While doing work on the cooling
system on my Yanmar
3qm30, (new exhaust
and manifold,) I thought I would do some maintenance
on my heat exchanger
. I wonder if anyone on this list has one of these, or knows where I might get instructions for disassembly.
Or should I just clean the outside, and put something caustic into the raw water
side of the fins, and rinse it out?
I know it needs a few new gaskets, a new thermostat, and a brass plug
on the end will need to be drilled out and replaced as it broke off.
Recommendations would be appreciated.
