Truck Water Pump Steam vent question? Is there a good place to take the older truck water pumps for the steam vent? Almost all of the pictures I see with the pump tapped, don't match the pump on my 2002 5.3L. It doesn't have the flat spot on the top, or the nice spot on the output ???? There is a nice flat spot on the front of the pump though, will that work?

Most of the how-to articles are for the Fbody pump with a front outlet. Trucks are top outlet
Tapping the front will work, but be careful the aluminum is very thin and easy to strip. You also have to retap the hole each time the pump is replaced over the lifetime of the vehicle. Its much easier to Tee the steam line into another part of the cooling system, such as a heater core line or a port on the radiator

I picked up a hose splice on eBay with a provision for a barbed fitting, I'm going to put my steam vent in the lower radiator hose. The splice came in a blue color (for the ricer crowd I suppose) but I'm going to blast it and spray it low gloss black so it "blends in" with my hose.
I'm using a 2004 vortec engine and throttle body with a LS1 intake and there really isn't a room to tap a steam vent anyways.
