So I've noticed the past couple of days that when I park in my driveway, the cooling fans continued running after I shut the car off, even though it's not terribly hot outside. Then today, I was at a stop light, getting ready to turn in to Costco to get gas and I got a warning that the car was overheating so I turned it off until the light changed and kept it turned off in the gas line, except when I needed to pull forward. Once I got my gas, I pulled around to a parking space and checked the coolant reservoir to find it almost completely empty. It usually stays half full. I ran in to Costco, hoping they sold coolant but no such luck. I was pressed for time because I was supposed to take a friend to get outpatient surgery so I just stopped off at NAPA and grabbed a gallon of Peak 50/50, 'mixes with anything' coolant, dumped a little more than half the jug into the reservoir and went on to my friend's house. The surgery center was about 15 miles away from my friend's place and about 35 or 40 miles from my house and I didn't have any more problems. When I checked the coolant level later on, it wasn't appreciably lower. I'm going to check the driveway in the morning to see if any coolant has dripped. I've got a very busy week coming up so it may be the following week before I can get it to a shop to be more thoroughly diagnosed.
