2. Oil System Prime: a. The engine should be primed with oil before starting. Install an oil pressure gauge (the existing oil
pressure sensor location at the upper rear of the engine may be used) and disconnect the engine control system (removing
power from the engine control module is generally recommended). Note: Disconnecting only ignition or fuel injector
connectors is not recommended – make sure the control system will not provide ignition or fuel to the engine. b. Once
the engine control system has been disconnected, crank the engine using the starter for 10 seconds and check for oil
pressure. If no pressure is indicated, wait 30 seconds and crank again for 10 seconds. Repeat this process until oil
pressure is indicated on the gauge.
3. Initial Engine Start: Reconnect the engine control system. 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.
4. Engine Warm Up Recommendation: 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.
5. First 30 Mile Break-In Period: 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.
6. Medium Accelerations for Break-In: Run five or six medium throttle (50%) accelerations to about 4000 RPM and back to
idle (0% throttle) in gear.
7. Hard Accelerations for Break-In: Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back
to idle (0% throttle) in gear.
8. Change the Oil and Filter: Replace the oil per the specification in step 1, and replace the filter with a new PF48 AC Delco
oil filter. Inspect the oil and the oil filter for any foreign particles to ensure that the engine is functioning properly.
9. 500 Mile Break-In Period: 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.
10. Change the Oil and Filter After 500 Mile Break-In: Again, inspect the oil and oil filter for any foreign particles to ensure
that the engine is functioning properly.
