Difference between 5664 & 5665 Kit

Both Generac maintenance kits 5664 & 5665 are listed for 20Kw 999cc Air cooled engine, and the contents are similar, but with difference in price $20.00 & S19.39 -- Why?
Asked by: pbukhari
The 5664 kit is for the generators with the 760cc and 990cc engines. The 5665 kit is the correct kit for the generator with the 999cc engine. Servicing the generator is an easy DIY project if you go slow and read the provided instructions (the instructions are very clear and easily understood). Besides gaining a better understanding of your equipment and the satisfaction of Doing It Yourself, you save the price of a service call.

I have a Generac 14kW air cooled generator, will this work

Asked by: Bob16
As this scheduled maintenance kit is manufactured for use on our 20,000 watt automatic standby generators featuring a 999cc engine, we would not recommend attempting to utilize it on a 14kw automatic standby generator. To ensure that you are able to acquire the appropriate maintenance kit for your personal unit, please contact us directly at 888-GENERAC (436-3722) with the serial number of your personal product.

20 KW Generac, what typ of oil and how many quarts do you need?

Oil type,
Asked by: Drew
Depends on the climate in the location you have it installed. I live in Md and my installer recommends 5w 30 synthetic oil. Since you live in a warmer climate, you could probably use 10w30. Just call up any random Generac certified installer in your area and ask them the question. It will not cost you anything. You will need 1.7 quarts of oil.

where do you purchase oil filters for 20kw models

Asked by: Anonymous
Several places online. But I have found that the Home Depot maintenance kit ($20 with free site to store shipping) is by far the best value because you get the air filter and spark plugs also. I have yet to find just the filter by itself. The Home Depot kit comes with the oils filter that is from Generac.

Scheduled Maintenance Kit for Air Cooled 20,000-Watt 999cc Engine Generators is rated 4.3 out of 5 by 28.
Rated 2 out of 5 by from DOES NOT fit the Generac model #6244, 20kW air-cooled generator This kit DOES NOT fit the Generac model #6244, 20kW air-cooled generator. This kit comes with a round filter, the 6244 requires a square automotive type filter. I found it to be a bit overpriced since you can buy all of these items separately for a little over half of the cost. The filters were basically FRAM air and oil filters that were made for Generac with their name and logo and Champion spark plugs.
