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
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.
