- Tighten the water pump cover bolt with the new seal ring to 8 Nm (5.9 lbf ft).
- Refill the Cooling System:
- Slowly fill the radiator with the recommended coolant (see your owner's manual for type and capacity).
- To avoid air pockets, fill until liquid reaches the radiator neck.
- Bleed the System:
- Loosen the cylinder head bleeder screw until coolant flows free of bubbles, then tighten to 8 Nm (5.9 lbf ft).
- Final Checks:
- Top off coolant if needed, then reinstall and tighten the radiator cap securely.
- Start the engine and let it idle briefly, checking for leaks and rechecking level after the engine cools.
- Dispose of used coolant responsiblynever pour it on the ground or down a drain.
