Mine is one of the ones waiting to get a new engine under warranty and has over heated 4 times now (3 while towing/1 unladen). On mine, the factory temperature guage needle doesn't move up until the coolant temp hits about 115c, so without a scan guage (or similar) or an anxilliary water temperature guage, you don't really have any warning that the engine is about to overheat or how hot the coolant temperature really is just by monitoring the factory guage. For example, my temperature guage stays in the same spot regardless of whether it is 86c to about 114c. IMHO I reckon there would be a few Tritons out there on the verge of over heating with their owners mindless to the fact of how hot the coolant temperature really is because the factory guage stays in the same spot.
Interesting this. I had the coolant recall done in 2016 and it didn't seem to be an issue, BUT
just this summer I was crawling up a hill out camping when I "smelled" burning and noticed the temperature gauge going up into the red line. I immediately stopped and shut it down, to discover the radiator boiling. Well, I started it back up as nothing was leaking anywhere and in no time it cooled back down again. Since then, whenever I tow up hills, it doesn't take long to get close to the red line again. Is this a sign of the cylinder head surface problem or simply how Mitsi automatics handle loads?
It isn't very good especially considering I had a brand new radiator installed just 2 months prior to the first overheat, because the original was beginning to leak [possibly from the extra pressure of the recall work?]. If regular overheating is going to continue whenever I tow my camper [not a big load mind you], then what can be done apart from extra cooling additions like thermo fan or AT cooler?
Might ring Mitsi and ask what they think about it. I cannot go about overheating every camping trip I make, especially when it is only just over 100km from home, ridiculous.
