Have been thinking about moving my radiator fan to behind the rad for some time, but hadn't got around to it. The objective was to improve the cooling capacity and to provide better air flow through the radiator.
I removed the fan and spaced out the radiator with M6 spacers, then adjusted the coolant hoses a little. I then fixed the fan to the read of the radiator.
Not changed the rotation on the fan yet but may do later. Now the fan will sock air form the engine bay and forces it through the radiator. Ideally I want the fan to suck air through the radiator from outside.
Will see how effective the fan is and then may reverse the direction and compare results.
Now I have space for a large front mounted intercooler.
