Bongo Fury

Mine has been refilled with orange colour coolant mixture. Halfords stock blue (standard) or red (advanced). Which is compatible with the orange version at present installed?

Bluecol-u is compatible with any coolant: but blue and orange mixed together isn't going to be pretty (although I'm not sure that bluecol-u is blue)

Can you not get some of the coolant is was filled with from whoever filled it? You can't go by colour unfortunately & if you do get the wrong mix, it could lead to allsorts of problems.
