Engine — preparation for starting after overhaul (Opel Omega B2)

1. Make sure the engine oil and coolant levels are correct, everything is connected and there are no tools or rags in the engine compartment.

2. Make sure the ignition is off. Then deactivate the ignition system by disconnecting the wiring connector from the ignition module (see the relevant section), and the fuel system by removing the fuel pump relay from the relay box in the engine compartment (see the relevant section).

3. Crank the engine with the starter until the oil pressure warning light goes out. Check that the ignition is off, then reinstall the relay and connect the wiring connector.

4. Start the engine as usual, but be aware that it may take a little longer than usual.

5. Let the engine idle and check for fuel, water and oil leaks. Don't worry if there is a smell or smoke coming from some parts.

6. If everything is OK, let the engine idle until you feel hot water flowing through the top hose, then turn off the engine.

7. Allow the engine to cool, then recheck the oil and coolant levels (see the relevant section), and bring them up to standard.

8. If new pistons, rings or crankshaft bearings have been installed, the engine needs to be run in. During the first 800 km of travel, do not turn on full throttle or overload it at low speeds. After the run in, it is recommended to change the oil and filter.
