Change the engine oil and filter as indicated by the instru-ment cluster display, and perform the services listed in thescheduled maintenance chart.
As required
Replace the engine-mounted and frame-mounted fuelfilters.Every 15,000 mi(24,000 km), six months or600 engine hours
Inspect the coolant concentration, freeze-point protectionand additive, corrosion inhibitor strength. Add coolantadditive if necessary.
Every 30,000 mi(48,000 km) or 1200 enginehours
Flush and refill the coolant. Do not add coolant additive.Every 60,000 mi(96,000 km) or 2400engine hours
Note:When adding coolant additive, do not exceed the specified maximum of 47 fl oz(1.4 L) for the engine and 20 fl oz (473 ml) for the secondary cooling system. Operating theengine with excessive coolant additive may cause overheating which could lead to severe,permanent engine damage.
Note:After the initial coolant flush and fill at 60,000 mi (96,000 km) or 2400 enginehours, flush and fill every 45,000 mi (72,000 km) or 1800 engine hours thereafter.
