Tell me about it mate. That was the biggest issue I had with the old 40. I even fitted an engine oil cooler as well.
The radiator was made by Scott at A1 Radiators here in Chch. It was purpose built. Set me back near on a K. Tripple core. I had a hydraulic powered 'big ass' fan with custom shoud behind it too. Had to get it de-tune coz it was so freaking loud.
Think I got a video of just how loud it was.
Found it. (me being a cock)
http://youtu.be/dBlPiUyxaSgSkip it to around 1.20 seconds and you'll know what I mean.
I found that if the fan was mounted too close to the radiator it caused the air to cavitate.
I used to tow heavy stuff behind that 40 all the time and in the end after all the mods, it didn't over heat.
