My 06 duramax has been making a noise around the thermostat housing.I took a pair of stethescopes and narrowed it down to the water pump area.I unhooked the belt to check the water pump and still mkes the noise.Then later i am told it has a gear driven pump and the noise is gear slack and is normal.Is this true and has anyone else had this problem?

called around to check prices,the pump can be purchased in 2 pieces a gear and the pump housing.The gear is driven directly off the end of the cam to pump if ther is ever belt failure so it will continue to cool the engine.
