[C320-list] Bleeding calorifier for cooling?

[Michael McCretton]

Hi Graeme

I am not sure if this helps as I have a Westerbeke engine but I replaced 
my hoses a couple of years ago and had the same problem. The answer was 
to open a bleed valve which is postioned at the highest point of the 
engines hot water circuit for the calorifier.the. I have attached a 
photo which shows where it is on my engine. I recollect that you have a 
Yanmar engine. Hopefully they have something similar.

It was not very effective until I ran the engine and I had to open it 
very gently because of the pressure.

Regards

Michael
