You shouldn't need to be contemplating topping up the coolant. If you are needing to top up then there's either a leak or you are over-filling it. I never touched the coolant in over 4 years of owning the hybrid and, as far as I know, it didn't need topping up during the annual servicing.

Agreed. I have never touched my Hybrid under the bonnet except for topping up the screen wash. Regular services takes care of the rest.

Having owned various Jazz's for nearly ten years none have ever needed topping up with coolant.

Half way between high and low marks when cold is adequate.

Have to agree with other posters as I have never had to add anti-freeze to a Honda. But here is some anti-freeze info.

All antifreeze mixtures contain ethylene glycol which is the 'anti freeze' bit (which never wears out), the OAT (organic acid technology) and HOAT (hybrid organic acid technology) are the anti-corrosion chemicals that keep the system free of corrosion and gunge (this is the bit that wears out or gets used up over time), modern anti-corrosion additives last at least 5 years under normal use, Honda say the original OEM fill should be replaced after 10 years from new and then every 5 years .

You can basically ignore the colour of anti-freeze it is only there to show up a leak in the system and each maker adds their own colour to basically the same chemical mix. I have used silicate free OAT premixed 50% from Halfords ( http://www.halfords.com/motoring/engine-oils-fluids/antifreeze/halfords-oat-ready-mixed-antifreeze-2-litres ) in cars and motorbikes. Anti-freeze containing silicates is not suitable for modern engines and can ruin your water pump and seals in short order, OAT and HOAT is long life and compatible with mixed metal systems. ( 2 litre bottle for top-ups - for full system change buy 5 litre bottle)

Buy pre-mixed 50% concentration with distilled water, as this gives best protection, below and ABOVE this concentration actually gives less protection against freezing (so its not a case of more is better).

if you search antifreeze on this forum there is quite a lot of information.
