I have an overheating issue on long inclines, initially i thought it was the thermostat so that got changed and seemed to help but it still overheats the coolant (going by the needle) at a pretty fast pace. I can help the issue by lifting the accelerator until it levels out and starts dropping. The warning lights showed up when i first saw this was happening 'engine overheat'.. which was on a pretty steep part of the motorway.

Anyone had this happen?
