Starting and running in the engine after a major overhaul [Toyota RAV4 XA10]

Fill with engine oil and coolant.

Remove the spark plugs from the engine and disconnect the electrical connector supplying voltage to the fuel pump.

Use the starter to turn the engine crankshaft until the oil pressure warning light goes out.

Screw in the spark plugs and connect the electrical connector supplying voltage to the fuel pump.

Start the engine. The engine may take longer to start as it takes time to build up pressure in the fuel system.

Warm up the engine to operating temperature. As the engine warms up, watch closely for any oil, fuel or coolant leaks. Unusual odors and smoke may appear from parts exposed to high temperatures due to the burning of residual oil.

Stop the engine and check the engine oil and coolant levels, topping up if necessary.

If new pistons, piston rings, main and connecting rod bearings were installed, the engine must be run in for the first 800 km. During the break-in period, do not operate the vehicle at full throttle or at too low a speed in any gear.
