Hot CJ
I have a 79 CJ with a 258 motor. It overheated pretty good. Running 60 mph
when noticed. No water in oil and head Gasket seams to be fine. I replace the radiator, water pump and thermestat with a 195 deg. ALL are new parts not used. The thing runs fine. Even passed Emission (what a relieve). BUT....The temp gage says it's running hot. It rides on the "H". It ran 1/2 to 3/4 before this all happened. I think maybe the sending unit is bad. I will replace it today. Also the fan belt was replace early summer. I will replace it again as well. I know the rad is right size as a 6cyl is the same as a 8cyl. So there was only one coice. Is it possible for a sending unit to go bad??. I'm out of parts to replace. ANY input would be helpful. THANKS Big Don 79 CJ / 98 XJ |
Re: Hot CJ
Hi Don,
You have the wrong water pump. As has happened to me two for two, they were boxed wrong from Pep Boys and Kragens. The pump you put on was reversed to use with the serpentine belt: http://www.----------.com/waterPump.jpg God Bless America, ßill O|||||||O mailto:-------------------- Big Don wrote: > > I have a 79 CJ with a 258 motor.
