exchanger was sized for a bigger engine (bigger than my
'big' generator) but I intend to run only one genset at
a time anyway.

Thx, Al


Your present heat exchanger, while it might be big enought to handle a
larger engine, it's probably not big enought to effectivly cool two
engines.



What difference does it make if he's only running one at a time? Did you
even read the post you replied to?
