| (1) Approximate quantity listed. (2) On gasoline engines, use an API energy conserving engine oil that is certified for gasoline engines. On diesel engines, use engine oil with API CF-4/SH or CG-4/SH rating for diesel engines. (3) Add this amount of fluid. Start engine and shift transmission through all gears and back to Neutral. Add additional fluid to bring fluid level to the MIN mark on dipstick. Recheck fluid level with transmission at normal operating temperature. Adjust fluid level to MAX mark on dipstick. Approximate drain and refill capacity is 4.0 qts. (3.8L). (4) Quantity may vary by type of oil cooler and oil cooler lines. (5) Verify type of transmission used before servicing. The NV 3500 uses a flywheel housing which is an integral part of the transmission housing. The NV 4500 uses a flywheel housing which is bolted to the front of the transmission and transmission contains a Power Take-Off PTO) cover on passenger's side of transmission.

Severe service is described as long periods of engine idling, frequent short trip operation of less than 5 miles, trailer towing, off-highway operation, snow removal operation, or operating in dusty or excessively hot conditions. (2) Service interval is not available from manufacturer. Use filter minder on top of air cleaner housing to determine condition of air filter. If filter minder is in the Red zone, replace air filter. Reset filter minder by depressing button on top of filter minder. (3) Replace coolant at 36,000 miles or 36 months whichever occurs first. Replace coolant at 36 months regardless of mileage. After first coolant change, replace coolant every 24 months or 30,000 miles thereafter. (4) Monthly interval is not available from manufacturer.
