Caution: When starting the engine for the first time, have a fire extinguisher at hand.
1. Once the engine is installed in the vehicle, double check the oil and coolant levels.
2. After removing the spark plugs from the engine and the fuse for the electronic control unit, turn the engine crankshaft with the starter until the oil pressure gauge registers oil pressure and the oil pressure indicator light goes out.
3. Screw in the spark plugs, put on the spark plug wires, insert the ECU fuse.
4. Start the engine. It may take a few seconds for the fuel system to build pressure, but the engine should start without much difficulty.
Note: If the engine does not start, recheck the valve timing and the spark plug wires for proper connection.
5. After starting the engine, allow it to warm up to normal operating temperature. While the engine is warming up, carefully check for fuel, oil and coolant leaks.
6. Stop the engine and recheck the engine oil and coolant levels.
7. Drive in a light traffic area, accelerate to full throttle from 30 to 50 mph, then let the car slow down to 30 mph with the throttle closed (release the gas pedal). Repeat this procedure 10-12 times. This will load the pistons and cause them to seat properly against the cylinder walls. Check again for oil and coolant leaks.
8. Drive the car "softly" for the first 500 miles (without maintaining high speed for long periods of time) and check the oil level regularly. During the break-in period, it sometimes happens that the engine "eats oil".
9. After approximately 500-600 miles, change the oil and oil filter.
10. For the first few hundred miles, drive the car normally, without overloading the engine.
11. After 2000 miles, change the oil and oil filter again and you can consider the engine broken in.
