Is it possible when it has gotten hot at some stage, that any scale from within the block has loosened up, thus blocking up your radiator somewhat.
Just putting it out there as one of many possibilities.

IF IT'S NOT A NISSAN.
THEN IT'S A COMPROMISE
Tidy Whitey - 99 GU TD42Ti - Diesel Gas, (GUIV Turbo & Intercooler 8Lb boost), 33" Micky T's Baja MTZ's, Dual Batt's, Cargo Barrier, rear draws, HID Super Oscars, winch, Grinch & witch attached and more goodies to come
So this radiator should be ok then.
Humm ok try this,
when I recently did my injector pump upgrade, turbo and injectors the mechanic that fitted the pump and tuned it mentioned to me off the cuff about how he blocks off the thermostat bypass port and fitting a standard type thermostat instead.
and I quote him " Its to solve the td overheating issues ".
He taps the port and fits a plug in it to seal the port off permanently.
Maybe that can sort it. cheers.

New radiator had rad sock fitted at same time.
So i need details and photos on blocking of the thermo bypass does anybody in brisbane do this or can i do it myself
somebody said i can leave the solenoid disconected from injector pump
Do i just unplug the injector pump??

Pretty sure a rad sock is a radiator sock. It's used to restrict flow. Think it sits on the top tank. My brothers big block chev had one when he brought it. Don't really understand the purpose behind it.

Ok not to step on any toes here but imo there are 2 options..
You've either fitted a second hand motor that's close to pulling the pin already..
Or
You've over done everything so much it's now hindering itself..
And the very conservative 500 egt max probably isn't helping..
Again I think what was posted in the other thread is spot on..
You've made up your mind now fishing for the answer you wanna hear..
Imo strip off 2 of the 3 fans and fit the mechanical one back in..
Nissan only fit 1 fan and that's as a back up and to assist the ac condenser when on..
Keep the boost set to 18psi as yes they run better slightly higher (disregard my other post in the other thread as I thought for some reason you had a crd)
Get an aftermarket water temp gauge fitted as the factory ones are at best a rough guide..
80-90 degrees is quite normal.
100 is getting up there and should back off..
110 pull over..
Same with egt's
450-550 quite normal
600-650 back off
700 pull over..
If you've fitted a quality radiator, have boost set to a nice level (which you have), water pump and system is all in check then you shouldn't have an issue..
I guess one question I don't think has been asked is how are you tackling this hill??
It sounds big..
But are you sinking the boot to the floor in 5th or are you dropping back to 4th and cruzing up at less throttle?
You gotta remeber there only a small engine hauling near 3T and bigger tyres and roof racks etc only make it worse..

Pretty much agree with what they said ^^^^
Take out the Rad Sock and turf it as far as you can off the top of the range.
The 'factory' cooling set up, assuming no faulty components, on the ZD30's is good out of the box... thousands of them pull grey nomads and their vans all around the country so Thermo Fans etc aren't the answer IMHO.
The TD42 and ZD30 cooling systems are as different as chalk and cheese.
Don't go by any comparisons or fixes on one as they don't apply to the other

Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
