Doing a head scratch on this one.<br>My son has a 98 Dakota w/3.9. Replaced the water pump a couple of months ago and found out the pump wasn't bad, just leaking at the bottom of the pump housing/block mating surface. It would appear to be doing the same thing again. It leaks only at an idle or just after shutting the engine off.<br>The surfaces were cleaned and a thin coating of rtv placed on both surfaces. I did notice that the gasket material was very thin as compared to other water pump gaskets.<br>It may be nothing more than a bad/poorly designed gasket. Has anyone experienced this problem before? If so, what did you do to correct it?<br><br>Bruce
