I have a 1999 Chevy Malibu 2.4 4cylinders. Recently the coolant light came on. I filled the reservoir and also put in Stop Leak to get me by until I can afford to get it fixed. Well the other night the car overheated. The reservoir was still filled and the car was smoking. We figured out that the water outlet (not the water pump and the thermostat) was broken. We replaced it and I thought it was fixed, but it overheated again on my way to work. What should I look at next?
