Coolant

[Lance Evans]

How often should you have to top up coolant 

[Magnet]

Maybe a really small amount ( or nothing at all)  at an annual service Lance.

How much are you needing to add, and over what mileage/time? 
Kind regards,

Gareth.

Topped up once in 12 months hardly anything

i believe mines leaking slightly at the water pump.all pipes look good.(will find out soon when i do the timing) never needed topping up before this happened regards stephen
