Overheating -- Corrective measure questions.

I just made the mistake of having the fan too far in the shroud. It really hurt my cooling. When I went 1/2 in 1/2 out it really made a difference.

I have concluded that the fan and the shroud must be matched. I had an old fan that was designed for the 1/2 shroud. Didn’t work with a full shroud.

I believe that if you have a fan designed for a full shroud, it would also help solve your problem. Most cars & trucks have the fan “all in” in the last 30 years. The fans are different shapes, but I am not smart enough to understand the difference.
