LS3Whipple

Hi
need to mount a newer LS3 water pump, with the water hose on the left (driver side), belt is getting near the hose.

is it counter clockwise ? does the turn direction be looked infront of the engine?

Thx !

That is correct. It turns in the OPPOSITE direction of the crank, exactly as you depict.

OK, so I have to buy counter clockwise LS3 (newer version) water pump

I am always thinking of an electrical pump, because in low rpm the water flow through the radiator gets less and the tmp rises, fans must start on....
- electr. pump to help the mechanical pump
- electr. pump instead of mechanical pump, same lookalike and hoses, idler pulley to run the belt
- electr. pump instead of mechanical pump, seperate idler pulley, complete different pipes for cooling an heating passanger room

looks better now, but the new water pump has not a wide wheel to run the belt, hope it will fit.
