Every time I turn my car on I get a white steam out of my exhaust pipe along with water dripping out of it. We just had to replace the water pump and the thermostat. The car had no antifreeze in it when I bought it (about 2 months). It got cold so I was unable to flush the radiator. We did it when we replaced the water pump (about a week ago). Could it be the head gaskets?

Hi there,

If you are not using coolant nor overheating don't worry, the combustion process produces a large amount of water, with the engine & exhaust cold this water is condensed back into a liquid and this is what you are seeing, with the engine fully hot you should not be seeing any vapor, just check that your coolant is not going down first.
