Hey guys,

Got a co-worker w/ a 86 Bronco w/ a 302. However it has a radiator from the V6 that was replaced before (some years ago).

She was driving home and in the course of 15 minutes, the truck overheated and lost power graduly and slowed down from 50 mph to 15mph before stopping.

Took it to the shop and they changed the thermostat and the starter (not sure why). The truck runs fine now.

My question being why would the truck loose power and come to a stop like that? I could see it overheating and blowing somthing up, but to slowly creep to 15 mph sounds weird. I'm sure that there is an easy explanation for this, but it is eludeing me at this time. Thanks!

BTW, they are replacing the radiator next week w/ a proper sized one.

 

Might not be a bad idea to get the tranny fluid changed as well. They don't like heat very much. Perhaps that is why it slowed down. Fluid got to hot and the tranny started slipping.

 

Maybe it got hot enough to vapor lock.
Did it have a carb?
I think 86 was the last year for them, my 87 has throttle body injection (CFI).

 

Well, thanks guys. Found out that she sold it over the weekend.

That makes sense. Knew you all would come thru!
