Engine — first start after repair (Opel Astra F)

After installing the engine on the vehicle, check the engine oil and coolant levels.

After removing the spark plugs and disconnecting the low voltage wire from the coil, crank the crankshaft with the starter until the oil pressure indicator light goes out. This may take a few seconds as the new filter fills with oil.

Install the spark plugs and connect the high tension wires.

Start the engine, keeping in mind that this may take a little longer than usual as fuel is pumped into the engine. If a new camshaft has been installed on a single camshaft engine, pay special attention to the running-in period.

With the engine idling, check for fuel, coolant, and oil leaks. If necessary, check for leaks in the power steering circuit and/or automatic transmission hose connections. Do not be alarmed if there are any strange odors or small amounts of smoke from hot engine surfaces.

Let the engine run at idle until the radiator begins to receive hot coolant through the upper radiator hose, which will indicate the normal operating temperature of the engine, then check the ignition setting and. if necessary, adjust the engine speed at idle and the fuel mixture (its quality).

Stop the engine; if the cylinder head was removed, tighten the bolts as required (step 5).

Allow the engine to cool, then recheck the oil and coolant levels and top up if necessary.

If new pistons or bearings are installed, the engine should be run in at reduced speeds and loads for approximately 800 km. Do not open the throttle fully or run the engine in one gear during this period. After the break-in period is complete, it is a good idea to change the engine oil.
