#2 of 138 Cooling fan??
Mar 18, 2006 (9:30 am)
I just picked my 2006 Cobalt LTZ, and I noticed that the electric coolant fan runs at startup even though the water temp. is about 75 degrees! Is this normal? It seems strange to me. Can anyone PLEASE advise me? Also, where is the darn oil filter located at?? I have a 2.2 eng.,sedan. Thank you... Harvey

If you have the HVAC controls set to defrost and it's warm enough the AC will turn on and with it the fan. Otherwise fan shouldn't run at start up. The oil filter is under that plastic shroud on driver's side of engine. You're looking for a ~3 inch black plastic cap with a large hexagon nut on top. The cartridge filter is underneath.

Hello, NO I did not have the defroster or the AC controls on. The heat was set to warm! When I backed out into the driveway, I checked the fan again and it was off!! Very strange for sure, but thanks for the help and also for your help with the oil filter.. Take care.

I called the service dept. about that fan...He said that the fan MAY go on in my gararge because its 70 to 75 degrees in there. My furnace is in there also. Does that make sense or am I crazy??!! I've been a mechanic all my life and I think the fan should come on at about 195 dergees or so, which it reaches very quickly!!
Any thoughts? I DO love the car though!!! WOW!!

I could be talkin' through my hat, but I believe the oil filter is in a canister on the front right side of the engine as you are facing it. I have a 2004 Cavalier, and since the Cobalt shares the same engine, a good guess would be the same location. One of the easiest oil changes you will ever do!! Just remove the top cover, and be sure to install the new filter in the same manner as removing the old.

Thank you Johnny for the advise...Yes I think you are right about the oil filter, as others have told me the same thing. Now I just gotta figure out why the coolant fan comes on at low temps or at startup. The dealer says thats normal???!!!! Hmmmm! Well take care.

How To Change The Oil In Your Chevrolet Cobalt
When your ready to change the oil in your Chevy Cobalt you'll discover that the Cobalt uses an oil filter cartridge instead of the normal oil filter canister that you screw on.
1. When Do I Change My Oil? While many times the manufacturer recommends changing your oil every 3,000 miles or so, the Cobalt actually has a computer that uses a working algorithm to calculate the use of your oil based on how much you drive, how fast you drive, and how quickly you accelerate. With the computer you only need to change your oil when the "Change Oil Soon" messages appears on your message board. I myself change my oil every 3,000 miles or 4 months reguardless of what the oil life is.
2. What materials do I need? You will need 5 Quarts of 5W/30, an oil filter (cartridge) for your car, a #15 metric wrench, a tool to take loose the oil filter plug, old rags, an oil pan, and a funnel.
3. Make sure the engine is warm Get all of your tools together, purchase the oil and filter, and then drive your car around awhile to get your engine warm. If your heater is blowing out hot air then you are good. This gets your engine oil thinned out which will make it easier to drain.
4. Drain your oil Put your drain pan under the car's oil pan and loosen the bolt using the metric wrench. Just loosen the bolt first, unless you wish to have your hand drenched in burning hot oil (remember, you just drove it around to get it hot). Once you loosen the bolt with the wrench, you can continue to turn the bolt with your fingers, holding it tight until your ready to pull the plug out and let it drain. Make sure your aim is correct and you pull it quick or you could get oil all over the floor, your hand, your face, or anything else that is in the way. Remember you just drained the oil out of your car, so good luck getting to the emergency room if you burn your face off.
5. Change your filter While you let your oil drain, go ahead and get under the hood of the car. Once you pull the oil cap off you can pull off the big plastic cover that sits over the engine. It isn't bolted down, so all you have to do is lift up on it and it will come right off. Once the plastic cover is removed, you will be able to see the canister where the filter goes. It's silver, it hangs directly off the side of the engine, closest to the front of the car, and the top of it has a black, plastic plug that you can remove by turning it with a socket or a wrench, but let me tell you it takes a big one. If you don't have a socket that fits, then you can be creative and try to get it loosened another way. Be careful, don't ruin or bust the plastic top. Once you get it unscrewed, just lift up on the black plug and the filter will come right out with it. Put the new filter in. Make sure the filter canister is empty, and then put it back into the canister and tighten it up.
6. Put your oil plug back in and fill it up Once it's finished draining, put your oil plug back in and tighten it. Now that your filter is in and your oil plug is in, your next step is to put your new oil in the engine. This is where the funnel comes in handy.
7. Start it up and check for leaks Once you have filled your car with the proper amount of oil you need to start it up and make sure it isn't leaking or dripping from the oil plug or from the filter canister. If everything is tight you shouldn't have a problem.
8. Reset your computer As soon as your oil is changed you need to reset your computer. Read the manual on your Cobalt to figure it out... it is easy.
