    (Seal placed on tube for shipping purposes)

    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).
