I am having a problem with my 1999 chevy tahoe, it was -4 degrees outside when I went out to start my truck. I drove approx 20miles and the gauge for temp went all the way to the right past redline. I got off on the next exit and the truck died. I turned the car off and opened the hood to see if there were any problems I could see. The overflow tank was bubbling and then would stop and do it again a few mins later. I did not have much steam coming from the radiator and there was no pressure when I opened the cap. (has a red lever to release pressure). I opened up the cap and added some more antifreeze. A "mechanic" stopped to help and said that since the engine was not "hot" I should try and start it. I had been sitting on the side of the road about 30mins. The truck did not want to start like the battery didn't have enough of a charge. The man attempted to jump my truck but put the cables in the wrong position on his vehicle. It sparked when he attached them to my truck but he said that was because of the snow. I told him to stop and had the truck towed to my house. I bought a new battery and started the truck. I let it run and noticed that the check gauges light came on and the needle again dropped to below 260 then dropped to cold. It ran for a total of 35min. I went and bought a new thermostat and put it in. The truck started up and after about 5 mins the needle did the same thing. I turned off the truck and came here to ask what next. I am out of ideas and do not have a clue. Any help would be appreciated, thank you.

Why are we digging up 6 year old posts?

 

Likely a ford Troll. Going to have to look at the dates before posting.
