Would to fit a shroud that carries the electric fan, just a simple bent box shape around the rad and with the fan bolted to it. Like this:  Mine will fold around the rad mount panel and bolt in using the bolts that support the rad, no welding involved. Unsure what thickness ally sheet would suit? Advice please! |

1,0 - 1,5 mm aluminium is fine. I made mine out of 1,5 mm. Just make sure that the fan cannot move and touch the cooling fins.

I've made a couple from 1-1.2mm ally on my projects. I have a selection of folders in my workshop making it easier, but clamping blocks of wood or steel angle/box either side and gently pushing or hammering will usually do a good enough job folding the edges over. Riveting on extra bits of angled aluminium as strengthening braces helps too

With a small rad like Andy's, a shroud covering the whole rad is fine. However, not so good on a wider rad, IMO. I started with a shroud covering the whole rad:  Very pleased with the result. However, after some thought and discussions with people who know a lot more about the subject than me, it was decided that this wasn't the best idea. This would be fine at slow speeds, but not at high velocities as air flow would be very restricted by it all having to pass through the fan. So we modified it to only shroud the fan, leaving the rad able to have free flowing air through it. Worth thinking about.  |

You could have cut some nice holes in it and cover them with rubber flaps.
Vw did this on the golf mk2.
As air gets pushed through the radiator when driving it will push the flaps open. When the fan kicks in while stationary it will suck the flaps closed so it needs to pull the air through the radiator.
