Fluid type in heater system

[lunatic]

I am having my heater motor serviced today and the old heater fluid will be drained out and replaced. See image of my existing fluid.

I have heard that you need special glycol in the heater system, not just automotive glycol. Is that correct? What is suggested is Propylene Glycol (USP food grade).

Does anyone also know the fluid capacity in litres of the heater system?

Any advice would be appreciated.

Hallo,
I'm sorry that I cannot directly help you due to the fact that I'm driving the previous generation T1N from 2005.
Have you tried to contact Westfalia via email?

Hi Lunatic,

have a look here : https://www.butlertechnik.com/thread/hi ... 1K89w2NhPc
butlertechnik is for my opinion the best site to get any information about Eberspacher and Webasto.

I have general purpose antifreeze for 10 years without anytrouble.
