Thread: 80 series heater problem

Noticed that the heater isn't up to the job lately. Driving back from molesworth this week really brought it home, 2+ hours running and could still hold hands over vents and needed 4 layers on inside the truck.

Don't think it's thermostat or water pump, temp gauge is where it always has been, just under half. Radiator is full as well, could do with a flush though

Did a bit of googling and discovered it may be the heater core is gunked up. Anyone flushed one of these before?

Can someone post a pic of where (if it exist) the tap at the bottom of the radiator is for flushing. Or do I have to disconnect a hose and let it drain out.

Truck is a 1995 80 series landcruiser gx
