^^as above - your 172 will prob have decent stuff in already so a little dilution wont hurt! Could also get a small bottle from renault....cheap enough (sub £10 i think)
there are different types of coolant and some dont mix, so dont just put anything in, yours should i presume have the Renault stuff in it, so id go to the dealers and buy that
You should check coolant when the engine is stone cold.. it should be on the MAX line when cold and rise roughly 1cm above the max when hot. Use renault stuff as you know its correct.
