Fit perfectly - happy with purchase. Read more
Should be sold in pairs Read more
I bought a new ACDelco 251-743 water pump.It came with 2 of these bolts,you only need 2! If you find yourself needing 1 the following applies! This is nothing but a thermostat housing bolt. It is only worth this kind of money if you don't have access to a local hardware store! Do a little measuring, take one of the old bolts with you. Match the thread and save money,Buy a medium grade hardness replacement. Read more
