electric water pump

Post  cool40 on October 4th 2014, 12:35 am

I've been running a bosch pump on my car for a while now and its cooled great. I got it off a lightning heat exchanger and use the 3/4 hose to a Y block with 2 #8 hoses going to the block. the other day I ran up on an even smaller little pump from a Mercedes called an auxiliary water pump. I didn't expect it to pump enough being so small but it moves as much or more water than the other bigger pump. my car cools easy with the alky injection but I have no doubt this pump would cool a gas engine. its about the smallest pump I think you could possibly find so I thought i'd share.......

this is the pump....

Its surprising how well this thing moves water.I figured the dragster guys would like the room and weight savings. This particular pump looks a little pricey but a friend of mine has a few of these new for $100 shipped.

The housing is plastic but this pump being made as auxiliary water pump leads me to think it'll stand the conditions. I think its for several models from late 80's to mid 90's.I did a little research on them trying to find gph and such but couldn't find anything. I know bosch makes lots of different shapes and sizes.
