2002 Mercedes-Benz C230 Q&A
2002 Mercedes-Benz C230 Question: How do I know my car has a cracked head?
I had the head gasket changed, as well as the thermostat. There has been no definitive test as to why I am losing coolant. The dealer had my car for a week, and they tell me "it must be a cracked head. We can't really determine for sure until we open up the head". I don't understand the answer, as they should have seen this when they changed the head gasket? Pressure tests show nothing. I am losing coolant still. - NJGirl
the head should have been sent out and check for cracks and warpage - goodguy
This should have been checked before replacing the head gasket by either the repair shop or by sending the cylinder head to a machine shop. standard proceedure when replacing a head gasket. - Dave Gomes
