| Interesting !!! ...
On circuits when racing, the unique cooling fluid approved is : Water !!!
but water and magnsesium aren't very good friends, espacially on Ducatis, coz the water pump is included into the alternator case.
Thus, if you want to keep your magnesium case as long as possible, you must empty the circuit frequently ....
However, if you use your bike on the open roads with a magnesium case, you can use special glycol water cooling without risk !!! Magnesium doesn't negatively react with this chimical fluid ...
Last advise :
- MOTUL recently created a special cooling fluid for the association Aluminium/Magnesium. The liquid color is red and issued from the range : "Factory line".
I already bought some bottles in order to test ...
I'm very confident after the study of the technical and chemical informations ...
Now, up to you !!! |
