Meziere WP115S Water Pump Backing Plate Small Block Chrysler

The Meziere WP115S is a precision-engineered water pump backing plate designed specifically for small block Chrysler engines (up to 1990) and 3.9L V6 Chrysler applications. This backing plate is an essential component when converting from a traditional mechanical water pump to a Meziere electric water pump system.

Key Features:

• CNC-machined from billet aluminum construction for strength and corrosion resistance
• Black anodized finish for durability and show-quality appearance
• Fits traditional small block Mopar timing covers (non-Magnum style)
• Designed to work with Meziere WP114 series electric water pumps
• Seals the original water chamber in cast aluminum timing covers
• Includes necessary gaskets for proper installation

Many Meziere electric water pump designs cannot completely enclose the original water chamber found in small block Mopar timing covers. The WP115S backing plate solves this issue by providing a proper seal between the timing cover and electric water pump, ensuring a leak-free installation. This backing plate is essential for successfully completing your electric water pump conversion on traditional small block Chrysler engines.

Note: This backing plate is designed for traditional small block Mopar applications and will not fit late model cars with Magnum engines. For Magnum engine applications, use Meziere WP117 series backing plates.
