Yesterday my upper radiator hose busted. So I call the local auto parts store nobody has the part for my car since its a 4.3l, I will never by a v6 g body again. I chose to order the part from autozone since they were the only store which could get the part yesterday. I ordered the part at 3 pm I had the part at 6:30 pm, with the truck running late. So replaced that and the most mangled rusty looking thermostat I have ever seen. I went with a 180 degree thermostat by duralast. I hope the idiot lights dont cost me the motor one day lol
