    Re: water pump tool?

    No special tools. 1/2" socket wrench or breaker bar to loosen the belt tension, 13mm combination wrench for the pump pulley bolts, 10mm and 15mm sockets as well as a T45? Torx bit socket for the pump itself.

    Clean the timing cover surface very well, and use NO extra "goop" sealant. If you want to use some of the spray adhesive on the gasket to help hold things in place, that is fine. Also be careful of the finely threaded 10mm components. Don't reef on them, causing damage - spec is only 5 pounds.

    What he said. Permatex Ultra Copper spray is good stuff. Bright orange can, about 8 bucks. Coat both sides of the gasket, let it tack up for ~5min and install.
