So... I was just wondering if both the water pumps were the same... I did my swap and am using the CRV Water Pump without issues... So... is there a difference? The DIY says to use the EP3 pump.

I am going to say they are interchangable as long as the bolts all line up.

Something I have not actually checked is if all the different variants of Kseries use the same dia waterpump pully/wheel.

yeah.... thats what I was wondering to. When I called Honda for the new pump I bought I asked for the CRV one and they asked if it was Manual or automatic. It still works but I am just curious.

They are the same pump/gasket. I have personally interchanged each.

From personal experience the k24a2 pump is different to the k20a3.

Dunno about the k24a2 water pump, but any k with the oil cooler will have a different water pump and gasket than the k24a1/k20a3... so the coolant passage should be different as well.
