heat exchanger ?

[cosander]

170 merc alpha 1. The endcap on my heat exchanger bent out I believe from freeze damage so I flatenned it with a rubber mallet and bolted it and the 2 rubber gaskets back on. Problem is I have a slight leak from it I am afraid to tighten it any more Is there something I am missing?

It is probly still slightly bent. Did you use new gaskets? Check the surface where it bolts to for an imperfection.

no reused same gaskets b\c they looked new.

Take the cap off and lay it on a flat smooth surface. Take a flashlight and go all around the edge, you will probably see a spot that is just a little high.<br />Tap on it until it sits flat on the surface plate, then try it again.

I ran into the same problem. It was much simpler for me to just buy a new end cap and gasket ~ $25. Leaks gone and I'm back to enjoying the boat with no issues.

Get new end caps, if one's leaking (there's not a lot of pressure in the heat exchanger) you might never get it right. Also, if you had a freeze up, check all internals and pressure test closed cooling system side.
