My son just called, his 2005 Cummins is leaking coolant somewhere out the front of the engine, dripping on the steering shock on the pass. side. I believe it is the water pump, but I replaced it just a year ago with a NAPA unit. I will have to see it, but where is the thermostat located and what type of gasket does it have? Also, what other antifreeze leak could come from the front pass. side of the engine? We put on the water pump, all new radiator hoses about a year ago.

Did you check the overflow hose and connections? The thermostat has a seal built into it, I believe. (My 04.5 did anyway. I have seen water pumps dump within a year. A small mirror will help you look under the pump to see the source of the leak.

It's very likely the rubber hose on the passengers side of the block. Look under the exhaust manifold close to the back of the block. You'll see a short piece of rubber hose that connects 2 metal pipes together. It's got 2 worm screw clamps on it.

You can either try tightening those clamps or, you may have to replace the piece of hose. It's a 7/8" hose and needs to be high temp. You'll need a 3" piece. It's tricky to get replaced but, can be done in your driveway.

Don't be surprised if its the water pump. They stink on these things. When mine went out it was pouring on the steering stabilizer also. I would check what everyone has stated above first though.

Seen quite a few posts on here about the napa water pumps not lasting very long at all.

Mine was recently dripping on the shock and I followed the leak up to the weep hole at the pump. replaced it with a Bosch from Pep Boys.
