You are doing a great job of messing up potentially good thread with uninformed bullshit.

yes 350 is low. I want it to be low. As i said it is tuned to live for a long time. it aint no horse power hero. my old gq used to see 550+ day in day out but it went heaps harder and was a toy, not my work truck.

Please dont post in here again UNLESS you have tried cooling your turbo seperatly to your engine.
I dont wish to argue with you.



*goes out side to wind fuel screw in untill my pyro its 170 at idle*
glad my car will now become reliable
You've already received a lot of help and bitched about it. I can't see you being satisfied with the outcome of this thread.

Especially because your fuel screw has no impact on idle temps. :lol:

Mate, you can try some of those stick on temp strips as a guide.
Just bung them on the oil filter, sump, oil cooler, intake manifold or whereever.
They change colour at the max temp reached. Wont be real accurate though, but an indication at least

Dunno who this guy is but he has them for sale

I think places like Farnells and RS components flog them as well

Another thought.
Why not take the bonnet off and go for a spin?
This would ensure you are getting proper airflow around the engine and through the radiator.

I did this on my Patrol and temps were much better. Bunged on a bonnet scoop above the turbo and problem solved for me

Just throwing ideas at you mate.

I don't know what the water capacity of your engine would be but I will relate it to a GQ patrol TD42. With roughly 14 litres of coolant and a large radiator I doubt you would achieve a 20 degree increase of coolant temp from turbo coolant.

Also you cannot get super heated water from a turbo fitted to a diesel 4X4 engine, the exhaust temps needed would be ridiculous. How hot can water get at 13psi before it turns to steam?

The focus probably has a rad the size of your interior heater heat exchange unit but still a 20 degree increase in water temps still sounds like BS to me.

So to make this a real simple thing for you to work out on your own, disconnect the turbo coolant lines and go for a drive, if it doesn't heat up like it was with the coolant lines hooked up you have answered your own question. You could probably use a heat exchanger (small radiator) from a water to air inter-cooler (pwr or similar) to cool your turbo coolant.

I hope this was helpful and related enough to your initial question or the Mods can feel free to delete it.

I'm not an engineer so now I will FO.

Hi all...Im pretty sure the factory tubo diesel 79 series holds more water than the 1HZ 79 series.
PEACE...

Where does the water from the turbo return to? Not straight onto the engine temp sensor?
