So the weather has been hot and cold and last week there was a small drop of coolant.. right side.. I wiped it off and drove around. One more drop. Now today i wiped Off the bottom to make sure no liquid was on the car. Ran the car for 15 min sitting there. No coolant on the ground. Checked 2 hours later to see if any would be there.. still no coolant. The car is going in for annual Tuesday but has anyone had this happen?
