Puking coolant

[gamli]

My 1994 E320 pukes 1-2 liters of coolant when stopped plz advice

If it is not running hot it may just be a bad cap on the expansion tank. If it is running hot try a new thermostat. How does the coolant appear? Is there any sludge or oil in the coolant? If yes, then it is likely a cylinder head gasket.

A new thermostat will do nothing for an overhating engine (unless the tstat is stucked closed which is unlikely).

Respectfully disagree... a thermostat does not need to be stuck closed to cause overheating. Thermostats often open incompletely causing a warm running condition up to the point of overheating due to a restricted coolant flow. Have seen cars run warmer than normal under certain conditions and normal temps at other times. Replacing the thermostat solved the problem.

Good luck!!!

Thermostat is new, there´s no oil in the water but I´m not sure about the cap on the expansion tank will get me a new one, thanks.
