Water pump with a freeze plug

Well I'm not sure that's a good idea. Coolant being about 50% non-water, When it evaporates it leaves behind a green oily sludge which will soon plug the chamber, and then........over the top it comes, until it finally plugs that too,I suppose.
My water pump has not wept since I put it on in 2004. In fact no new pump I ever put on wept.
I think Gates is dazzling you/us with the fact that theirs weeps! I mean they even admitted it, right?
I will not ever be buying a Gates then.

Oh,Gee
I forgot I'm running a 7psi cap, and have since forever, so your results may vary,lol.
