A couple of things:
I moved my bus out of the barn last Sunday to sweep it out and circulate some fresh air. When I pulled it in and disconnected the chassis, I smelled antifreeze. After checking, I found a leak exactly where Dale’s picture shows—mine is dripping too. It was on my to-do list, but now it’s an immediate issue.
Secondly, Prevost has had a fix available for this issue for several years. While searching their website for recalls and technical bulletins for my coach, I found one titled “Improved Surge Tank Hoses.” It’s listed as a non-reimbursable repair and is dated November 1999.
