You might want to start a new thread asking that, someone might know how to bypass the pulse module for the fan.

The engine cooling fan is fused at 50 amps and I believe a full-on fan motor runs around 30 amps.
I'd say no.

Well ok... then I need a mod/bypass to make the fan run with the key on.

Fan runs with about 4 volts and goes higher with heat in radiator.

Iam here to tell you the fan wont last and will startle you if you direct connect it to the battery, it STUNNING at 12 volts, been there and done that.

Try it at your own risk, at 50 mph it is doing nothing anyway considering the forward motion. Enjoy Woody

Re: How to Always on Electric Coolant Pump SRT

Sometimes, with the AM radio on , when I first pull out of the driveway, after a first start , at around 1250 to 1300 rpm's, you can hear what is probably either the pump or the supercharger through the radio speakers. But yoou only hear it once.
