Usually if looked after radiators will last 8 to 10 years. Might be time to upgrade.

Have a look at your clutch fan. These do not last forever and are well known to fail. Put some cardboard in front of the radiator turn on the air and use the hand throttle for a fast idle. Sit back and wait. You will here if the fan locks up as it will roar quite noticeably. If it doesn't replace it. Just be carefull that you don't cook it.

Think I just fixed my overheating issues on the 99' GU TD42T.
Seems to have been a fueling issue. Cleaned out the thimble in the injector pump, and fitted a lift pump and temps are now under control.
The injector pump will retard/advance if it has trouble getting fuel, this is what I think was causing me my grief.

what about the water pump, maybe your top and bottom hoses but you probably checked them when you replaced radiator eh?

New genuine Nissan viscous clutch fan hub

Yep, make sure its a genuine Nissan one.
I stuffed around with 3 aftermarket ones that didnt work properly, before putting a genuine one in with no drama.
