Generac 5663 – Frequently Asked Questions

1) What exactly comes in the Generac 5663 Guardian maintenance kit?
Generac's 5663 kit ships with an air filter, a pre-cleaner, an oil filter, two spark plugs, a chamois and a maintenance reminder sticker. Engine oil is not in the box, so order oil separately to the grade and quantity your generator's owner manual calls for. Everything together weighs 2.0 lbs.
2) How often should a Guardian standby generator get this service kit?
The recommended interval is every 200 hours of run time or every 2 years, whichever comes first. Generators running in dusty conditions need the filter side serviced more often than that. Because the kit includes a reminder sticker, techs servicing a fleet can date the unit at the time of service and track the next visit off the machine itself.
3) Is the 5663 kit for air-cooled or liquid-cooled Generac standby units?
It is the air-cooled Guardian home standby kit. Guardian air-cooled engines are what this service set is built around, so a liquid-cooled standby unit takes a different kit entirely.
4) Do I need to buy anything else to complete a full service with this kit?
Engine oil is the one thing you have to add. The filters, pre-cleaner and both plugs are in the box, but oil is bought separately and the type and capacity come from the generator's owner manual. Everything else needed for a standard filter-oil-plug service is covered.
5) Why does the Generac 5663 kit include two spark plugs instead of one?
Two plugs because the air-cooled Guardian engines this kit serves are twin-cylinder, one plug per cylinder. Both get replaced together at service, gapped and torqued to the owner manual figures.
6) Can I stock Generac 5663 kits for a portfolio of standby generators across multiple properties?
That is a normal use for it. It is a single standardized part number, model 5663, at 2.0 lbs per kit, so a property manager or facilities buyer can stock one SKU for every air-cooled Guardian on the portfolio and issue the same kit to whoever performs the service. There are no shipping restrictions flagged on it.
7) What is the correct order of operations when servicing a Guardian with this kit?
Shut the generator down completely and let it cool first, and read the unit's manual for its specific procedure. Then swap the air filter and pre-cleaner, change the oil and fit the new oil filter, replace both spark plugs to the manual's gap and torque, and finish by dating the reminder sticker for the next interval.
8) Where is the Generac 5663 maintenance kit made?
United States manufacture. Buyers with domestic-sourcing requirements on MRO purchases can use it on that basis; the kit carries no shipping restrictions.
