Stock 2000 LS 2.2 auto. Central Florida.180 thermostat, purple ice (don't scold me please) in fresh 50/50 coolant. Imperial probe type controller set to come on at 195. Condenser and radiator are about 2 years old and clean on the outside with no damaged fins.
The fan struggles to keep the engine cool in the FL heat with the AC on.
Hitting an indicated 235 degrees when moving slow which makes me uncomfortable.
I'm going to try a 16" fan that is "3000 CFM @ 15 amps". (Yeah, right).
My question is, should I mount it against the radiator like the cavalier fan is or should I mount it to the "end" of the stock radiator shroud where the original fan was?
Opinions/experience is appreciated.

Well, you should be running a stock thermostat, a 180 is not going to help you. Fan shouldn't come on until around 210 or so unless the AC is on of course.

I have a Tempo fan and fan switch and I have no cooling problems over 100 degrees outside and 80-90% humidity at times.

Here in Florida the AC is always on.

Is you fan against the radiator or in the shroud?

I changed out the stat a few days ago, makes no difference. I plan to put the 195 back in when I install the 16" fan.

It's in the shroud, it's the factory setup from a early 90s Ford Tempo.

Best pic I have of it:

I always use Intrepid fans and they just plain work. I am in Las Vegas where temps see 118°-120° and road surface temps of 130°-150°
