D series water neck

[preferredduck]

I use RTV High Temp and never ever hand one issue using it on this ...And I have done many to note

agreed with the high temp RTV, make sure it's high temp though not just regular, that stuff gets real hot. i think most of the time it's orange in color from most parts stores.

Thanx guys. I actually went with the "Thermostat and Water Pump" RTV before anyone answered. I'm letting it cure overnight so we will see how it does when I get home. If it leaks I'll try the red stuff.
