reverse rotation water pump ?

[dan66cj5]

Hi, Im new to the board..

I am looking for a reverse rotation water pump for the RWD buick 3.8 motors

Is there an application that uses this type of water pump ?

I am wanting to upgrade to serpentine belt system. My current plans require a reverse rotation water pump. I thought the Grand Nationals with the serpentine pully setup would have one ?? But my reasearching has not been able to find this.

Any help, thanks

what do you mean by reverse rotation, do you mean clockwise or counter clockwise?

if you need to know which way the water pump goes i can check see which way mine spins...

the motor spins clockwise.. so I'm looking for a pump that spins counter-clockwise. The pully on the waterpump would be smooth, and not grooved if using a serpentine belt. But some serpentine setups do have non reverse rotation waterpumps.. and i dont know how these setups work. Do you or anyone have a picture of a buick RWD v6 showing a serpentine pully setup ??

would you like me to take a picture of how my belt goes on? i think the water pump is smooth, cant remember off the top of my head.

Water pump pulley on the GN's/TR's is grooved...idler/power steering pulleys are smooth...

thanks for the picture..

Seems like the GN's didnt have reverse rotation water pumps with serpentine belt setup

What are all the circles for ? crank, water pump, alt, ps, ac, idler..ect ?
