holy crap :shocked

thats huge! and friggen expensive. would it be a waste of time to go to a junk yard and pull one from something?
Don't waste your time on a radiator from a junkyard. It likely won't be in any better condition than what you have.

If you know this radiator is at least several years old, then make the decision to flush your system good and try that as a cheaper alternative, and if you are still having problems, just go get the heatbuster, it's likely 2x's the radiator you have now anyway.

I had the bronco tow package and supercooling, so mine was at least a 2-3 core stock, and this radiator was bigger yet. 5 years now and it's been great.

ok.. bringing back the thread here.

i havent flushed yet, BUT i did add a mech. temp gauge and its working beautiuly (thanks SigEpBlue).

i drove up a a gradual mountain road that went up a few thousand feet over 5-8 miles, maybe doing 45-50. i was keeping my eye on the temp and it never really rose above 205* and started having the same symptoms as my "overheating" problem. :banghead:banghead:banghead . it suddenly looses power, with hesitating and hick-uping and as you pull over it always shuts off. WTF!! this time could touch the pressure cap too right after pulling over... so thats not very hot. after 10-15 minutes with the hood popped, we can start up and go w/o symptoms and drive easy, but this time we went up another 800ft over 2.5miles and it crapped again. let it cool for 10 min, went DOWNHILL, went up a mile and crapped. never did the temp rise 205* when she threw a pissy fit.

i'll admit that im out of ideas, becasue to ME it doesn't sound like its overheating. my only other idea is that the fuel pumps are vapor locking? and i dont even know if that is possible.

PLEASE, PLEASE shoot me ideas, before i have to take it in. :whiteflagbefore i do that, im gonna pull codes and flush the radiator for good mesure. but i'm up in the mountains this whole week.

sorry for the long post, i just wanted to be as through as possible.
Fuel pump is going bad. When was the last time you changed the fuel filter?

These are the exact symptoms mine displayed when the pump started going bad. It can't quite deliver the pressure within the range specified so you begin to have these issues, either 1) when climbing hills/mountains and gainging altitude, or 2) mine would do it on very hot days.

Pull over, pop hood, let it sit and cool some, close hood, drive on.

ya thats exactly what mine is doing! there is two fuel pumps right? one in the tank one... somewhere on the frame? Fuel filter was replaced less than 6 months ago.
For you, if you are an '89 model I believe so. Mine is a single in tank pump.
