Yep, it shows the density of the fluid. which is the limit of the coolant's capacity. Ideally, it should show -35 to -40F.
No less than a 50/50 mix Ken. If you live where the temp is REALLY cold, you can get away with a 70/30 mix, (70% antifreeze and 30% distilled water),
Don't overfill the coolant reservoir as it needs room for coolant expansion when the coolant is at the engine operating temp.
Only fill it up to the FULL COLD mark. When hot, the level should be no more than 1" to 1-1/2" above the cold mark.
Best time to check the level is in the AM before the engine is started.
