YJ "normal" Coolant temperature?
Brand new to Jeeps. Mine is 1989 4.2 I6 and Auto. Friend I bought it from
was very good about explaining to me about making sure it does not get hot.
But what is normal? It will run below the 210 line on the gauge while driving
and may go up to 200. Then when in town it will kit up to about 220-225
an idle at a light. Sometimes just below the next line on temp. gauge(230?).
I read the manual about putting it in N and giving it a little gas to increase
the RPM and when I do this it does jump back down to 190-200. So first
off is this "normal"? Secondly he added a Tranny cooler because he was
worried about heat. It blocks part of the radiator and so does the A/C condenser. I think he has be worried that this was making engine run hotter.
So again, does this sound normal to you guys? Oh and it is like 95-100
degrees here in Oregon when this happens. Thanks.
Also, it seems that the gauge moves abruptly? Could be sticking?
And the Oil pres. gauge is pegged at 80+ Sorry to be long winded...
I have an '88 with a manual transmission, but it does the same thing. I don't know that it ever climbs that high, but I can keep it down by letting idle a little high (1100 rpms) at lights. I am at some point going to put an axillary fan on it to try to help and I have seen a water pump that is suppose to flow at a higher rate at low RPM's.
Don't know if that helps too much, but I do see the same general thing happen to mine. After a while, you learn what your Jeep needs to stay happy and you don't even think about it :)
that you have to shift to neutral that it must just be a Jeep Thing.
Just wanting to keep my new baby happy.
