Chevrolet Lumina



  • Hi, I'm an owner of a 1996 3.4L Chevy Lumina... its an awesome car I love it, but I'm running into yet another problem, the fans on the radiator like to come on when the car is cold. today 11/20 it was about 34 degrees out side and when I started my car the fan came right on... I drove it 35 miles to school and when I shut the car off, the fans stayed on. it did it to me before in the summer but then the car was running hot, now that its winter time its not so hot outside and the engine temp. gage didn't say that it was hot.. so what could be the reason for my fans to come on???
  • Coolant temp sensor could be bad, reading hot, but this would usually cause hard starting cold also, I would look for a bad coolant fan relay, first.

    I rode in a Lumina cab in Dallas this week with 3.1 motor. 266K miles. Another happy owner.
  • I have a 98 lumina with 99000 miles on it...dervice engine soon light came on, brought ot to local mech. he said it just need tuneup, after spending a few dollars, light still on, now they want it for annother 3 hrs. to saying its missfireing and needing the injector replaced/repaired..another good buck, i ve been thinking of getting new car, but with this being an issue, is it worth it to repair (hopefully as he wasnt sure that this would correct it) or should just trade in? any body have a good idea?

    take it to a a shop with diagnostic equipment to find out what the problem is before you spend money on fixing anything; may be able to have it done free at Auto Zone
  • hi me again... i just took my lumina in to have the antifreeze leak check, both head gaskets are bad and it cost roughly 850 dollers to have them it worth it or should i trade it in and get a different newer car with less miles?
  • Be careful with that diagnosis, it is more likely int. manifold gaskets, this was very common on the 3.1.
  • i am also an owner of the 3.4 lumina and the fan sometimes stays on or goes on when its not hot ,,but another thing that bothers me recently is when i start the car after a drive within an hour it will start then shut off,,im wondering if a tune up would help,or just spark plugs?? any info appreciated
  • i just want to make it clearer,,,after a drive if i come back to start my car it may start but then shut off within a sec.
  • my 3.4 stalls alot too... usualy only right after i start it but sometimes it will do it when i park it too. im not sure what to say. i love my car but the little things drive me nuts.
  • How do you remove the pressure hose fitting at the rack end? I have a 96 with a 3.1 and I can't find an angle to get a clean grip on this fitting. It looks like I'll have to remove the brake booster to get at it. Any ideas?
  • I just put new KYB's on the LTZ, a fairly unpleasant task. Paid $220 for all four at the Tire Rack. Got the necessary tools from Auto Zone under their free loaner program. When I took the cartridges out of the front struts, they came out in two separate pieces and most of the hydraulic fluid had leaked out. The rear struts felt weak with erratic dampening, so I guess they were shot too. How long are struts supposed to last? The car has 50,000 miles. Have a good'n!

    It depends how much hill hopping you do, but I've got one vehicle with 62K miles on original struts.
  • I just looked it up, and Yahoo autos says struts generally last from 30 to 60 thousand miles. I didn't know that. The only signs that the struts were worn is the tires were cupping badly after 15,000 miles. Ruined them in fact. The car passed the bounce test, rode smoothly, handled O.K and there were no external oil leaks from the suspension.
         The new struts provided an added bonus over the expected results. They eliminated a clicking, popping noise from the front of the car whenever I turned the steering wheel, either stationary or moving at low speeds. It sounded like a bad CV joint. They got rid of most of the rattles too.

    IMO this is not a DIY job for most people. You can risk serious injury.
  • If you are not careful, it can be extremely dangerous, especially when compressing the coil springs. You have to follow the instructions exactly.
         I've done most of the work on my cars for years now and struts are nothing new, but if you are unfamiliar with suspension replacement, I strongly urge you to leave it to the pros. I was addressing the people who have enough ability to undertake this repair,and they know who they are, but I was negligent in pointing out the potential for serious injury to those with little or no experience. So pluto5, thanks for bringing this up. By the way, how's the Impala? I've been lurking in that forum for months now.

    Very pleased with Imp, LS is worth the diff over the base IMO and still a great value esp. with all available rebates and discounts. I want to run the Lumina for at least 4 more years and then buy another Imp after I rebuild my GM card earnings since we need 3 cars.
  • All this cold weather has me wondering why the Automobile Manufacturers haven't yet put a small electric heating grid in the air distribution plenum. It would cut down on the warm up time, save gas.

    Do you mean an electric heater for the passenger cabin air, or an electric heater for the combustion air intake to the engine?

    Either way, it would not save gas. You are using electricity to run any electric heater, and that is generated by the alternator, which uses engine power, thus consuming gas.

    Internal combustion engines by laws of thermodynamics never will be 100% efficient. The waste heat energy has to be dissipated anyway, so part of that waste heat is what is used to heat the passenger compartment in the winter. It is not a good idea to use electricity generated by the alternator to heat the passenger compartment when you have all this "free" energy available anyways.

    Some cars seem to direct the initial waste heat generated after a cold start much more quickly to the passenger compartment than others, however.
  • Passenger comfort was primarily what I was thinking of. Just a small electric heating element somewhere in the duct work. It could sense the temperature of the heater core and shut off when the coolant reached a predetermined temperature. Basically it would eliminate those few miserable
    moments before the engine warms up.
         They've got heated mirrors, heated seats, heated steering wheels and Ford used to have the instaclear windshield, so this just seemed like the next logical step.
         At work people start their cars and let them idle for at least ten minutes to warm the cars. The gas saving I was thinking of would come from less warm up time. Just a thought.
