Thanks for the help! I've ordered the plugs.
Speaking of which, there is a hole under the bolt holes, on the passenger side of where I mount the water pump. I see on my pump it allows coolant to flow thru to the radiator. A pipe plug that fits the hole came with the pump. Hmmm... no instructions on whether or not to use it. Both of the gaskets for the pump have a third hole. Do I use that plug? Can't imagine why I would.
