Hi Everyone,
I recently ran into a problem with my 1980
Westerbeke 30 hp
diesel engine. I neglectfully did not replace my zinc in a while, and unfortunately the zinc corroded and broke off inside the
heat exchanger. In addition, I have a bit of a
coolant leak coming from the end cap of my
heat exchanger. It's pretty bad, it's leaking even when the
engine is not on.
So, I am seeking some
advice from those that are more skilled than me with engines. To fix both problems I will have to take the
exhaust manifold, heat exchanger, and mixing
elbow off completely.
Does anyone have any tips? Beyond the obvious of removing the manifold bolts, changing the
gasket, etc. Here are the things that I've thought of:
1) Use penetrating
oil on the manifold bolts a few days and a few times in advance
2) Take the heat exchanger to a radiator shop to pressure test
3) Bleed the
cooling system before running
4) Take before pictures of everything assembled
5) Label hoses
The full
project steps I've written out here. Feel free to destroy it:
