Water Pump Bolt Kits for Engine Builds
A water pump bolt kit replaces the fasteners that secure the pump housing to the engine block. Even clamping force matters at this joint. The pump moves coolant under pressure, and a tired or mismatched bolt can let a seep develop over time. Many builders fit a complete kit during a rebuild, a pump swap or an engine bay refresh, so every fastener matches and torques the same way.
This section sits under Engine Components › Water Pump Bolt Kits and currently has 1 product in stock, from ARP. That product is the ARP LS1 LS2 SS 12pt Water Pump Bolts w/Thermostat Housing Bolts Kit. As the name says, it also includes bolts for the thermostat housing, so both parts can be fastened in the same job.
Confirm the kit is listed for your exact engine before ordering.
Check that the head style suits your tools and the space around the pump.
Note whether the kit covers related parts such as the thermostat housing.
Follow the manufacturer's thread prep and torque instructions when installing.
To see whether this kit suits your car or truck, pick your vehicle and we will show what fits.
