Default Re: Water Pump Flow Rate

While im at it, Water "Pumps' in Cars are impeller pumps so they scoop and push the fluid similar to running around a kiddy pool to make a vortex.

A lot of people mistake impeller pumps with other types and expect big things from them but what you get is long life, minimal moving parts and the cooling job done.

they usually die after time and commonly #### the bearing and shaft seal leaking coolant but on cars left a while and without coolant can suffer from the impeller vanes (that move the water) actually rusting away.

So its all good from the outside, but rusted away on the inside.
