Waterpump kit tips

Indeed! The original pump has the impeller exposed when not installed. That new pump looks like it has a solid back on it, making it the type that is not mated to the block but is free-standing.

I would have to doubt that they are interchangeable. For some reason, very few engineers actually design their stuff to use existing parts that are proven to work well. They design brand new items and don't give a thought to making things work for multiple applications.
