UGP-Generac Combo 5658 Maintenance Kit for 4.2L Generators

Keep your compatible liquid-cooled standby generator prepared for reliable operation with this UGP/Generac Combo Maintenance Kit. Designed as a replacement for Generac maintenance kit 5658, it combines a UGP air filter with a genuine Generac oil filter and the additional components needed for routine engine servicing.

Replacing contaminated filters and worn spark plugs helps maintain clean airflow, effective oil filtration, dependable ignition, and consistent engine performance. This kit is designed for select generators equipped with 4.2L engines.

• 1 UGP replacement air filter
• 1 genuine Generac oil filter
• 6 replacement spark plugs

Please Note: Engine oil, coolant, and other service fluids are not included. Purchase the correct fluids separately according to the specifications in the generator owner’s manual.

Maintenance is generally recommended every 200 operating hours or every two years, whichever comes first. More frequent servicing may be necessary after prolonged operation or in dusty, dirty, or otherwise demanding environments.

Always consult the generator owner’s manual for the proper service interval, oil and coolant specifications, fluid capacities, spark-plug gap, and installation procedures. Verify the generator’s model and serial numbers before ordering because 4.2L applications can vary by production series.

This is a mixed-component replacement kit and should not be described as an entirely genuine Generac OEM maintenance kit.

Application note: Generac 5658 is most commonly listed for 48kW generators with 4.2L engines. Some older catalogs associate 4.2L engines with different output ratings, including 35kW and 45kW. To avoid an incorrect listing, use the broader 4.2L title and confirm any 35kW or 45kW application by model and serial number.
