Hi Alan,
Thx for those SBs! My engine is circa 1990's, which explains the cap. I
would have expected the canadian rotax support/dealer to have included that
in my SB's needed to be done when I had enquired when I purchased Troy's
classic a few years ago now - I guess they missed it. I am running normal
glycol (not evans).
I am going to give the Triumph T2108005 a try. I am also going to purchase
some sort of pressure tester to ensure my system will have no leaks at 1.2.
Many thanks again!
