Originally I used a wooden rod as a dipstick but today I repurposed some ali bar into a more professional version.
Dead easy to do and easy to wipe dry between checking one side and the other. The wood soaked up the fluid so it was less easy to read.

Why there can't be expansion tanks with clear sides I don't know. But I now the tool for the job. The second photo shows the long length of bar on the outside so I could mark the halfway point.
