Default Cooling System, fans and others

Hi,
I just got the radiator and thermostat replaced on my 1994 Camry (2.2
L4). It had a leaking radiator.
After that I noticed that still some white smoke (much lesser than
earlier) was coming out of the radiator from the right side. I showed
it to the mechanic once again. He said that it was probably some leaked
coolant dissipating in the air. However, I still see some white smoke
occaisionally from the same region. I have noticed that this usually
happens only when my air circulation control is set to 'Internal air
ciruclation' and the A/c is off. I have noticed that in this condition,
the fans don't simply start and stop intermittenly as they should.
However, not once does the car coolant temperature needle goes beyond
the half-way mark.
Also, the coolant level in the overflow tank does not seem to decrease
any radically.
I do not know if there is any problem in the car. But after spending
$450 for the radiator replacement, I would like to take utmost
precautions.
One of the doubts that I have is that, is it possible that one of the
plugs on the rediator may be loose, or that the pressure cap may be
loose shunted?

I'm assuming by your post that there has been more than a couple days
elapsed. If so, your mechanic is probably right as you would see the coolant
level dropping eash day if you had a leak. Sometimes coolant will accumulate
in small pockets and crevices and then splash out when stopping and etc. I
would suggest you keep an eye on the coolant level and temp gauge for a
short time. Also, in cool weather the fans sometimes won't kick on as they
aren't needed to keep engine cool, the coolant flow is enough. To verify you
need to monitor engine temp with a thermometer to see if fans kick on after
coolant temp reaches appx 200 deg. F.

Temp should not get above the normal half way range, fans in cool
weather may never run. Wait and check levels as days are needed to
evaporate spilled fluid. But keep an eye on the area you suspect it
could be a small leak or residue evaporating.
