I will tell you Darren that fan will be useless if you dont modify the clutch fan. I have the same fan, and have done some tests over the last month or so with my own Patrol. The new fan with a stock hub changed nothing. Adding a tube and a half of oil made slight changes, the hub was locking in slightly earlier, assisting is reducing temps quicker. I have recently added another 18ml, one bottle, and now the hub is locked totally. Temps today, being cold outside were lower again, the water temps actually dropped when the car was moving and rose when stationary. Which it never did before. The only issue now is the fan noise. Im not so sure i will be able to put up with it. But i want to see how it goes in real heat at 110ks, this is where my kettle would see 115c. I think i will remove about 10ml from the hub next to see the results.
This is from my own findings mate. I am sure results will vary from motor to motor.
