[Green Maestro Man]

Hi all -

Have noticed coolant/antifreeze in my Maestro is low - but can't tell where the "fill" mark is (i.e. how full to fill the reservoir) - normally it's 1/2 way up the tank in most cars I've driven - but just want to double check that it is the same in a Maestro...

Thanks

It has a a dimple (by dimple, a round hump you will see it when you look) iin it, fill it up till the coolant/water just gets to the top of it.
