Had a new radiator fitted last week as mine had a crack in it. Had new coolant at the same time but must still have a leak somewhere (or the garage didnt put enough coolant back in) as im just setting off on a little journey but when checking fluid levels the coolant is below the min mark! Is it ok to just add a bit of water to it for the time being? Just havnt really got time to call anywhere to get some, plus i know your not meant to mix coolants. Quick response appreciated guys :)

yeh just water is fine, it's ok to run just water most of the time, coolant just aids it in working

Cool cheers. Damn just added water and put more than i realised. Its about an inch and a half above the the max mark! Will it be ok still?

yeh that will be fine, theres an over flow pipe on all cars to allow the excess to be dispersed if need be

Make sure you put some Anti freeze in though too but water is ok until you can :)

I'm guessing the garage didn't allow for the coolant to run around all the pipes and fill the rad. So might need bleeding too I would maybe ring them and ask just so they know about it. they might have just over looked it if they was busy.
