	I have a question about the relative efficiency of Air
Conditioning and keeping the window open.  I am not interested in
gas mileage, but rather in maximizing engine power and not boiling
over.
	I have a 1981 Pontiac T-1000 (Chevette) with 1.6liter
4-cylinder engine and air conditioning.  When I normally drive, I
have the driver's side window open about 1-2 inches and the
econo-vent on.  I like to drive fairly fast (60-70mph) but often
do not get power for hills, etc.  Would I get more power with the
window closed and the AC on?  Would the engine be more likely to
boil over during a 1-hour drive?  (I wouldn't mind being able to do
75-80 with the AC going, but suspect I would need a better car for
that....)

P.S.	Keeping the window closed and the AC off is obviously not
an option.
