My tdi b5.5 have a small coolant leak a month ago which meant i had to top up header tank twice. Anyway coolant isnno longerbleaking due to radweld.

Due to the forthcoming freezing nights i am a bit concerned of the antifreeze capabilities so bought one of those old school antifreeze testers from halfords with the green and white bit.

If u know what i am talking about then u will have used said item.

Anyway...i just tested with the engine cold but the measurement lies in the green sectiob which according to instructions is when the engine is hot...engine been off all day.

I am very confused! Anyone can help please? Ta very much!
