    I have a 330 water pump that needs to be rebuilt. Anyone know of a good rebuilder in California or anywhere else in the US? Thanks.

    The 330GT does not have a waterpump that you can remove and rebuild separtely from the engine. It is integrated into the front timing case of the motor. There is a waterpump seal, seal ride, an oil seal and seal tube that all can be replaced on the engine.

    Do you have a 4 head light car with the belt driven water pump with the electro clutch for the radiator cooling fan ?

    Which picture is your car?

    Both are fairly straight forward jobs. I've done many.

    The first type is a separate part and can be removed for rebuilding.

    The second style is driven by the timing chain and frequently is done "in the car".

    You need a few special tools to get it right.

    Prancing Horse #140 - TechNotes has a good description of water pump rebuild on a Daytona, but the principles are the same for other V-12s of the late 60s and early 70s. Unless the impeller itself is shot, this is not that tough, as kits are available.
