Air cooling in very hot weather (desert)

[Howie]

Would it be possible to fit a fan behind the oil cooler? Or am I talking through my arse

This would help at idle and extreme low speed, the police version of the BMW RT does this.

I've thought of using a fan from a s4, but I'm not sure if I could get it in behind the oil cooler and I have no idea what the diameter of the fan is.

Listen guy ,, just keep it simple no fans or complications ... just change oil more frequently in very hot climates and use 15-50w
