94218 Arrived at the shop for a coolant leak.

I traced the leak to the auxiliary coolant pump mounted under the floor on the right side of the cab.

There is an auxiliary coolant pump and a valve mounted on the right side of the frame.

The lines from pump and valve go to something in the van box. The coolant leak is coming from the small piece of hose that connects the pump and valve together.

I found coolant dripping from the pump connector.

The pump in question is a Johnson CM10P7-1.
