Hot air from below engine?

Hmmm....

Not the heat exchangers and cannot seem to find any particular isolated area so am starting to think it's not a good sign... unless of course they all blow hot air (as in loads) immediately underneath engine on left side more than other side?

any idea what it could be?

It's called a great big fan that cools your engine. The hot air has to go somewhere and out the rear end is where it goes. Great on a frosty morning to keep your legs warm. It's normal.

thanks... hmmm took me 16 years with same bus as daily driver to find that out!! Been so used to getting air from h/exchangers annually to notice what it should be like.
phew!

cheers!
