2. Remove the spark plugs. On models with a distributor, shut off the ignition system by disconnecting the ignition coil high voltage wire from the distributor cap and grounding it to the cylinder block. Use a jumper or similar wire to make a good connection. On models with a static ignition system (without distributor) Disable the system by disconnecting the low voltage connector from the high voltage ignition coil.
3. Turn the engine over with the starter until the oil pressure warning light comes on. Install the spark plugs and connect the high voltage wires to them. Connect all previously disconnected wires (point 2).

4. Disconnect the wiring from the fuel cutoff valve on the fuel pump, then crank the engine with the starter until the oil pressure warning light comes on. Connect the wire to the fuel cut-off valve.
5. Bleed the fuel system.
6. Press the gas pedal all the way, turn the ignition key and wait until the preheating control lamp lights up.

7. Start the engine, remembering that it will take a little longer than usual, because. the components of the power system will initially be empty.
8. With the engine running at idle, check for signs of fuel, oil, or coolant leaks. Do not worry about the smell of burning and smoke coming from the warming up components in the engine compartment - this is a consequence of oil burnout and assembly grease. If hydraulic tappets were removed during the engine repair, at first the noise level of the valve mechanism will be slightly increased, however, after complete circulation of oil in the engine and after the pressure rises to a normal value, the noise intensity should decrease to normal.
9. Keep the engine idling until the upper radiator hose feels hot to the touch, check that the engine idle is stable and the engine speed is normal, then turn off the engine.
10. After a few minutes, check the oil and coolant levels again, top up if necessary.
11. If the cylinder head bolts were tightened according to the scheme proposed in the Manual, there is no need to check their tightening forces at this stage.
12. If individual components such as pistons, piston rings or crankshaft bearings were replaced during the overhaul, the engine must be run-in during the first 800 km of run. At the same time, you should not overload it with driving at wide open throttle, driving in low gear. Upon completion of the break-in, it is recommended to change the engine oil and oil filter.
