1996 Chevrolet Lumina radiator fans won't kick on and the oil is 5 times as high as it was when I changed it.

Asked by Michaeltrpt Jul 15, 2014 at 01:46 AM about the 1996 Chevrolet Lumina LS Sedan FWD

Question type: Maintenance & Repair

I have replaced the thermostat and tested all the fuses and
relays. The fans won't kick on and it appears like someone
has put an additional 5 quarts of oil in. I don't know what the
problem could be. If you have any suggestions as to why
this happened especially the oil thing I would appreciate it.
The car has just under 271,000 miles on it.

The oil does look watery now that you mention it. Would that cause the fans to stop working too?

Your coolant temperature sensor could be on the Fritz. Try unplugging the sensor, it has a yellow, green and black wire plugged right next to the thermostat housing. If the fans kick on, it's the cts. If after replacing and resetting the check engine light, nothing changes, you have an Ecuador problem, which is common for the 3.1 engines. Let me know what happens.

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
