coolant

G12 needs diluting 50/50 with water, thought the whole system was about 6 Ltrs?

Might be wrong with the last bit though, wouldn't mind a definate answer as I'm putting my new radiator on next weekend!

6.3 litres

ive just bought a bottle of coolant from tesco, its tesco's own summer coolant, i have just been topping up my exspansion bottle with water in the past and i thought that this tesco's coolant must be better than water,

is it ok to just top it up with the tesco's coolant or should i drain all the old water out?

is it ok to use water ? im not sure wot was in the car when i bought it, but ever since ive just used water

i'd flush the system and use the pink halfords stuff, it's pretty much the same as G12. that way it'll get rid of the old stuff plus the tesco mix

[gtiscott]

what do you do to flush the system?

buy some rad flush. They all have different instructions so i couldnt tell you how do do it. Go for the powder stuff  you can put in the expansion bottle rather than the gritty stuff that you can only put into the rad
