Changed the fan clutch, thermostat, rodded a radiator that did'nt need it, it's been suggested to take out the thermostat. Could the water pump be bad with no visible signs? Runs good for 20-30 minutes then gets hot.88 4.2L carburated.

Re: Hot, Hot , Hot.
Yes. You cant see any of the working mess. Changine the water pump is cheaper then fixing a trashed motor from overheating. I'm not sure about 4.2's but the 4.0's need to run around 210 for it to be efficient and run properly. Good luck.Originally posted by paulhead

So what's the deal. After it overheated I let it cool for an hour. So I pop off the cap ,went to start it and it was at 210*. Then after a few minutes went up to 250 but it was'nt boiling over?“Lead me, follow me, or get out of my way. ”

boiling over? is 250 even close to hot enough to boil rad fluid? you are using radiator fluid right in a 50/50 mix or whatever, not just water?Originally posted by paulhead

Yea Rick, that would've been my next step . But I thought to change the sending unit just to see what would happen. Sure enough, drove it all around for over 40 mins, on street, freeway, and temp did'nt budge past 207*. I am a happy camper
. Thanx guys.
