Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.I would start with having a block test performed to at least rule out any possibility of a blown head gasket. If the block test checks okay then I would suspect you may have some trapped air in the system which can cause poor flow through the system and would likely explain the difference in the heat on the two hoses.
Okay, Im here if need be.
