I am in search of the part number or O-ring size of a cooling component. It is the outlet pipe for the water pump and it also connects to the lower radiator hose. There is a metal pipe going into this fitting that requires a rather thick O-ring that I can not seem to find. Any help on the name of either the metal tube earlier referred to as outlet pipe or the o-ring size would be great. Thank you!

 

Go to your local Mazda dealership's Parts Department and ask for this part number.......

E30115287

Or, give them your truck's VIN number and ask for the Water Pump's Coolant Pipe O-ring.

They should have plenty of them, as Mazda used the same O-ring for a bunch of their vehicles.....and are probably still using it! It should only cost $2.00 to $3.00
