A machined back plate for newer Hemi covers, used in electric water pump conversions. It is a plate only, so it needs the matching Meziere pump to make a working setup.

Overview
A CNC profiled aluminum plate with a black anodized finish, the WP315S closes off the stock coolant passage in a Hemi timing cover. A molded gasket from the factory seals the cover, which completes the electric pump installation.
Many Meziere pump designs cannot fully enclose the cast aluminum covers found on newer Hemi engines, and this plate solves that gap. The limitation is that it does nothing on its own and is tied to one pump part number.
Who it's for
A Hemi swap or conversion where the timing cover chamber must be closed to fit the electric pump the maker names.
Pros and cons
- Closes the original water chamber
- Reuses the factory molded gasket
- CNC profiled aluminum
- Black anodized finish
- Not a pump by itself
- Tied to one pump part number
- Late model Hemi covers only
Performance notes
The plate has no moving parts. Its job is mechanical: the CNC profile mates to the cover and the factory gasket forms the seal, so coolant stays in the chamber while the electric pump does the flowing.
