Title: Water Pump Gasket
Post by: Dan Cluley on July 29, 2009, 02:01:53 PM
I'm replacing the pump on the Chrysler (383 if it matters) and the new pump comes with a thin fiber gasket.   Does that go on dry, or does it need some sort of sealer.  If so, what kind, and one side or both?
 
I probably should have wondered about this before taking everything apart, no? (http://www.moparfins.com/forum/smileys/smiley36.gif)

Permatex Hi-Temp RTV Silicone Gasket Sealant #22073.
 
Apply a bead to the housing.

If the surfaces are clean and pit free, the gasket by itself is fine.  But a very thing layer of silicone will be an insyrance policy.  So thin you can almost see through it is plenty.  Let it set up for 10 minutes before putting the gasket on.  A mistake many people do.

I spray it with Permatex High Tack on both sides.
 Rolls Royce uses Hylomar gasket dressing...which works well and  allows it to come apart someday.

I have a whole bunch of those gaskets...never used 'em...a little silicone bolt it up and let it set up for a half hour or so then fill it up and get going!!

The local hardware had Permatex#2, so that's what I used.  2 days, and almost 100 miles and no leaks.  (http://www.moparfins.com/forum/smileys/smiley4.gif)
