I turn on my heat and it feels like I am in a sauna, windows become fogged and I find coolant leak at the floor on the right side.
Is it the water pump /heater core?
The temp gage on this vehicle has never worked, so I have not driven it since, b/c it is toxic and second don't want to damage the engine
What? I love this van!

Hello, This could also be a problem with your thermostat. I would recommend bringing to a mechanic to diagnose so you don't spend a lot of money fixing the wrong problem. I hope it works out! Best of luck! CarGrrl

My Lumina's "Service Engine Soon" light came on as I tried to turn over the ignition. The engine turned over, however the engine seemed to be oscillating and shook the car. I turned it off, popped the hood. I couldn't find anything visually wrong. So I turned it over again, same idiot light and oscillation, however I noticed smoke coming from the electrical component up front under the exhaust manifold. This car is a 1996, w/ 155Kmiles and a new computer and 50K on the new trannie. I love the car and don't want to get rid of it, what should this be? Is it worth repairing? Is the smoke (like that of a burnt electrical component) related to the oscillation? I would appreciate any help you can provide. Thank you 1 Answer

1996 lumina, LS, 3.1L. We use only synthetic oil. I noticed the oscillation and idiot light together. the smoke was a couple of days later when i tried to trouble shoot.

I have a '99 Chevy Lumina LTZ, and for the first couple of years that I had it it would never really heat up until the past two years, when I noticed the temperature gauge actually moving. Anyway, when it heats up(needle in the center or right in the gauge), my car shakes and it shifts really hard. Any ideas? It has 172,xxx on it, and I'd like to get another year or so out of it without replacing anything major. 2 Answers
