Question, my daughter has a 99 New Beetle. When she is out driving everything is fine. But often when she shuts it down after it gets warm. The coolant purges from the reservoir.
I can watch the level come up on shut down. Die to the water hearing up from not circulating (engine off). But I would assume the pressure build up would be accounted for.
We've replaced all the plastic coolant bits around the engine, water pump, thermostat, radiator, and radiator cap. Hoses do not seem to leak and the return hose does not seem to be blocked.
Does anyone have any insight?
