Sleveritt, I am sorry, but I think you have gone in the wrong direction with this.

The amount of engine cooling you need is directly related to the amount of power the engine is producing.
The fans are there to help the increase air flow through the radiator when you are travelling slowly, or stopped in traffic. At these times, the engine is not working hard, but the radiator still needs air flow. What you have done will possible help in this instance.

But by far the greatest amount of cooling is needed when you are travelling at highway speeds, uphills etc, when you have the gas pedal to the floor.
At these times the fans do little, or no work at all.
The air flow through the entire radiator frontal surface caused by your forward motion is enough to cool the engine.
The cover plate you have installed will reduce this air flow by around 50% by the look of your installation.

Bottom line is that I think you will overheat on extended highway driving.

I hope I am wrong for your sake, but have a plan B for getting home the first time you go for a long drive.

Regards

Did you notice which way to radiator tubes are facing??? I said the front "pushers" weren't working, so I removed one (and only one, leaving the A/C condensor fan), and started working on these (for the rear).

The metal is a shroud from the rear with the fans there. Basic geometry for circles and rectangles proves that without a shroud, you are giving up over half the working surface area of the radiator.

Nice try though!

Okay, think what you like.

I hope it works for you.

Are the dual electric fans still running the full side shrouds? I think what PK is getting at is how can the air trapped by the shroud you made get out. I am sure that the answer is through the fan holes, but if the sides of the fans mount to the rad surface doesn't that in effect create a seal that would hinder air from moving from the aluminum shround area to the holes for the fan? If you plan on mounting the fans to the aluminum shroud instead of the radiator I can see this working, but I'm not sure if you leave the fans mounted to the radiator.
