Their argument is that when the fan clutch is bolted it works at more than 100% the strength that the fan is supposed to work at and then provides a greater than normal/standard cooling effect.
They say that that is why when I have the fan clutch bolted it takes away my overheating problem but the problem is still there with their new fan clutch fitted.
They therefore argue that it is not the fan clutch that is the problem but some othe rpart of the cooling system. They suggetsed first changing the radiator and then the water pump (or both at the same time if I am feeling rich!).

The rationale sounds plausible, but that implies that the cooling system is on the edge of being adequate - to the extent that a partially blocked radiator will have it fail.
I am used to Mitsu designing with quite a bit of redundancy.
It would have been nice to try another Gen3's radiator, before you buy a new one.
(You and Marius should maybe get together with the two Gen3s and a 6-pack of cold ones!
