Noticed that my 2006 1.4 petrol focus is about 1.5cm down on coolant
it's pinky in the container, having never gone near coolant in a car (old polo never needed the stuff, always stayed the same) I'm not sure where to get it and whether to fill it to the max level or slightly lower etc.
In work we have blue universal coolant for the boats (diesel engines) I've a feeling its all the same but could be wrong, I have no intention of using the work stuff (which there'd be no issue with) in the car. Does the colour make a difference?
all advice appreciated
