Citroen saxo coolant

[Jonathancilia]

Hi, i need to change the coolant of my citroen saxo 1.5 diesel, what is the colour that is supposed to be in the cooling system, red coolant or blue ?

These engines will use blue Ethelene Glycol as standard but do check that OAT has not been used in the past... This is likely to be orange. If so then use OAT again as blue Ethelene Glycol and OAT do not mix. If they do mix, bad things may happen as it tends to make the mixture coagulate (clot).

If OAT has been used and you wish to revert to blue then a very thorough flush will be required..

Not that some long-life Ethelene Glycol may be red or green in colour. Some antifreezes are pink but I'm not sure what they are...

If in doubt, use the same colour again or very thoroughly flush before refilling...

Jim's right - there is no standardisation for coolant colours, although "long life" and OAT (organic acid) types tend to be red/pink/orange, and glycol types tend to be blue or green. But never assume, and don't go on colour alone.

If in doubt about the make and type already in there, flush out thoroughly and replace. Put a sticker/note on the engine to show what you have used, and do any topping up with the same stuff.

I flushed the system four times, including opening the drain on the engine block and added blue coolant
