I everyone, I'm new to the forum and I have a question: I'm looking at a 1989 GMC 4x4, short box, V8 with 106,000 original miles (or so the owner says) on it. The body has been repainted and the interior looks good. I'm taking it for a test drive next week and I'm going to have my mechanic give it the squint eye. What should I be looking out for with this particular model? Thanks in advance!

If I were you, I would have bought the truck. The small things (rust, etc) can easily be fixed, and yes, it is correct - technically this truck already is a classic. I am personally considering a K5 Blazer.

1990 Silverado Radiator Oil Cooler Hose Fittings by hotrudderedbum

The truck is a 5.7L 2WD with only 137K on it and I hope to keep it forever.
 
I recently disconnected and bypassed the oil cooler hoses from the radiator while troubleshooting a curious high oil pressure indication. When I went to reconnect the hoses I found the lower fitting on the radiator stripped (the rad was replaced several years ago, too late to raise a warranty issue).
 
The nut that threads into the radiator is fine.
 
My question is...Is the female thread in the radiator an insert, sort of like a helicoil, or is the thread milled into the radiator body?
 
I'd really prefer to not have to put in another new radiator.
 
Any ideas?
 
Thanks!

1986 Chevrolet truck, 350 engine - Acceleration Dead Spot by warren73078

1986 Chevrolet truck, 350 engine, ¾ ton, 4 speed manual – bought the truck recently, after replacing carburetor, distributor, cap, rotor, wires, vacuum hoses, radiator, thermostat, also pulled emission controls off. I hauled a 27’ 5th wheel to the lake (80 miles), no problems and ran and pulled good, on the way back it developed a dead spot in acceleration between acceleration and de-acceleration. The exhaust smells gaseous. Checked all the vacuum hoses, connections, etc., adjusted timing. What now?
