START-UP AND BREAK-IN PROCEDURES
1. Start the engine and listen for any unusual noises. If no unusual noises are noted, run the engine at approximately 1000
RPM until normal operating temperature is reached.
2. When possible, you should always allow the engine to warm up prior to driving. It is a good practice to allow the oil sump and
water temperature to reach 180°F before towing heavy loads or performing hard acceleration runs.
3. The engine should be driven at varying loads and conditions for the first 30 miles or one hour without wide open throttle
(WOT) or sustained high RPM accelerations.
4. Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
5. Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.
6. Change the oil and filter. Replace the oil and replace the filter with a new AC Delco oil filter. Inspect the oil and the oil filter for
any foreign particles to ensure that the engine is functioning properly.
7. Drive the next 500 miles (12 to 15 engine hours) under normal conditions. Do not run the engine at its maximum rated engine
speed. Also, do not expose the engine to extended periods of high load.
8. Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine is functioning
properly.
