Default LS3 water pump
I purchased a new water pump part number

89018052.


The water outlet on the new pump is on the passenger side while the original pump outlet is towards the driver side.

will this fit? It’s a 2010 corvette. I’m hoping it is not a pump for the LS2

I wouldn’t buy anything like this from Amazon or Ebay…to many counterfeit parts…also don’t use part numbers from the Forum or the Internet…get it from the dealerships parts department.

My buddies 2007 LS2 just lost a water pump and your new one looks like it will fit. Had my 2013 LS3 next to it as a reference, so you definitely have the wrong pump.

If the water pump are the same thickness it will work with new top hose.
but if it was me I go with the style you have,to keep the top hose away from the air bridge.
keeping the intake air charge cooler

In 2009 they changed water pumps because of the zr1 blower and pulley location.
