Starting the engine after repair and running-in (Chevrolet Tahoe 1)

1. After completing assembly, double check the oil and coolant levels.

2. With the spark plugs removed and the ignition system turned off, turn the crankshaft until the oil pressure indicator light goes out.

3. Screw in the spark plugs, put on the high-voltage wire tips and connect the ignition system.

4. Start the engine. The engine should start immediately.

5. Warm up the engine, carefully monitoring for oil or coolant leaks.

6. Stop the engine and check the oil and coolant levels.

7. Accelerate the car from 50 km/h to 90 km/h, release the throttle pedal, braking the car with the engine to 50 km/h. Repeat the cycle 10-12 times. This will allow the piston rings to become accustomed to the cylinder walls. Check the oil and fluid levels again.

8. Take a 800 km trip without putting the engine under heavy load (move at low speed), periodically checking the oil level. Increased oil consumption is possible during the running-in period.

9. After running 800-1000 km, change the oil and oil filter.

10. For the next few hundred kilometers, drive the car in a normal mode, avoiding too much or too little load.

11. After 3300 km of running, change the oil and oil filter again, after which the engine is considered to have been run in.
