    Save your cash, just syphon a drop out and bung it in the freezer. :D

    Antifreeze also loses it's anticorrosive properties over time so should be changed every 3 or 4 years (my opinion). After a total drain (as much as possible) you should refill with a mix of 50% tap water and 50% neat antifreeze, distilled water is only used in batteries (or my Wifes :) steam iron)

    Tap water is fine if you live in a soft water area but definitely not if you live elsewhere!! I have always used distilled water for coolant top-ups/replacement with no problems. It is worth it to avoid adding another potential problem....

    I use Britta filtered water in my coffee machine, my kettle and my wifes iron and they do not suffer from lime scale at all.

    So the car gets Britta filtered water too. :D

    Hi, try this family of antifreezes from Comma:

    Link

    I've used the yellow, G05 stuff in my 300D and in the 300SL without trouble. The G05 is the same as Valvoline Zerex (if the peachparts US forums are to be believed) in the USA, which was what 1980's MB's were filled with from factory when they were exported there.

    There are data sheets with the MB approval spec number. Ensure it matches or exceeds that which is specified for your car. You don't mention what model you drive, but afaik, the G48 (green) stuff is widely used by MB owners, contains silicates and is good for 3 years.

    The red one is silicate free, and is the long-life variant - good for 5 years. I think members have used that or similar without trouble as well.

    I also use distilled water you can get from Robert Dyas to fill irons and the like. It's not worth the hassle of a potential water gallery furring-up and for me, it's a £2.99 insurance ticket against bad things happening to the engine.

    Oh, and the easiest way I heard of testing to see if there's coolant is the taste test - antifreeze has a bitter sweet saccharine additive / property. Obviously don't start guzzling from the expansion tank!

    thumbs up for COMMA GREEN antifreeze from me. Meets MB Specs.

    however, my brother has Adsa's own brand BLUE in his Corsa and hasnt had any problems.

    Please don't "test" your antifreeze like this. Despite the sweet taste it is highly toxic and can cause renal failure, cardiovascular failure, brain damage and death :eek:

    Pretty sure Dieselman thought Comma were OEM installed by MB, so the same stuff without the markup. :dk:

    If you live in a hard water area and are concerned about the water you put in your rad or iron - use the water from a de-humidifier.
