I've noticed my Coolant tank running low after a few miles...It was on the "low" mark and I refilled it to the "max" line just a few days ago and now it's to the low mark again after about 50 miles..is this normal or is this indicative of a leak somewhere?

Is it running hot? Do you see bubbles rising in the coolant reservoir? It could be a leak somewhere. Pull the dipstick and look at your oil. If it looks like a chocolate milkshake, you've found the missing coolant. If it looks normal, light it on fire. If it sputters, you have a little water in it. If everything appears normal, have a shop pressurize the system and look for the leak.
