Amp rating for cooling fans

I am starting to set up my radiator and electric fans
for my 5.3 connect and cruise package.

The instruction package says the fan for cooling should be
hooked up directly to the harness supplied. The fan is controlled
by the ECM at 207 degrees, and the power is already fused and relayed.

The question is, how many amps would this fan circuit be rated for?

Thanks

Re: Amp rating for cooling fans

To many variables are involved for anyone to give a definitive answer.

My guess is 25-30 amp momentary, 15-20 amp constant.
