Water Pump Leak

Make sure you clean the gasket surface with a razor blade. Apply RTV on the water pump and THEN attach the gasket to the water pump. Let it sit for a night and then smear some on the other side of the gasket and bolt it on.

I have put on and taken off my water pump 3 times and it keeps leaking. I have tried putting ultra gray on both sides and still leaks. Any suggestions.

-I have better luck with copper gasket spray adhesive along with a paper gasket, make sure the mating surfaces are clean; dry and smooth.
 
rtv and more tourqe. New pump? does it definately leak at teh gasket? when the bearings go theres a weep hole drilled through the housing to the shaft behind the bearings meant to leak if bearings are shot.
 
I've never had a problem using Permatex Ultra Blue 77B with a paper gasket. Make sure you use a new real gasket - not some paste/tube stuff that is supposed to replace or create a gasket - they rarely work on water pumps. Also make sure it isn't leaking from the o-ring and just running down making it look like it's from the gasket. The o-ring MUST be installed correctly or it will definately leak.
