Thats a sweet looking engine compartment! Wish mine was filled with that!

Yeah, I've learned that you can turn off the fans so your fans don't splatter mud all over inside your engine compartment but that doesn't mean the crank pulley won't take over the fan's responsibility. /forums/images/graemlins/rotfl.gif

You think those two fans will pull enough air? I have a 7 blade mech fan and I was going to add some electrics to that for the trail but do you really think that's enough?
Well, I can say that the temp stays at about 210 in town so I think it's okay. Seems on the highway the air is deadended a little and it gets warmer. Also there is a pinhole like I said so really hard to say what is going on for sure. I have recently acquired another rad so we will see if that fixes it. They really move quite a bit of air though. I would have to say more than the factory fan did. I still haven't gotten a thermostatic switch to operate them. So far they are hooked up to a toggle. That will soon change.

thats a bad ass set up, what are the fans from or are they after market? /forums/images/graemlins/k5.gifto /forums/images/graemlins/truck.gif

You need to "skeletonize" that shroud, and make sure your fans are off when moving. You are blocking airflow over what looks like half that radiator, and that is EXTREMELY important when the vehicle is moving over about 25MPH.

IIRC I saw some rubber flaps on a VW(?) covering holes in the shroud. At highway speed the air blows through the radiator and shroud flaps. When the fan kicks on the suction keeps the flaps closed and draws air through the radiator. /forums/images/graemlins/thumb.gif
Also I hope you're using a relay with that fan. In my youth I bypassed a broken temp switch on a Saab 99. It worked great for a while.... then smoke rolled out from under the dash as all the insulation from the wire melted off /forums/images/graemlins/blush.gif

I was trying to figure out just how to cut holes in the shroud without getting the fans sucking air from the wrong place. Actually the whole radiator is covered by the shroud. I might just try the rubber flap idea if the bigger rad doesn't clear things up. Ya, I have a seperate relay on each fan. Thanks for the idea.

Looks good, Kert. Love aluminum diamong plate.

As long as those fans are mounted as close to the radiator as possible, that isn't an issue. Those fans already have an integral "shroud", anything outside of that isn't helping matters. If your fans lacked that outer "piece" that contains the blades, you'd need an additional shroud to keep air flowing through the radiator. With a shroud, you just need the fans against the radiator to make sure all the air they are pulling is from in front of the radiator, not behind it.
No reason to run the radiator surface area restricted unless its so cold out the coolant won't come up to temp.
