Metal dowl? If its a basic GM long pump, they come with a NPT pipe plug to block off the heater return if the vehicle is equipt with a radiator heater return. I've found the systems with a waterpump heater return are more effecient and heat the coolant faster than the style that use the radiator as the heater return.

Hmmm doesn't sound familiar...
Can you take a pic of it so we can see what your talking about? Generally most GM aftermarket or new pumps come with a Clamp, Pipe plug and gaskets. Occasionally they will supply you with the 4 studs and sealer. |
