I've noticed that in cooler weather, I can see steam coming from the front of the car. Every time I pull over and try to locate the source of the steam, it's gone before I can open the hood. The radiator doesn't have a cap like most cars. The coolant level is always the same and doesn't go down.
What can I test for? Radiator pressure test? Or is it just the zetec engine running so hot that the moisture from the headlights and hood is vaporizing? My car is a stock 98 Mystique zetec ATX.
Thanks.
