I know this has been asked hundreds of times but I can't seem to diagnose this overheating issue.
I've replaced the water pump, radiator, heater core tap, radiator cap, tried multiple thermostats, no thermostat.
I've bleed it multiple times with the factory requirements, it sits there for 2 hours idling, it sits at temp perfectly and does not move.
As soon as I take it for a drive and put it under load it shoots up in sections, it doesn't gradually move it jumps in 3 stages. Then as soon as your cruising at 100kmh it drops back down.
It's got me stuck, it doesn't seem to be overheating as such. No boiling or steam.
Any help would be appreciated.
