REMOVAL

NOTE: It is normal for the water pump to weep a small amount of coolant from the weep hole (black stain on water pump body). Do not replace the water pump if this condition exists. Replace the water pump if a heavy deposit or a steady flow of green-brown engine coolant is evident on the water pump body from the weep hole (shaft seal failure). Be sure to perform a thorough analysis before replacing water pump.

1. Drain Cooling System in suitable container.
2. Remove Accessory Drive Belt.
