Yo Unregistered: Join us for the April 5 meeting when it will be Recovery night. We will have demonstrations working with winching, recovery and spotting. We will meet at 7:30 p.m., or a little before at Jefferson County Fairgrounds (not Stevinson Toyota but nearby).
I don't think a shroud would do much with the fan resting flush against the rad. I looked and there might be 6" between the rad and the motor.
You're right, a shroud won't do jack unless the fan is spaced back enough from the rear of the rad to get flow through alll parts of the rad. But with 6" it sounds like you have plenty of room to mount the fan farther back and use a shroud.
