yes, it goes "bad". All (I think) contain lubricating agents which
are important in the health of the pump. I would think every two
years should be adequate. I have no opinion about waterless, though
I suspect the "lubricating agent" still holds true. Ask the
manufacturer. Most have lots of information on the web...<br>

<div>I've searched the archives looking for any discussion
regarding how often to change the coolant in the BN7. If the
answer is there...I missed it. I'm running a 50/50 mix of
antifreeze and tap water and it tests o.k. as far as freeze
protection. This mix has been in the system for a number of
years. Does coolant "go bad" with age? Any thoughts about
the waterless coolant being sold on the market?<br>
