Caution: When starting the engine for the first time after repair, have a fire extinguisher on hand.
1. After installing the engine on the vehicle, check the engine oil and coolant levels.
2. Remove the spark plugs from the engine. Disconnect the ignition system and the fuel pump (to do this, remove the C/OPN relay from the fuse/relay box in the engine compartment). After this, crank the engine until the oil pressure indicator appears on the corresponding gauge, or until the corresponding indicator lamp goes out.
3. Install the spark plugs and ignition coils and connect the fuel pump.
4. Start the engine. It may take some time for the fuel system to build up pressure, but the engine should start without any problems.
5. After starting the engine, warm it up to normal operating temperature. While warming up the engine, check thoroughly for fuel, oil and coolant leaks.
6. Turn off the engine and check the engine oil and coolant levels again.
7. Take the car to a section of road with minimal traffic, accelerate from 50 to 80 km/h, and then allow the car to slow down to 50 km/h with the throttle fully closed. Repeat the procedure 10-12 times. This will apply load to the piston rings and force them to assume the correct position relative to the cylinder bores. Again, weld for coolant and oil leaks.
8. Operate the car in a gentle mode for the first 800 km (without prolonged movement at high speed). Check the oil level regularly. Increased oil consumption during the break-in period is normal.
9. After approximately 800-1000 km, change the engine oil and oil filter.
10. For the next few hundred kilometers, you can operate the car as usual. Do not neglect its maintenance.
11. After 3000 km of run, change the engine oil and oil filter again. After this, the engine running-in can be considered complete.
