Your dealer's competency is questionable, wouldn't you first investigate the thermostat before pulling out the radiator?9

When I got a new radiator, it has highlighted in the installation notes, check for stray currents in the radiator, as otherwise the warranty is void.

Essentially, poor earthing could have current flowing in the coolant circuit, which could result in erosion in components from electrolysis and end up with possible holes in the core, etc.

Quick home check, start engine from cold, with radiator cap off and look for bubbling or coolant getting pushed out.

Last thought, are you losing coolant? The cap that came with my new radiator turned faulty after a few months and wasn't holding pressure. New cap and problem hasn't come back.
Don't let the b'strds get you down!!

Agreed

When it first started, he could drive for a few hours before it over heated, when opening the bonnet, the overflow bottle would be pressurised, and purging coolant through the small pinhole at the back (its a replacement bottle installed with the safari snorkel). Bubbles would also be coming into the overflow bottle from the radiator, and the coolant hoses from the engine were ROCK solid. once the car cooled down he could drive it for another few hours before it over heated again.

Radiator was replace, and he took it for 1 drive and the temps were all over the place, temps would rise to above 95 very quickly, then you could hear the coolant rushing through the engine (loud gurgling sound) and temps would go back down. He took it straight back to the dealer, which was when they said it was the thermostat.

Thermostat was replaced, and car was ok around town. Then he took it on a long drive for a camping trip last weekend, car overheated after 2 hours, then again after an hour. he left the car at camp all weekend, then on the drive home, it overheated 5 times.

Today he took the car to the dealer and it overheated on the trip to the dealer (15kms). Currently with the dealer being assess. We are hoping that they finally bite the bullet and just replace the engine.

If they come back with some BS reason again, go to the nearest mechanic, pay him to do a combustion test on the coolant and if it fails, write a report which you can then take back to the dealer.

Might cost you an hour of the mechanics time, but how much time & money could it potentially save, while getting the run around from the dealer if they are trying to push your mate past the warranty period.

Good news

My brother has been given the green light for a new engine under warranty.
Bad news, my triton is now sitting in his place at the dealer because a balancing belt chewed itself to pieces yesterday. Looks to be a human error on the servicing mechanics part (fingers crossed it has not damaged the engine)

My brother is picking up his triton with its new engine this afternoon, fingers crossed he has no further issues. He is tossing up selling the MN while he is ahead.

My triton is back on the road and running great also, all in time for the holidays. :D
