Water heater

[Jack19739]

I recently lost a bit of engine coolant on my 320, and now the water heater doen't work. I suspect an air lock in the hoses, but need specific advice on how, and in what order, to bleed the lines. Can you help?

First step is to

heat the engine up and open the bleed cock on the thermostat.Stu
