Puff of smoke every 3 miles
My 96 Deville is releasing a puff of smoke or steam every 2-3 miles on the highway. Also losing antifreeze but I'm not sure it is related. Running great, it's the weirdest thing I've ever seen.......Any ideas?
Thanks, Randy |

I'll assume the smoke is white? If the loss of coolant is related, check heads........................soon.

Sounds like the classic head gasket gone bad. Go to a reputable shop and have either a compression or a leak down test done. The leak down test is more accurate as the compression requires a fully charged battery to keep cranking the engine over while the leak down test uses a compressor to maintain air pressure.

Unfortunately the classic head gasket failure symptoms. You will eventually do serious damage to your engine by continuing to drive the car in this condition.

My post advised that IF the loss of coolant was related I would check the heads. Since it appears tha it is not related, do a pressure check of cooling system to determine the cause of loss of anti freeze.
Good luck. G.A.R.Y. |

Is the smoke/steam visable when driving or just when you stop?

I'd also suggest checking the water pump repair for leaks around the gasket. The water pump is in a location that can leak onto hot engine parts as well and create a steam like cloud too. Do you know if all the coolant was changed for the pump repair? Was sealer put in?

RE: Puff of smoke every 3 miles
The part that puzzles me is the clouds are in BIG BURSTS and then nothing for a few miles. Yes, I put the sealant pellets back into the system (twice). I did the water pump about 3 mos ago, the coolant just started leaking about 2wks ago. It's a mind bender. By the way the DIC is showing a steady 208-218deg on the highway so I don't think the thermostat is sticking as a friend suggested.
Thanks for the input, Randy |
