Do it yourself so easy..!!
I was not going to pay a service charge for the maintenance..! I contacted GENERAC and was told we can do it ourselves so long that we have the receipts..!! Think is the response: Thank you for contacting Generac Power Systems, Inc. My name is Cristina, and I will be assisting you today.  You can certainly choose to perform your own maintenance if you'd like. Maintenance is customers responsibility unless you hire someone to do it for you. You will just want to make sure that whoever is doing your maintenance not only knows what they are doing but also keeps a record of the maintenance work being done. Receipts, documentation, things of that matter. It may be needed down the line if you ever need warranty work. You can also choose to go with another local dealer if you'd prefer for maintenance. I have attached our dealer locator below. Please let us know if there is anything else we can assist with.

    Thanks to another review I was able to confirm these parts are the exact OEM parts our 22kw generac was equipped with.
    The correct generac oil filter which has the diameter required for the generac cold weather heater. The generac air filter which is the exact size. (The knock off is a bit too big). The correct Champion spark plugs.

    5.0 out of 5 stars 22kw Generac standby generator
    Reviewed in Canada on December 18, 2023
    Verified Purchase
    We had our generator installed in December 2022 which is a late install for Canadian (Quebec) standards however the shortage of labour and all the regular pandemic excuses were the culprit. The one year cycle came around quicker than anticipated and our generator was showing a green/yellow light (December 2023) instead of the solid green. The computer no doubt triggered the 1 year, 1st maintenance cycle which I absolutely wanted to get done before the harsh Winter settled in.
    I called the authorized Generac dealer for the Montreal area and the representative told me that it was a 4 month wait and the pricing was 4 hours minimum at $150 + taxes per hour + kilometers charged to and from their shop (this worked out to about about $140 + taxes in my case). In total I was looking at $740 + taxes without any other "surprises".
    Skeptical about the extremely low cost of this package, I actually called Generac and confirmed all the part numbers to the representative... "all good" she said, they match everything needed for our generator.
    鶹 Prime delivered this the next day and I performed the required maintenance within about 40 minutes which is way longer than what it should have taken simply because I completely familiarized myself with the generator and the onboard electronic menu. Otherwise, anyone should be able to get this done in about 25 minutes. The longest part is waiting for all of the oil to drain from the narrow passage drain tube. Just saved ourselves about $700 and avoided some indifferent and careless technician showing up to try and convince me that it was worth $750.

    Verified Purchase
    Perfect maintenance package for my GENERAC whole-house generator...all the items necessary were included and fit perfectly. With so many free YouTube videos online that walk you step by step through the maintenance, I don't know why everyone wouldn't buy this set and save a ton of money. I did buy the oil and a new battery locally as I did a major maintenance job, not just the annual maintenance. I will purchase this package yearly.

    Everything was very easy to install and made for my Generac 24KW It been about 3 weeks since I installed the maintenance kit and have had no problems. The system is 3 years old runs perfectly. The maintenance schedule is based on hours run I believe I have about 40 hours on the system which is an indication of low power outages. I do the maintenance annually just because I do not want any problems. This is my fourth Generac over 25 years as I move frequently and do not want my family to be burdened with power outages.

    5.0 out of 5 stars Easy Peasey! Some tips for first timers
    Reviewed in the United States on June 3, 2024
    Verified Purchase
    I decided to do this myself for the first time. I have a Generac Guardian Series 22KW 999 cc Engine, Model No. GOO70422. So 7042 in the list below.

    If the first 4 numbers of your Generator's model number begins with: 6055, 6098, 6103, 6244, 6250, 6258, 6551, 6279, 7034,7035,7036, 7037, 7038, 7039, 7040, 7041, 7042, 7043, 7045, 7048, 7049, 7077, 7078, 7141, 7142, 7145, 7146, 7163, 7173, 7174, 7175, 7176, 7177, 7178, 7189, 7209, 7210, 7218, 7219, 7291 then this is the right kit for you!

    This kit consists of:
    1 Oil Filter part no.: 070185E
    1 Air Filter part no.: OJ8478
    2 Spark Plugs part no.: RC12YC (which is the Champion equivalent of Generac part no.: OGO767A)

    I recommend doing the Spark Plugs and Air Filter before you do the oil change since the motor doesn’t need to be hot for that part of the job and is more comfortable to work on cool. Especially in the Summer!

    Spark Plugs: The Champion RC12YC spark plugs come pre-gapped from the factory at .38 so you’ll need to widen the gap slightly to get it to .40 as recommended by Generac. If you are using a ramp style plug gap gauge you will want the center of the electrode to be centered on the .40 line on the gauge. You’ll need a 5/8 Spark Plug socket and a Torque Wrench. Plugs should be torqued to 25 Newton Meters.

    Note: I needed only the wrench and socket to remove the plugs. I did not need any flexible extensions as some did. Flexible Extensions can cause the Torque wrench to get inaccurate readings so I would not recommend using one.

    Air Filter: The Air Filter housing has one clip that flips up from underneath the front lip. There are two tabs on the backside that stick through two square shaped openings on the back and you’ll need to pull backwards on the housing until they pop through the square shaped openings, thus releasing the housing. The rubber hose simply slips off the hard plastic connector it is connected to.

    Oil Change: Run the motor (push the “manual” button) for about 5 minutes or so until warm and then push “Stop” to shut it down. Unscrew the cap from the flexible drain tube, and drain the oil into a container that you can later take to the auto parts store for recycling. I used a disposable Tupperware container and then transferred the dirty oil to an empty Orange Juice bottle with a screw cap. I put the old oil Filter in a ziplock baggie.

    Next, replace the Oil Filter. This is the messiest part of the job. I highly recommend unscrewing it by hand with several layers of paper towels under the filter and surrounding the entire filter itself as you unscrew it (lefty loosey). Put some clean oil on the rubber gasket of the new one and hand tighten until gasket touches and then tighten an additional 3/4 turn. Add 1.9 quarts of oil.

    Note: .9 quarts will leave approximately 3.2 ounces of oil in the bottle (Mobil One Oil has ounce markings right on the bottle). The oil dipstick has 2 holes in it. The oil level should be just above the upper hole in the dipstick (the oil is difficult to see but If you hold the dipstick at a slight angle to the light it’s easier). When full, replace the drain hose cap and put it back in the holder.

    Manually start the Generator and check for leaks. Lastly put the Generator back into “Auto” mode et Voila! You’re done for another 2 years!

    Note: You really only HAVE to change the Plugs and Air Filter every 4 years (they are schedule B items) but it’s so cheap and easy to do I do it every two years along with the other Schedule A items just for the sake of overkill. I enjoy overkill in case you haven’t noticed. 😉☝️

    This job was MUCH easier than I expected and in my case it saved me $350.00 (I live in California) and the hassle of having to be home to meet a Technician.

    Take your time and enjoy the process. There’s no better feeling than doing something for yourself and it’s nice to save a few bucks too! Good luck! 😎
