Just curious, does our E36 have an overflow cap. because when i got my water pump changed, they obviously topped off my coolant, but I've noticed after driving it hard (new suspension :-D had to take advtange of it)
that the coolant had dropped some at hot level.
im assuming that when they filled it up the coolant was cold, and my "spirited driving" and plus the coolant raises when hot. so im assuming somew would go through the overflow cap?
just checking to see if it had an overflow cap and my situation makes "sense"
