L322 Water Heater Control Valve

Hello, I have a problem with my L322 and I can't figure it out.
I have no heat in the car and the first
thing I changed was the Water Heater Control Valve. Everything was fine for 2 days after which I had no heat again. I changed the valve a second time with a new one and the same story. When I
unscrewed the hoses I noticed that I had no coolant in the passenger HEATER core at all. Has anyone else experienced something like this? The valve is a Hepu brand.
Thanks

Your pretty much air locked in the heater core you need to get a hose on very gentle and flush it andvtry and connect it back up without losing to much coolant. Could also be a faulty secondary pump they do fail as well
