Can i get a mechanical injector pump for 4.2gq

[landy96]

Original motor stock standard was running hot and getting hotter up the range .. bang ..the replacement motor did the exact same thing stock standard thats why i changed every thing ...?
Second hand motor bought .claimed to have been recond done 25000ks sat for a time and looked yuk inside from old radiator water .that is what a radiator sock is for to stop any shale or crud blocking the radiator . Have always used them 40 years same as my father never had a broblem just clean and replace them when required .usually 12months with new fluid .

I go up the range very conservative light footed 60 ks max usually 40ks .this is not in the heat of the day. I travel up very early morning or at night .
I luv our gu its set up is right for us . we dont realy want to go back to a gq . I am even considering buying a donor gq for a replacement 4.2 motor with all the parts needed for a change over but i dont have the funds for that option either.i have not made up my mind at all .. im old school and i have always set up my 4x4s to handle hot weather easily

Apart from a passing remark from Robo i haven't seen the word thermostat mentioned.

What're the odds?

It has. Been replaced apparently.

Read this tread from the start, didn't realize or simply missed there was a 'separate thread" on the same subject.

These engines have been designed for std coupling fans, not thermo fans, so x3 on that, ditch em.
Yep for the hwy towing you do, std type arrangement should do the job .
Yes people run thermos but that's generally 4x4's slugging alone tracks etc with no wind speed coming through the front grill, on the black top that's not the case.
You can up grad the radiator, no probs, this will give you a larger level of cooling capacity, reserve more efficient etc not necessarily solve a problem.

Question ,do you have something like a bug screen on the front blocking air flow?.
Are you running additional spot lights? how many?
Do you have fitted the extra wide mud flaps on the back, these can contribute to poor air flow exit under a car, thus in turn reduces what can come into the front end.

And the sock it's restricting flow through the rad for sure.
Have you removed the thermostat also, wrong move there if so.
Dads car was probably running a fixed direct drive fan?, with max air flow, regardless of car speed, so this may explain the dif there.
so many possibilities given the list of potential causes here I agree get back to standard type setup.

comes off a little blunt, most certainly Not talking down, intentions are only to help ya mate.

Perhaps the other thread, can't see it here.

Even so there has been endless suggestions that a new thermostat be tested. Was it done?

Out of curiosity wtf is a rad sock?

1. A really cool Sock what all your hipster mates look at when you wear it and say, "Whoa, what a rad sock man"

2. A filter you put in the top radiator hose (usually) to catch shit before it blocks up your Radiator cores

3. A really shit idea that restricts coolant flow thru your cooling system

I tried it all standard and it got to hot at low speed under 40 kph going up range gets hotter faster at 60 kph thats why i went thermo fans for low speed hill climbing towing 8x5 trailer .it doesnt get hot on the highway towing trailer. It will be used for slow sloging towing trailer through tracks up north for holidays ..1 roofrack 1 light bar no mud flaps standard 32 inch tyres .
Tried three thermostats so far all tested and opened...that was first change from standard..then tried bigger radiator no change .. then went thermo fans still no change . Before going bush i fitted a very course high flow bug mesh . no change . I really do appreciate all the suggestions and help offered . Burping sounds good . Also curious about the suggestion of block the bypass for thermostat . Sorry for to many threads. Can anybody fix that.

[the evil twin]

AFAIK blocking the thermostat bypass is an old school thing for a different cooling circuit...
Doing it/trying it on a ZD30 might prove pretty spectacular.

I haven't seen it done but thats because cooling isn't nearly the issue with ZD30's that it is with TD42's
Maybe someone has done it and can post up...

[landy96]

Sorry whats an( afaik )
Like to hear about the blockoff ?anybody
