Can i get a mechanical injector pump for 4.2gq

It did this before new radiator or sock it did this stock standard thats why i changed everything one at a time .yes new waterpump

Yes I realize that but..
Is it a quality radiator or a $100 ebay jobbie?
Imo 4 core is killer overkill..
3 max.
But pretty sure stock is 2 and work fine..
Also what percentage coolent ratio are you running?

[landy96]

$500
50 / 50 nulon

$500
50 / 50 nulon

nulon ratio ok.
I know is said I'd bow out but
Ok a $500 radiator = partial info again.
Guessing it's a thicker dual or triple core job.
Maybe something that has probably been made for the colder european market, and thus not suited to our environment.

Or an overpriced falsely claimed, so called performance evilba rad.
Some sellers tell porkies to push below par product, That's the nicest way I can put it.

A thicker rad is not necessarily better.
Fin pitch has to be matched to the rad thickness for any performance gain.
Thicker with the wrong fin pitch can actually "BLOCK" air flow through the radiator.
In turn reduce cooling, so bad it could be worse than the standard rad, and ya over heat thinking "well it cant be the rad I just put a new one in".
I'm guessing your rad is not up to spec to suit your needs.
And hey I'm not preaching at ya mate, the one I just fitted," that was supplied to me", I think falls into this below par cooling scenario also.
Its a standard thickness core, but single core not dual core as std spec was.
But not any where as bad as yours is, thank christ.

4 core looks good 70 ml thick ..over heats with standard 2 core . only gets hot uphill slow speed.. not on highway towing trailer .

Was the viscous hub ever changed?

[landy96]

New viscus .with new waterpump .three new tested thermostats .

Is the fan on the right way round? Use a bit of paper to check air flow.

Have you ever cleaned the aircon core?, it also can block up reducing airflow through the rad core.

so you have a 4 core unit what brand? and type alloy?, and it over heats when going slow up hills.
to me it sounds like a combination of over fueling and reduced air flow.

Ahh what air filter set up do ya have, could it be restricting air, in turn also adding to rich mixture and heat stress.

[landy96]

Alloy radiator looks nice forgot what brand had red writing on angle on packet .
Yes fan in right direction .
Air condensor cleaned when radiator was out .
Standard nissan air filter .

All good points
But i have missed somthing ?
