Every 150 hours or 120 days of operation
Annually, or as required in dusty environments
Every 2500 hrs or As Required
Every 200 hours, or every 100 hours in dusty environment
Prior to any service or maintenance activity

Note 1 = PSI requires the use of coolant meeting GM specification GM6277M. When used, this coolant change interval is 5,000 hours or 5 years (whichever occurs first).
Changing of coolant types (typically indicated by color) and mixing of coolants is not allowed as this can result in a loss of coolant protection during the engine life. Consult the
OEM for the correct replacement interval if you use coolant other than GM6277M
