pukes after parking

How many of your cars spill coolant out of that little overflow tube in the radiator neck when your car is parked and turned off? Mine always does this after a long drive. Is this common, unhealthy, or a sign of an engine that is running to warm?

Sounds like you need to decrease the coolent level in your rad just a bit and the problem should stop. That or your rad cap is shot.
Do you keep it "full" ? Mine will do this if the radiator is filled to w/i an inch or so of the top or higher.

There is no problem if I fill it (cold) to just cover the core by 1/2 inch or so.
If it wont stop, even if you dont add any new coolant, something is definately wrong... .

I once had it (a lot of overflow after real short trips). It started real sudden, and was really bad.
We tested the coolant for Co2, and it showed that there was Co2 in it. So that meant there is a leak!
After all we tore the engine apart and replaced all major/upper gaskets.
Since then everything works fine again, well kind of. (knocking on wood).

In my case it must have been some faulty/broken engine gasket... . /forums/images/icons/frown.gif
NOT FUN.

Hope its not as serious with your car.

Mine does this too if the radiator is filled all the way to the top. Mine runs just a tad warm (a little past the midpoint on the heat gauge) but I don't know if that has anything to do with it or not. Hopefully nothing to worry about /forums/images/icons/smile.gif
You either need a new radiator cap or a stronger one. Mine was puking with a 13 lb (stock) cap and it stopped when I put an 18 lb cap on.
