MAINTENANCE MAINTENANCE The following is intended as a guide for establishing preventive maintenance intervals. The recommendations given should be followed as closely as possible to obtain long life and optimum performance from your engine. Maintenance intervals indicated are time (hours) of actual operation. NOTICE: Failure to check and maintain SCA (supplemental coolant additive) levels at required concentrations will result in severe damage (corrosion) to the engine cooling system and related components. Coolant must be inhibited with the recommended SCAs listed in this guide. Refer to “How to Select Coolant”.
In addition, the engine can be equipped with a coolant filter/inhibitor system as an installed option or as an after-sale item. The intervals shown apply only to the maintenance functions described. These functions should be coordinated with other regularly scheduled maintenance.
