What temp does the secondary switch fire up at, and where is the switch for it located? This is a 91 HO Laredo with AC.

Next question, does anyone know what CFM the main and secondary fans are rated to flow (ballpark)
 
I think it turns on at 230* or somewhere around there.. It's controlled by your ECM or ECU or computer, whatever that thing is called... The temp sending unit sends the temp to the computer. Once it reaches that point, the the computer turns on the aux fan..

I don't know the aux fan CFM, but 2800cfm sticks in my head for some reason..

2800cfm is probably the total airflow for both fans combined.
The auxiliary electric fan turns on at about 220*F.
