Rad fans
I just LS1 swapped my 96 3.8
The low cooling fan doesnt come on when the car is on. Does the engine have to be up to temp before the low speed fan kicks on?

From the GM Service Manual for 2001 Camaro:
For the LS1:
"The PCM commands low speed fans on under the following conditions:
-Engine coolant temperature exceeds approximately 108°C (226°F).
-When A/C is requested and the ambient temperature is greater than 10°C (50°F).
-A/C refrigerant pressure exceeds 1482 KPa (215 psi).
-After the vehicle is shut off if the engine coolant temperature at key-off is greater than 140°C (284°F) and system voltage is more than 12 volts. The fans will stay on for approximately 3 minutes"
"The PCM commands High Speed Fans on under the following conditions:
-Engine coolant temperature reaches 112°C (234°F).
-A/C refrigerant pressure exceeds 1710 KPa (248 psi).
-When certain DTCs set."
Hope this helps.

So if its over 90 degress outside and I have the A/C on my cooling fans will come on ?
