Hi guys, been out in the Orion these past few days, and noticed the hot air isn't blowing out HOT air...its just lukewarm...the blower itself works fine, and the temp adjusts as normal, but when its in the max hot position, it used to be way hotter than it is currently blowing...

Around 3months ago we did a full coolant change so I don't think there is an air lock in the system, as from memory, this has happened gradually

Another note, around a year ago, a brand new matrix was put in, again, blowing out piping hot air

Any pointers for me to check out this weekend?

Cheers!
