I’m writing this because it seems no one else in the world will do it. I am very particular about changing my own oil in my cars. First of all because I can do it cheaper than anyone else, secondly it only takes about 15 minutes which is less time than it takes at some places, and thirdly because I trust myself to do it correctly. When I was ready to change the oil in my new ‘05 Chevy Cobalt I discovered that the Cobalt uses an oil filter cartridge instead of the normal oil filter canister. This was new to me and so I went searching on the internet to find out where it goes and how to change it. Guess what, I found nothing. After going through the trouble of trying to figure it out myself I decided to help out my fellow Cobalt owners.

Where does the filter go?
For those of you that already know how to change your oil, let me tell you quick. You can find the filter under the hood of the car. Pull the oil cap off, pull up on the big plactic cover that sits over the engine and you will see the canister where the filter goes. It hangs directly off the side of the engine closest to the front of the car. You’ll be able to tell because it has a large, black plastic top that you have to take off to get to the filter. Thats it!.

For those of you that don’t know how to change your oil, or need a reminder I am writing this small step by step guide to changing your oil in the Chevrolet Cobalt:

How to change the oil in my Cobalt
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. For me, I went about 7,500 miles before I had to change my oil.

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.

9. Clean-up Once you are finished you need to take your used oil to a place that accepts old oil. Do not dump it! Oil contaminates the soil and the water supply so you need to dispose of it properly.

This should be about it. It will only take you about 15 to 20 minutes to complete the whole process.

The next step is resetting your computer. If you need to know how to do that you can view my detailed description: “How To Reset The Computer On Your Chevrolet Cobalt”

UPDATE: Here is an added note by Thomas Witt who e-mailed me some inside info. I haven’t tried this myself since I sold my Cobalt a while back, but you can give it try:

“I found that if you turn your key to ACC (without turning the engine over) you can press the “”"I”"”" button to see the oil setting % and then press the gas pedal three times. This will set the oil setting back to 100%. This info comes from the dealership. They forgot to reset mine so I called them. They told me how they reset Chevy cars which works on most of the later models.”

Thanks so much for this guide. I myself had trouble also until I came across this site. I would have never thought to remove the plastic cover after removing the oil cap. So thanks again.

Thank you my friend. Your time and effort in writing this page is very much appreciated by my son who was attempting today to change the oil in his girl friend’s ‘06 Cobalt. He also was confused and called his father to find out where in the world the oil filter was. To a 50 year old that has changed oil in more cars than I care to remember, mine and for others, this was a new one to me also. Went on the web to attempt to find out what was going on with this engine. Thank you. By your info on the page side, I see you are engaged. Please accept our well wishes for a long and happy life together with your bride.

Fabulous! I couldn’t find that oil filter until I read this. It never occured to me to look under the hood! I kept looking for it under the car. Thanks!

THANK YOU! you don’t know how troubling it is to be stuck on a saturday before a long trip, no mechanic to talk to, with your old oil in a pan and no idea how to change the filter! Thank you!

Thanks alot! I always change my own oil for exactly the same reasons as you. When I bought the filter and found that it was different I thought I would have no problem locating where it would go… Now here I am with the oil drained out and looking on the internet for answers on where the new filter goes. Thank’s for thinking of others and putting this one here!

Thanks from me also. I can’t believe that chevy doesn’t give a hint as to how to do this! Thus must want to drive everyone to the dealership.

BOB, I had the same problem with my ramps, so I put a 2×6 up to each of the tires and then the ramps up to the 2×6’s so that when I went forward on the 2×6’s the car raised up a little, this worked well. Good Luck!

Thank you!!!! Like all the other’s that have been doing their own work for years, the oil filter thing was a complete surprise. I just hope my starter still works after I thought that was the filter housing…. I have my own lift and I searched every inch under that car. Great job!

March 7th, 2006 at 2:11 pm

I made the same mistake. I thought that the little starter was where the filter goes and I unscrewed it only to find the starter coil. They give you no direction whatsoever in the owners manual.

Thanks for the info. My daughters boyfriend asked me to change his oil. I looked over and under the engine for the oil filter. I told him I can’t change the oil if I can’t find the filter. He told me about your article and wala! Of course this could have all been avoided if the idiots at G.M. had told you this in the owners manual. Thanks again.

how do you put the rear seats down in 06 cobalt ?

April 18th, 2006 at 1:29 am
 16 

You may have figured it out by now, but in order to put the back seats down in the Cobalt you have to open the trunk and at the top of the truck there are levers that you pull back which unlatches the seat. Then you go around and pull it down. It’s kind of a pain really.

Thanks! A friend asked me to perform the 60K checkup on his girlfriend’s Cavalier. Needless to say, I was a little puzzled when I saw the filter element at the parts store. Thanks to your article, I had no problem locating the filter element cap. Such a great innovation, too! Hope other carmakers will make this a standard practice someday. Thanks again for the assistance!

Hello, I was wondering how do you change the oil filter on the Chevy Cobalt. Because I was going to change my grilfriend oil on her Cobalt and I couldn’t located it. How do you reset the computer too. My girlfriend lost the manual. So if you could please email me back that would be great thanks. Carlos

I wish i had looked at this article about 4 hours ago. My girlfriend asked me to change the oil in her 2005 Cobalt and i said sure no problem. I have changed oil in every kind of vehicle you can think of but this thing gave me a fit. When i picked up the filter i was puzzled because id never changed a filter quite like that. I was used to the screw on type. I figured it would be no problem and went ahead and drained my old oil out. Then i began looking for the filter under the car, under the hood. I unscrewed the bolts to the starter thinking the filter went in there and i tried to consult the owners manual but it didnt mention anything about the oil filter. Needless to say i wasted a lot of time and felt like a complete idiot looking for that filter.

Thanks for writing this article…my dad has been outside swearing because he couldnt find the filter…good thing I found your information. I already hated GM now I really do, they cant even put that in their manual! Thanks again! By the way does anyone elses cobalt rattle like crazy when driving, GM doesnt know what the problem is and im begining to get really angry! Thanks

thanks a million i change my oil in my vehicals for the same reason you do. i just bought my colbalt 2 days ago. i needed a oil change in my silverado went and bought my supplies for it, and also checked out the oil filter i needed for my colbalt (out of curiosity). the cartarage was a new thing to me but i figured id figure it out when the time came. i did take a quick peek under the car i figured the cartarage canister was there behind the oil pan (i didnt put the car up on ramps since its brand new).im glad i came across this site your are going to save me some time looking for the cartarage holder. when i was looking for oil filters i did see a oversize socket that stated it was for my colbalt canister. i figure ill purchase that when i need a oil change it was 9 bucks for the socket. again thanks a million

Just have to say thanks for this info too - the manual to my HHR of course doesn’t point out where the filter is - when I went to the parts store with the part number and grabbed the box - I was totally confused when I saw it was just the inner cartridge…!

Thanks again.

I believe its the same way for a 2005 chevy cavalier becuase each step correspond with the structure of the oil filter and oil pan. Which was at one point confusing to me. Thanx I needed this one….

Thanks for your help. I certainly would not have figured it out on my own. This is an example of Gm engineering at its best. Completely change the type and location of the oil filter and never mind making any mention of it in the owners manual. I makes wonder why I keep trying to “buy American”

Just big thank you. I went out there to change the sons 2006 Cobalts oil and for the life of me couldn’t find the oil filter. Never happened to me before and I’ve changed them all from 1960 VW’s (wire screen) to 2002 PT Cruisers.

Thank you : You just confirmed what I thought .. I found the filter .. when I tried to pull it will not come out . I see clips on the bottom of the filter holding it . Do I just pull hard to remove or what? Thank you again ….

You should be able to just pull it right out of there.

Hi,
Just wanted to say thanks from my Dad. He, like you pride’s himself on changing the oil on his cars. And just like you didn’t have a clue how
to do it on the Cobalt. On a whim I just googled
“how to change the oil on a Cobalt” and your site came up. He was thrilled to get the info and successfully changed the oil on his Cobalt this weekend. It was very generous of you to share this information. It would have killed him to have to take it to the dealer to have his oil changed.
Thanks again,
Debbie & Papa

Thanks for your site, I have to admit this was the first time I’ve ever changed oil in my own car, and it was quite the experience….
After doing everything right, I forgot to pull the plug on the brand new oil pan, and it went everywhere on the brand new garage floor… whoops.
After that the filter was accomplished with a pipe wrench borrowed from a neighbor. I am going to buy some tools, but needless to say, I will never mess up changing my oil again ;)

I don’t have my book handy. But I think what you need to do is shut the engine off and turn the key to the on position. Then press both the buttons and hold them down until it goes into the menu. Then you flip through the menu until it says “oil reset?” and then you hit the enter button. If I remember correctly I think that is it.

Thank You so much! Sometimes I think they change the standard norm of an oil change, just to make it hard for the home mechanic, to deter us from doing it ourselves, so we are more inclined to take it to the dealer, where they charge you more, and try and talk you into a million other things, and you end up walking out with a $350 dollar oil change! Thanks again!

Thank you so much. I needed instructions on how to change the oil on my gf’s 2005 cobalt. My car (2006 mazda 3) has the same type of filter thing. I wasn’t aware that her car did also. I very much appreciate the time and effort you spent into doing this and making this write up for everyone.

You are well appreciated.

Thank you so much for the instructions, they could not have been more straightforward!

I had a small problem getting the oil filter off because I did not have a socket big enough, but thankfully my friend had one in his van!

I just want to say thanks for the tips on where the filter is. This whole process works for the 2008 model as well. Except for the filter cap you will need a 1 1/4 in. box end wrench or the special ecotech 1 1/4 in. socket. A regular socket is to tall and will get caught on the intake. NO OPEN WRENCHES OR ADJUSTABLE WRENCHES. They will strip the cap corners and then your in a pickle. The plastic would be pretty easily damaged.

Thanx again.

Renie. Sorry I never responded. I’ve not had this cobalt for awhile so I don’t remember what type of oil it uses. That info should be on the oil cap or in the vehicle manual.

Thanks; this site has been a wonderful help. My niece is the one who owns the cobalt. When I went to change the oil for her I was mad ad Chevy; thinking they are just doing this so you have to take it into the dealership. Now I can do this and will save some bucks. :wink:

Thank you! Don’t forget that the cap for the oil cartridge has to be tightened to a specific torque, check the manual. Also be careful as the nut that is “formed” on this cap can crack if tightened to tight, creating a seeping oil leek. and a messy one at that because of it’s top location. As for the person wondering how to get the cobalt onto ramps due to the fender, use 2×4s stepped up, one, and then 2, to clear the fender for the ramp. The first board on the ground the 2 on the ramp, kinda tricky but works… ramps must be secure and don’t forget to put them back when done if you remove them or you will leave your bumper on the ramps…
