stock dual fan amp draw and amp?

I just bought a set of stock camaro fans to replace my old clutch fan . Im not running a computer in my car and I want both fans to come on at once .Car is an 85 iroc with a GM creat 350 with headers , intake and carb

1. Can I run both fans on one 30 amp relay

2. How much ampage will both fans draw at one time .

3. What temp switch should I run on 185 off 170 or on 200 off 185

Re: stock dual fan amp draw and amp?

I went from a clutch fan to dual fans on my '83 and I have them on separate circuits with 30 amp relays.A single 30 amp relay will overheat with the load from 2 fans at startup.I used the factory dual fan wiring diagram as a guide.Also I have them controlled by external adjustable thermostats.They come on at 200*F and off at 185*F.
