Look again, mine IS mounted behind the radiator... between the radiator and engine.

 

[Pile of parts]

Fan behind the radiator = between the radiator and motor. In front of would be between the grill and radiator.

For me it’s working great so far. It’s probably the widest fan out there so fitting it is hard. My passenger side head is about 1/2” from the firewall. If you have more gap than that it won’t fit. You’d really have to switch to a car accessory drive system. I cut the nipple off my water pump to clear with a bit of a gap.
You may want to stay away from that 4 wire fan. I’m guessing PWM is a headache you don’t want. Try the other one. Shoot, try the fan that came with the radiator. It might work for you.

Crap, that's wat I have in my cart.

This one moves more air but is obviously not suitable for our use.

Why is this one not suitable for our use? with a 3.6" depth this will be a good candidate.

Read the description. it is for low duty cycle use. not suitable for dirty or wet conditions because of the unsealed motor.

I found another fan out of a 2003 Lincoln LS V8 3.9L, end up buying both for $60.
Not sure if the Lincoln v8 fan will be better to run. It has 4 wires, power and ground, and 2 other small wires.

I got this fan installed and running, it's a 4 wires fan(pwm) but hand up only needing 3 of the wires. It's 18" with bigger blades and produces alot air, not sure what the cfm number is. Some googling says 3500cfm, drows 45amp when it kicks in.

Cools off the engine really nice. I have some opening on the sides of the fan but doesn't seem to lose air from there.

I am running it straight to battery and ground, and using the relay just to send power to the fan switch on wire once the ls pcm tell the relay to close.

Fan kicks in at 94 degree and off at 79.
