Hi all. I have a 100 series (2004) with 150,000 on the clock, I overheated it a fair while ago after snapping belts (reason unknown. since then the car over heats when under load though it is fine in winter up here. There doesn't appear to be any oil in water or vice versa. I have changed out the radiator, water pump, thermostat and viscous hub, A mate who is a mechanic has also done the head gasket and nothing has changed. My question is: has anyone had similar problems, does anyone have any suggestions? Thanks in advance Cheers Jamie
