1990 - hard start and overheat
My 1990 cherokee (182,000mi and counting) has been having a hard time starting...it's got a new battery and starter...i heard it might be the fuel pump so i'm letting that prime by turning the ignition to on for a while before i try to start her up...i was wondering if anyone had a definite fix for this problem...
and to add to my issues, she went and overheated on me today...after a standard 15 min drive i parked her and she overheated...no clue why...the cap on the coolant resevoir was a bit loose, but i don't know if that could have been from all the boiling going on inside... i know NOTHING about automobiles (i can't even find the bloody radiator cap) so any advice would be greatly appreciated... |

Clean your throttle body and IAC with some carb cleaner. this will most likely fix your hard start prob for a while. Get a new PCV valve to fix it for ~30k miles. As for your overheating prob, just search around. There are too many possible causes of that so just do some research and diagnosis work.

Re: 1990 - hard start and overheat
thanks much for the advice...but could you humor my ignorance and tell me what an IAC and PCV valve are?

Positive Crankcase Ventelation/Valve(Located at the front of the valve cover) and Idle Air Control(Located on the throttle body).
