Frage Boiler expansion tank

Hello from England,

We have a Columbus 601d for one year now and love it.

I recently checked the boiler expansion tank, which is now looking low. The handbook says to top-up with any vehicle style anti-freeze.

Does anyone use a particular formula?

Many thanks, Stuart.

Hi, Stuart.

Welcome in this Forum.

I also have a Columbus 601 D. My Westfalia Whisperer (workshop) recommended me 50/50 (water/cooler antifreeze). I do it like this. Works perfectly.

Greetings

Frank
