Booster, you have me stumped with that.
Marko, yet two more good questions, that I am unable to answer with any assurance of accuracy. However, I do not think that the system is plumbed into the coolant system. It seems to be a seperate closed loop.
The final question, is could this have been caused by a leak, rather than not having been filled correctly in the first place?
I know this. When the system works it is whisper quiet, which was the promise that lured me into this technology. The old propane system on the 2006 Roadtrek RS, was like having a 737 running in the coach
