8. Install the expansion tank in the reverse order of removal.
9. Fill the cooling system with liquid (see «Coolant replacement»). Screw on the expansion tank cap, start the engine, check for coolant leaks from the tank hose connections, and warm up the engine at idle to operating temperature to remove air pockets from the system.
