Hello all, I have been seeing some staining under my heat exchanger dripping over the alternator etc.. I am hoping that it is simply the end gasket that needs replacement and not a crack in it. I have to look closer when I run up the RPMs at idle as I don't see any dripping when at idle. The hose clamp is tight and the hose looks fine. Is there an easy way to drain these prior to me removing the end caps? Do they have to be bleed out once I replace the end caps. This is the boats 9th season. 496 Mags Any other suggestions greatly appreciated!
