At Perri's German Auto Bahn we only use genuine Audi, VW coolant and distilled water.  The purpose of your radiator is to keep coolant flowing throughout your engine. If there is a blockage or a leak, your engine can quickly overheat and your vehicle will break down.

Coolant leaks are caused by cracked or deteriorated hoses or radiator failure. Radiators whether plastic or  metal are thin and easily damaged, but the number one cause of coolant leaks besides age deteriorated plastic radiators is corrosion due to contamination by tap water and incorrect coolant. We recommend only using the original coolant and distilled water. The Germans use several different coolants. Porsche uses it own. BMW and Mercedes have used the same coolant for many years which was the same coolant for 1975 to 1992 VWs and Audis which they called G11, (color blue). With VW and Audis dependence on plastic cooling system parts they came up with a long life coolant that has lots of engine sealer in it. It spec is G12 (color red). G 12 and G11 are not compatable there are not to be mixed together or with any other coolant. We had a customer who mixed Mazda red with VW red and all the plastic in her VWs cooling system got soft and failed. VW now has  a G13 spec (color lilac) which is compatible with G11 and G12.  The Germans are not alone GM has Dex Cool which does not play well with other coolants. Chrysler and Ford has at least two different specs. The Japanese also have their unique coolants. There are some quote unquote "universal" coolants out their but why take a chance. Because I work on the Asian and American cars of my German car customers, if you come to my shop you can see all the different manufactures coolant I have. You won't see that at most shops. Most carry universal recycled coolant. in 55 gallon drums. We looked into this and asked for the test(s) they ran to determine or get a letter from the vehicle manufacturers stating their coolant was compatible with the OEM coolant would not cause short term or long term problems.  When they couldn't I asked them if they would pay for any damage they said no.

 

Here is a classic example of why preventative  maintenance is important. This customer  had been putting off repairing his Mercedes leaking coolant pump, finally a coolant hose burst forcing him to bring it in. Fortunately it was in December and no damage to the head gaskets occurred.
