Hello, I have another question about my 84 Z51. After sitting at the shop for several months, and getting a new trans, new axel stub, new brakes and a few other things, the car would overheat. After inspection we found that someone had put about a ton of stopleak material in the cooling system. The bottom of the radiator and the lower part of the block was plugged up. I was going to have the engine and radiator rebuilt. I had the radiator rebuilt. Yogi at Bair's Corvettes in Linesville Pa suggested to my mechanic a Caustic Spray before rebuilding the motor. They sprayed it into the top of the motor and front of the block and after a week flushed a ton of gunk out of it. The car runs very cool now. It has had 2 190deg thermistats put into it and it consistantly runs at 160 down the road. Is there anything other than the thermistat that would make the car run this cool? Granted, it was about 55deg outside the day I drove it. I thought it had to run arround 190 for the computer to go into closed loop mode. It seems that the thermistat is not working properly. I have checked it with a manual gauge as well as the dash guage and it runs at 160. It also seems to take awhile to warm up. I figure next the motor will start using antifreeze and will have to be rebuilt anyway. Any ideas?? Thanks.. ..Tim
