It has happened a couple of times when parked or just stopped. The engine decides to blow out a few ounces of fluid. The steam appears to be water. Is this common or should this go to the dealers?

 

If it is happening when it is raining it is completely normal. Mine does this whenever moisture comes through the grille.

 

Sometime, it comes from the catalyzer (Chemical reaction) Nothing to worry
Sometime, it's condensation inside the muffler

 

If i'm understanding what your getting at here, you mean the steam rising up from the front end? Say after it's rained, you've washed it, or gone through a puddle??

Wel thats just water evaporating off the hot radiator up font....but if thats not what you meant then I'm not sure
