Attention! Have a fire extinguisher handy when starting the engine for the first time.
1. When the engine is installed in the vehicle, double check the oil and coolant levels.
2. After removing the spark plugs from the engine and removing the fuse for the electronic control unit, rotate the engine crankshaft with the starter until the oil pressure is registered on the pressure gauge and the oil pressure control lamp goes out.
3. Screw in the spark plugs, put on the spark plug wires, insert the fuse for the electronic control unit.
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, check again the timing and correct connection of the spark plug wires.
5. After starting the engine, allow it to warm up to normal operating temperature. While the engine is warming up, be careful not to leak fuel, oil or coolant.
6. Stop the engine and recheck the engine oil and coolant levels.
7. Drive in an area with light traffic, accelerate to full throttle from 30 to 50 mph, then decelerate to 30 mph by closing the throttle (releasing the pedal "gas") Repeat this procedure 10-12 times. This will give the pistons a load and cause them to properly fit against the cylinder walls. Check again for oil and coolant leaks.
8. Drive your first 500 miles "soft" (not 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 "eating butter".
9. Change oil and oil filter after approximately 500-600 miles.
10. Drive the car normally for the first few hundred miles, without overloading the engine.
11. After 2000 miles, change the oil and oil filter again and you can consider that the engine has been broken in.
