Reverse Rotation Verses Standard Rotation Water Pump??

Hi...what is the significance of a reverse rotation water pump verses a standard rotation water pump serpentine set up? Does anyone know??

all factory pure serp setups used a reverse rotation pump

you can tell by the back(flat, smooth) side of the belt drives the water pump pulley

in theory, the pump is cast slightly differently and has a reverse impeller in it, also, the reverse rotation pump has a slightly smaller bolt pattern for the pulley

the theoretical benefit is that by allowing the coolant to flow to the heads before the remainder of the block, u can remove more heat from the combustion chamber

a cooler combustion chamber because u can run higher compression using the same gas

higher compression means more horsepower

It depends how the belt is routed as to what pump ya use.Ya also have pumps for marine reverse rotation engines that are used in a dual engine boat to cancel the prop torque.

Thanks for all your answers!! I was just wondering the significance behind the reversible one...that is the one I am using currently on my setup. Very informative!! Thx again!!!

he asked about reverse rotation, not reverse flow

he asked about reverse rotation, not reverse flow

haha, whoops

haha, whoops
lol, happens to me too
