Water Pump Bolts
Water pump bolts hold the pump to the front of the engine and clamp it against its gasket so coolant stays where it belongs. They live through constant heat cycles, vibration and coolant exposure, so worn, stretched or corroded bolts can lead to leaks. Many enthusiasts replace them when they swap a water pump, refresh an engine or tidy up a build with matching hardware.
This page sits in Engine Components › Water Pump Bolts. We currently have 1 product in stock here, from ARP: the ARP LS1 LS2 12pt Water Pump Bolts w/ Thermostat Housing Bolts Kit. As the name says, it pairs water pump bolts with thermostat housing bolts for LS1 and LS2 engines.
Confirm the kit matches your engine family before you order.
Check whether you also need thermostat housing hardware, since some kits include it.
Follow the bolt maker's instructions for thread prep, lubricant and torque.
Clean the mating surfaces and fit fresh gaskets while the pump is off.
To make sure you get the right part, pick your vehicle to see what fits.
