Even though it didnt make you feel the greatest, a $35 fee is a small price to pay to get you back on your way with no issues........Make sure you do a thorough job when you clean out your coolant and rinse and flush several times before refilling with coolant. I hope that this stuff hasnt eaten away at your radiator or heater core too much already....... good luck the rest of your trip.........when are you supposed to arrive in vegas?
