I think that is there only to relieve some flow pressure in the rad when the stat is shut. I think. Lol.

Only logical explanation I can see now mate is that a significant amount of coolant does go through that hole witnessed myself and not even under pressure.
All I can say is that the Jiggle Pin on the 88C I’ve just installed must be working as I roll down hills at 86C now instead of 56C before.
That surely has nothing to do with the differing opening temps of either?

For the greater good @mudski Old Mate!
Can you please drop in a $45 OEM 82C before our winters almost out now.

I’ll be keeping the TD27 88C in for as long as possible to see what may happen as we approach 30+ ambients again, flip flops awaiting in storage:-)

It will have to wait unfortunately Mark, as the Patrol is now a daily for the wife as her Mazda 6 is not going. Last thing I want to happen is make the Patrol out of action, I'd be really in the bad books then.
Max 30mins full bleed changeover after hours I nuffy promise mate!
Cringing myself thinking of such a beaut TD running 40C then back right up again, can’t be too good brother!!

Yeah I know. But, unfortunately priorities in life at the moment mean the Patrol see's no love. I have a Red ship box Mazda sitting in the garage i am supposed to fix, but feck knows what I'm even doing with that. Lol. I tried burning it but as we know, shit doesn't burn, so I failed there.Quote:

I’m truly shocked now, just back from a north west highway run and cracked the magic 600km for exactly 80L burnt. (13.3L/100km)
I don’t believe this old dinosaur family wagon ever did that even back when it was bog stock with only the factory alloy bar (2,500kg Tare).
Its now got a stupid amount of steel bolted on front/back/sides/top (3,000kg Tare).
Performance wise it honestly feels like its got say an extra 1/2 gear up those dreadful rises near Diggers Rest and Sunbury.
Full mixture today of 80/90/100/110kmph with engine temps 88/89/90/91C.
One more tank fill up and this new OEM TD27 88C thermostat has truly paid for its self folks[emoji106][emoji106]
EDIT: Todays peak ambient temperature pic below for my summer time reference safe storage :-)

Half burnt diesel stench has fully gone!
IMHO now these great donks need stabilised much higher temperatures than ever taught before, aim for stabilised 89.99999C averages maybe....?

Curious about your results I did some Googleing and I just found a study that compared engine coolant temp to engine performance.. i didn't read the whole thing but flicked to the results and looks like from 60 to 90deg generally speaking fuel usage drops but emissions go up...
Might explain some things. I absolutely wouldn't be surprised if Nissan ran it a bit colder to drop those emissions down a notch.
The study looks very specific but i think it would be a reliable indicator of what you could expect.
I'd be keen to try a hotter stat but i don't know if it would get through summer... I've always wondered about this. I figure technically your cooling system should still be able to maintain 88deg with the same efficiency as it does 76deg.. so really in regards to overheating issues the temp of the stat shouldn't actually matter?
