    Pull tube out with lever bar.

    STEP 5

    Remove rear o-ring in back of engine block. Clean groove and install new o-ring. Part# 11-53-1-710-048 (Do not install the o-ring that comes on the pipe. It must stay in place on the pipe). Apply a little of the supplied grease to o-ring in rear of block.

    INSTALLING FRONT SEAL

    [Part # AGA-N62-V SEAL]

    (Seal placed on tube for shipping purposes)

    Remove seal by hand from pipe

    Install engine block front seal.

    Flat end of the seal should be facing towards the front of the car when installed in engine block.

    Apply white grease (supplied in the kit) to new seal; fold seal and insert into hole (see drawing on the left for directions).

    Work seal into grove by hand.

    Seal must be completely seated before installing tube. If necessary, push seal in place with a blunt tool (blue nylon tool supplied)

    Start with the tube collapsed. Lube tube on both ends with white grease (supplied in kit). Hold tube into engine block. Insert tube into rear of engine block. Turn tube so it expands, as front of the tube enters seal, observe front seal with mirror from water pump side as the tube goes into seal. Sealcannot be pinched. If seal pushes out, collapse tube a bit, turn tube without expanding a few turns and then continue expanding until seal can no longer be seen from water pump side.

    STEP 9

    Tighten tube by hand until it has tension on front and on the rear o-ring.

    How should the Coolant Pipe be installed?

    The tapered portion of the coolant pipe should be facing the cylinder head. Make sure the pipe sits evenly in the pocket and extends all the way to the water pump. Extend the coolant pipe until the seal is no longer visible. The coolant pipe can be hand-tightened until secure.

    Do you have to remove the water pump when installing the your coolant pipe?

    No, you are not required to remove the water pump when replacing the coolant pipe in an N62, N62-TU or N73 engine. However, removing the water pump will help give you more visibility so that you can ensure that your seal is sitting properly in the vehicle.

    What is the average repair time for the Coolant pipe replacement repair if I use your part?

    The N62 Coolant Pipe repair takes approximately 8-10 Hours to complete (10 hour estimate includes the water pipe removal).
