Chevrolet Lumina Repair Question
Asked on July 20, 2007
White smoke from exhaust
I have a 97 chevy lumina v6 3.6 the engine was rebuilt so i dont know how many miles it has now, but heres my problem when I turn on my car white smoke will come out of the exhaust pipe not a lot but enough to notice like as if it was winter but it doesn't go away and i also notice that it overheats and that the fans don't turn on at all. I have checked the fuses but they all work i dont know how to check the big square fuses though those are the only ones i didn't check, but white smoke doesn't come out every time i turn on the car maybe 3 out of 5 times it will appear and when it does it does not go away. I have no idea what it could be any advice would help thank you.

THE REASON THE FANS ARE NOT COMING ON IS THAT THE FAN RELAY IS BAD OR THE TEMP COOLANT SWITCH IS NOT WORKING. AS FOR THE WHITE SMOKE OUT THE TAIL PIPE. WHITE MEANS WATER, BLUE MEANS OIL AND BLACK MEANS FUEL. YOU HAVE PROBABLY HAVE A SLIGHT BLOWN HEAD GASKET. IF WHEN YOU GET THE FANS TO WORK AND THERE IS NOT TOO MUCH WHITE SMOKE COMING OUT, YOU CAN TRY SOME BLOCK SEAL TO TEMP FIX THE PROBLEM, BUT GET GOOD STUFF AND FOLLOW THE INSTRUCTIONS.
