Water Pump Back Plate for Engine Cooling System SKU: QT37556123

When your water pump housing develops cracks, corrosion damage, or bearing bore wear, the back plate often suffers similar deterioration that compromises the entire assembly. This replacement back plate provides the structural support and sealing surface needed to complete a proper water pump rebuild.

Key Benefits

• Precision-machined surface ensures proper seal between pump components
• Heavy-duty construction withstands cooling system pressure and temperature cycles
• Exact-fit design eliminates alignment issues during reassembly
• Quality casting resists corrosion and thermal stress over time

A cracked or warped back plate will cause persistent coolant leaks no matter how good your other pump components are. Whether you're rebuilding your entire pump or just replacing worn backing components, this plate gives you the solid foundation needed for leak-free operation.
