Water Pump To Timing Chain Cover Gasket

     

Water Pump To Timing Chain Cover Gasket  – There are three or four styles of this gasket and you will get any combination in a gasket set.  One gasket is so wrong that you wonder if it is actually for a water pump.  Another will work but is so odd shaped you wonder how it is installed correctly.  In the picture you see the water pump with the black gasket.  This gasket almost works but it will have you back removing the water pump and cleaning up a mess.  Yellow arrows show where this gasket will leak.  The water pump with the blue gasket is the  correct one.

 

To ensure a good seal, coat the gasket with Permatex Aviation FORM-A-GASKET Item 80019.
