Quote: Water Wetter... or you can use water soluble oil but you need some lube in there for the pump instead of straight water
I have always wondered about water pump lube? What does it lubricate? Isn't the bearing sealed?
I thought the same thing... but when I built 1 of my engines with a electric pump I didnt have anything but water in it... first day at the track the pump seized ... was told to run the WW for lube... put it in and turned the pump with a allen wrench to break it free and havent had a problem since
