#27 of 36 1990 Silverado Radiator Oil Cooler Hose Fittings by hotrudderedbum

Mar 16, 2009 (6:22 pm)

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, 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?

I just bought this truck,it has 78,000 miles on it and I thought it was a good deal, 350 engine,auto. I have several issues:
Heater: I can't get the heat off the floor. It won't blow on the mid range dash vents or on defrost. I have removed and taken apart all three actuators and they all seem to work. I have pulled apart as much of the dash as I can to get to the vents thinking they might be jammed or rusted shut. I am unable to get close enough to manually open them. I noticed the radio controls for speaker settings are sketchy and wondered if it isn't the push button controls for the heater system that are bad.
 
4 wheel drive went out on me Christmas morning, stranding me in the sand for a couple of hours.It went into 4 high, the fell out into 2 wheel only. I have the stick on the floor shifter system, light doesn't go on. I had to be pulled out. I have read about the "shift actuator" in other posts. Maybe that's it, I don't know. I figure with the low miles and barley used 4 wheel drive by previous owner, it can't be anything big like the transfer case. I can't figure out why they don't make these actuators fail in 4x4 only so you don't get stranded in 2 wheel drive..
 
Radiator leaks. I can handle that though. Kind of disappointed as I am used to old Jeep CJ's with manual hubs and go anywhere attidtude.
 
Body is in great shape and it is a looker. I want to get it up to speed mechanically and drive it lightly. I appreciate any help.

#34 of 36 Power steering fluid cooler replacement by portola1

I think my power steering cooler is leaking. Anybody know how to get to it? It is attached to the radiator on the side. I can see it though the grill. Maybe I have to remove the grill to get at it?
 
Thanks
