Detailed Maintenance Procedures
Follow these structured procedures to ensure thorough maintenance of your Peterbilt diesel engine. Adapt these steps to your specific engine model and operating conditions.
Oil & Filter Change Procedure
- Warm engine to operating temperature
- Turn off engine and wait 10-15 minutes for oil to drain back to pan
- Remove drain plug and drain oil completely
- Replace oil filter(s) and ensure gaskets are properly seated
- Install drain plug with new washer if required
- Fill with manufacturer-specified oil to correct level
- Run engine and check for leaks
- Verify oil level after engine shutdown
Fuel Filter Replacement
- Turn off engine and wait for cooling
- Drain water separator completely
- Remove primary and secondary fuel filters
- Pre-fill new filters with clean diesel fuel
- Lubricate gaskets with clean oil
- Install filters and tighten to specifications
- Prime fuel system according to manufacturer procedure
- Start engine and check for leaks
Cooling System Service
- Ensure engine is cool before beginning
- Remove radiator cap carefully
- Drain cooling system at radiator and block drains
- Flush system with clean water if changing coolant type
