Over the past year my truck had been suffering from an intermittent overheating issue. Driving along and the temperature gauge would climb and peg itself and then just as suddenly drop back down to normal. Me being the procrastinator that I am I basically just ignored it since it only happened once or twice a month. I briefly mentioned it to a friend of mine who is the service manager at another dealer and he suggested that maybe the thermostat was sticking. This made sense since it had never been changed and it was also the simplest thing to try. Swapped out the t-stat at home and afterwards the truck wouldn't cool at all. So I'm thinking must be a flow issue, I called my friend and said I would be bringing it over in the morning. Next morning, cold and snowy, I couldn't drive more than a mile without it overheating to the point of reduced engine power. My friends dealership was over 20 miles away so I limped it the 2 miles to the local dealer, Blaise-Alexander Chevy, formerly Hicks Chevrolet of Greencastle PA, which is where I bought the truck incidentally. Told them the issue and went home thinking maybe I'd be springing for a new water pump or radiator. Get a call some 6 or 7 hours later and the service manager says " Hi Mr. Hudson, your head gaskets are blown and you need a new engine" I reply "Er.... what?" So he proceeds to tell me that they tested it and exhaust gases are getting in to the coolant and they don't change head gaskets anymore as it is too costly in labor, they just put in a new engine.I go back in and he offered me a G.M. crate for $3800, a Jasper for $2800, a local knock off "Jasper" for $2100 or a salvage yard motor with 118,000 miles for $1800. At this point I'm looking at him with my mouth hanging open thinking WTF! So he then takes me back into the service area to "show" me the test they did. They put the bottle of blue fluid on the coolant reservoir and pressurized it and with the engine running I waited for it to turn yellow. After 5 minutes it was still the color of blue mouthwash I looked at him and said "well?". He said "It turned yellow this morning". At this point I say "Give me my keys. How much do I owe?" I drive the truck home, overheated twice in 4 miles, and the next morning had it roll-backed to my friends dealership, Hoffman Chevrolet in Hagerstown MD. He and I went to high school together so I trust him implicitly with my vehicles. They checked it out, pressure tested each cylinder, put on a new water pump ( at my request since it's at 130,00 miles) and after the second test found the bottom half of the radiator was clogged. $400 or so and I'm back in business! So I highly recommend, 1. Don't go to Blaise-Alexander! 2. DO go to Hoffman Chevrolet! 3. Get a preventative coolant flush! The funny thing was, my friend said "What were they going to do after they put in the new engine and it was still overheating?"
