After a brief drive to work this morning I noticed a ton of steam pouring out of my grille while idling in my parking spot. The roads were wet from rain so I'm thinking it was just some road spray burning off..but the steam came out for a while and there was a lot of it. It looked like my car was overheating badly. My girlfriend had to take the car to school so I told her to keep an eye on the temp gauge. The gauge never passed 1/2 way and she told me the steam stopped after she reached school. The car just turned 4,000 miles and I've had some problems with it..like replacing the power steering pump..Any ideas?
