature sensor to let the air out, but how will the air in the heater core get out in this position?
And over to another question:
If I remove the tranny cooler lines (they go thru my radiator for some reason, is that normal?) will there be oil in them, or do the oil drain back to the transmission bottom of it self?
Hope some one can give me some answers since I have no mechanical experience with the Cherokee, and I hope you can understand my lousy English
Best regards
