How Often Coolant changed ?

[michaelg]

Excuse the ignorant question

How often should the coolant be changed ?

I've no idea when my 02 was last done, had a small leak a few years back and a bottle of Novastop sorted it.

While we're on the subject of fluids , how often gearbox oil ?

If you work on coolant 5 years and gearbox oil every 50k you wont go far wrong - the specs do change between manufacturers and oil companies so its a bit of a grey area.

Citroen give no guidelines for either of your above questions which is not unusual.

Blue antifreeze is two yrs, red or green antifreeze is 5 yrs, and gear oil is generally changed when the clutch is, harder you are on a gearbox the quicker the clutch wears out generally...
