MAINTENANCE SCHEDULE — 6.7L CUMMINS® DIESEL ENGINE
CAUTION!
Failure to perform the required maintenance items may result in damage to the
vehicle.
At Each Stop For Fuel
• Check the engine oil level at least 30 minutes after a fully warmed engine is shut off. Checking the oil level while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when the level is at or below the ADD
or MIN mark.
Once A Month
• Inspect the batteries, and clean and tighten the terminals as required.
• Check the fluid levels of the coolant reservoir, brake master cylinder, and automatic transmission (if equipped), and add as needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Check the coolant level, hoses, and clamps.
• Lubricate outer tie rod ends.
Inspection and service should also be performed anytime a malfunction is observed
or suspected. Retain all receipts.
