Another Rad/cap/boiling issue...

plus 1
make sure that all the air is out of system by loosing the air bleed screw by the thermostat.
let it puke out what it don't need then leave it like that.

Thanks - yes did that one when I replaced the RAD.

While this is true, I would not recommend it if you park your Rocket in an unheated area where temps get very cold (like where I live)... 30/70 protects you down to 8.6F and 50/50 down to -35F. Since I live in an area that often gets down to -40F in winter, I have my antifreeze water mix slightly higher than 50/50 checked with a hydrometer. In this instance, more is better. If you live in the south, who cares.... ride

I'm in the UK and she sits in a heated garage when not in use so less of a risk where I am
