Remove bolts (4). Remove pump inlet elbow (5) from the tube and water pump (3). Remove seal (7).
Remove bolts (6).
Remove bolts (1). Remove water pump (3) from the housing. Note: Do not handle the water pump by the shaft or allow the shaft to support the water pump. Improper handling of the shaft can allow the shaft to contact the ceramic seals in the water pump. This can damage the ceramic seals. Damage to the seals will cause leaks and failure of the water pump.
Remove gasket (2) from the water pump. Remove the O-ring seal from the water pump. Installation Procedure

Tool Part Number Part Description Qty
A 1U-6396 O-Ring Assembly Compound -
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Water pumps may leak as a result of damaged face seals. Relative movement between the shaft and the housing may allow the drive shaft to contact the face seal in the water pump. If contact occurs, the face seal will be damaged, and early hour failures can result.
Install water pump (3) in the reverse order of removal.
Lubricate the O-ring seal on the tube with Tooling (A). Install the O-ring seal on the tube, if necessary.
