Anyhow all I can say it keep pushing them to get it sorted I have been driving my time mob for over a year waiting for the next service with the coolant dropping and me topping it up until the next service to get it pressure tested again, (first one was fine) and the failed the last 3 should have the new motor in and installed by next Friday if all goes well. Goes to show that there are still issue out there and to just be persistent! Thanks for all the info has helped me when talking to the dealer so they know I know what is going on and what I’m talking about!!! Winning ! Oh and car just hit 60000kms

I am new to the triton world. Bough a MN 2011 4 months ago with all the fruit on it. Full service history and no issue when checked by my mechanic pre purchase. It was OUT OF WARRANTY and I never heard of this issue.
Last week on the way to a camping trip with the family, 1 hr down the highway the engine light came on and temperature gauge went to red.
Limped into the ultratune shop in Goulbourn. The mechanic that locked at the car said he had worked as the mechanic at the local Mitsubishi service centre for the previous 5 years.
He advised me of the know issues with overheating and machining problem with the block. Took him all of 3 seconds to confirm my MN was another casualty and to take it to the Mitsubishi dealer down the road to see what could be done.
He confirmed he was dropping in 3 engines a day at one stage due to the issue.
Yesterday, Mitsubishi called gving me out of warranty thus out of my pocket speech. After some quick talk I convinced the foreman mechanic to put in a good will claim to MMA whcih he was good enough to do.
He said he had to take the head off regardless to assess the damage and potential cost. I reluctantly greed as my repair options have been reduce.
Hoping these guys give me a fair go. Looking at ths tread I am wondering why on this good earth I bought this car outside of warranty, shame as the MN is really decked out to go anywhere less this problem.
Hope this can be overcome. Will let you know what happen. Appriciate any advice.

They kept it a few extra days and said they were going to remove radiator and send for testing.

Car did not overheat, BUT when i got home i let engine cool right down i noticed that the coolant had risen inside the coolant reservoir considerably above the upper level mark. As I unscrewed the radiator cap there was considerable amount of air/gas bubbling back through the reservoir. On inspection there was no coolant under the radiator cap. I'm thinking that over time as more coolant is expelled or evaporates it will overheat again. It does not seem to pull the reservoir coolant back into the radiator. What does anybody else think?

Update as I thought my thoughts were confirmed last Sunday 28/1/18 towing Caravan back to home, 200 km trip, 130 km in the car overheats and goes into limp mode, air conditioning fails. So back to Dealer again this week and at least this time given a loan car. Will update when I learn of outcome.

RESULT!!!! Update 9/2/18 Picked up my Car local dealer brand new engine installed within a week! Service Manager showed me old motor could clearly see the tooling issue with pitting around the cylinder block allowing gas to escape and enter the water jacket. However he could not guarantee me it will not happen again. He told me that 1 in 4 of the engine assembly lines had the tooling issue. So 1 in 4 engines have this issue but they do not know which ones they are! Strange I thought they would have all been coded. So they knew of this issue as far back as 2013 I think and continued to install the defective engines, my MN was manufactured MAR 15. I cannot understand if they knew of this problem why did they not remove the heads off the engines and inspect them for the pitting before installing them? My guess is it was all about $ and some of these engines may not fail if they are not under load, mine only did it towing a light caravan.

Has the water pump been replaced as part of the rebuild?
Have you considered a slightly lower temp high flow thermostat?
My piece of foil (the thin radiator) in my ml, sprung a few leaks a few months ago. I decided to replace it with a double thickness unit (28 v 16mm) and it provides much better capacity to keep temps under control, esp as I run an electric fan.
