correct temp for a jeep? Please Help
1980 CJ7 with stock I4 2.5L. Here is my prob. put a new thermustat, hoses, heater box, more hoses, and a new gauge, radiator, waterpump and coolent...and yes if found more new hoses, in last year. The jeep ran a consistant 180deg untill summer then it ran 190deg. Recently it would peek at 200deg and drop to 190deg. sometimes it would stay at 0deg for along time jump to 200 adn fall to 190deg. Untill yesterday, it peeked at 200deg and dropped to 170deg. So this morrning I replaced the thermostat (they parts store I bought the first one from has sold me several defective parts...no logner my parts store.) New thermostat in and topped off the coolent, left the cap off and let the jeep idle to temp with the heater on full. Jeep got up to 200deg and dropped to 190deg. Replaced the cap ran at about 2000rpm for few (min no leek) and the jeep stayed stayed between 190 and 200deg. Rechecked fluid still full.
So What-the-hay?!? Chiltian says the 4cyl COULD run up to 205deg. My experence with my jeep is 180deg. What is a "normal" operating temp for my jeep.
With the 2000rpm I was in the garage with the hood up. I havnt driven it yet. Maybe the air flow will cool it down?
