probably worrying about nothing here!!
ive noticed every month or so the coolant level seems to drop ever so slightly below the kalt mark,
ive had the waterpump done about 2 weeks ago and its dropped slightly again today,
trouble is i park on a slope facing down so its really difficult to get a reading when the engine is cold,
is it possible since doing the waterpump there could be an air leak or something causing the level to drop?
