I back off and never get it over 450 so yes 550 is pretty hot. And it's not going to go boom if you have a once off.. If you are constantly hitting 500 and keep it there, then overtime you can expect a short life from the motor - and turbo. It's gradual wear not a once off boom

Ive had mine to 580-600 up a long steep hill, if notice temps rising back off a bit and they drop real quick. Mine will sit on 350 at 120klms.

So an egt gauge is probably the most essential mod to stop it blowing. Hope it is cause it's the cheapest way to stop it going. I can't really afford to do all the mods ATM

Yep, EGT and Boost Gauge. Or the ECU talk from Peter, that monitors all temp I think, need to check with the Guys that already have it

my ecutalk on 2.8gu doesnt have egt or boost infomation,, but i think the 3.0l could have boost info on ecutalk im not sure tho but far as i know 3.0l has a boost sensor so im thinking ecutalk could read it...ask newkleer he's the maker of ecutalk

Nope ecutalk doesn't show boost or egt on 3l. But is very handy for correct revs, water temp, voltage and the alarms you can set it for. It does other things, but these are the main things I use it for.

You dont have to spend hundreds setting up an EGT gauge. I have a $60 ebay gauge, $2 steel nut from bunnings and $10 to weld the net to the exhaust pipe. Mine works great.

I agree I purchased the combined boost/egt gauge but the EGT part stopped working found that the Probe wire was broken, can get another one for $40 but 40 postage, go figure, its also too bright at night can't dim it.

I got a VDO egt gauge for 180 so will get the boost gauge and part with the digital.

While there is no definitive way in knowing the internal condition of the motor, by running the EGT and boost gauge, you can then see what EGTs and boost you are running. Prior to these gauges, your driving blind so to speak.

It would scare the bejesus out of you if you actually knew what boost you could be running when cruising which can also lead to extremely high egts. Some stories of 5-6psi at cruising & 550-600degC EGTs.

With a few additional simple mods minimum like clean/flush the intercooler, block the EGR, Install the Dawes & needle valve you can have a more reliable vehicle. And an EGT & boost gauge to see actual EGTs & boost pressure.

ECUTalk is an absolute godsend. It shows boost (as a percentage which is not very handy for my 2003 June series 3 ECU), Water temp, Volts and heaps of other stuff as well. Check out the ECUTalk website for more information. I am led to believe that ECUTalk can read the boost on the series III 04 patrols though.

I have a 2007 crd and recently fitted boost and EGT gauges my boost is 10-12 psi at 100ks cruising and EGT is 350 but will go sky high on a big hill 680-700 with foot flat and that is scary so am looking for ways to lower these temps but gauges are a must if you care about your viechle.
No i don't drive at those temps but handy to now how high they will get as i bought this ute 2nd hand 3 months ago .
