Hello all,
It's been a very busy summer for me so I have recently just begun to dig into this issue. Let me begin by saying that a few years ago I took some guys out to lunch in my car at work and the serpentine belt flew off right in the middle of a construction zone. Needless to say the cause was the alternator pulley was off by about 1/8" from the rest of the pulleys and just happened to chew its way through and when it broke it wrapped itself around the water pump about 942580342583 times. It boiled over and the temp gauge went well beyond the 280 degree mark on my mechanical gauge with me limping it and shutting the engine off on downhill slopes all the way back to work. Anyways, on my way home, I filled it up with water and all seemed well. It seems ever since then I have had issues with cooling to some degree or another. Come to find out after that my thermostat was stuck open and I think that was causing a lot of those issues after driving for long periods of time.
Fast forward a few years I put a new top end on the engine and I cant seem to get the engine to run cool enough for my own comfort. I put a mark 8 electric fan, a 180 degree thermostat, a brand new aluminum radiator. The car runs like a top and has all the power in the world; launches like a rocket, no missing, no smoking, or anything indicating a problem. Head gaskets are installed correctly, I done a compression check some time ago, and I checked the coolant for combustion gasses today. All turned out well.
I have recently gotten into the world of tuning and purchased a quarterhorse and have been working on my own tune. Working on my laptop at idle, the car will sit and run forever with the ECT reading 178 - 180 degrees. The minute I take it out and start driving it, the temp begins to climb under acceleration into the 200's. It was fairly warm today, about 90 degrees and humid but I sort of gave it the benefit of the doubt and drove it anyways. The temp hung around 180 for a little while and quickly began to climb into the 200's under acceleration. During deceleration, the temp will come down to around 188 or 190. When I pulled into the driveway, I shut it off at 204. Last time I datalogged, I was up to I believe 210. I feel that if I keep going then it will keep climbing, so I usually just find the shortest route home to cool it off. I am stumped. The only thing I can think of is possibly a radiator cap not relieving pressure when its supposed to? Or still air in the system. Or maybe my timing is off. I've searched in hopes with others having the same issue. I am hoping some of you can throw out suggestions. Any help is appreciated.
Thanks!
