I put the plate back on my car last year after many years without but haven't got around to putting it back on since I fitted the re-cored radiator. Fair to say that it isn't vital for keeping my engine cool. I will put it back on the car and see if I notice any difference.
If you are using the same fans as I did please make sure that you fit a high output alternator ( around 95A) and wire it directly to the battery. Also rewire the fan override switch to operate the relay and not supply full current to the fans per original wiring. Make sure each fan has its own relay and fuse and that all wiring has a large enough cross section for the current it will carry.
I think the original fans drew about 7 amps each. The new fans draw 25 each!
It is also a good plan to have a controller that switches one fan on before the other, particularly to avoid the huge surge on start up. There are some really good PWM (Pulse width modulation) controllers that start the fans up slowly and speed them up as temperature increases, but check the reviews as reliability seems to be an issue. Also, before rushing to buy the same unit as I did you may want to read up a bit on the benefits of brushless vs brushed motors.
