Had a search through the archives but could find nothing on it so:
Do you just get it from a local dealer? (as the handbook says)
Or is there some other better stuff to use?
Mine has just dropped below the low level marker and I want to know what is best to add.

Thanks

 

If the coolant level has dropped at all I would suspect that something is amiss somewhere. Check all hoses etc. I have used Bluecol antifreeze, which is OK to mix with the stuff Subaru use in my old MY97 (hose had small split). As yet I haven't had to in the MY99.

 

Make sure that you use stuff that is OK with alloy engines
