7137 no fan adjustments

[C.Roser]

i have a low thermostat ready to put on because its recommended and i want to do a efan swap. i have the latest software but there is no option to lower fan settings on my programmer what gives?

[mikel]

if it didnt come with an efan, you cant adjust it through the pcm...

[C.Roser]

there is a clutch fan and also a small fan on the right if looking into the engine. if that one or is it for the ac or something?

[mikel]

that may be for the AC, yes.

[C.Roser]

is it possible to gain that function post e fan swap?

on the ram trucks the small electriv fan to the right of the radiator is for the AC, , the actual cooling fan has a clutch--- you can put on an efan but it will have its own temp. control as mikel has said--- you do not have the option to change it since it did not come that way from the factory. Summitracing has some awsome options with control solenoids to adjust the fans or fan to when the are activated.
