Re: 1982 GMC s-15 Q\'s
Sounds like time to check the thermostat.. Rather than trying to test it, it's easier to just go to the parts store, give them about $10 or so, get a new one, and toss it in... The steering and water pump are connected by the same belt(at least on my '85), maybe since it's over heating, your water pump is worn out, the impeller in there could be eroded, and it's not flowing enough water.. Maybe your radiator is a bit plugged/scaly? I'd try the thermostat first, then pull the water pump, and check that out, and that should rule out the radiator, just check in there to make sure it doesn't look too scaly or otherwise full of junk...
