Hello everyone, I have a 2005 CLK320 that was involved in a minor front end collision few months ago and was repaired at a reputable body shop. couple of weeks ago, i started loosing coolant fluid when I turn the heater on. I found a pipe above the windshield washer bottle that was not connected to anything! This pipe will drain coolant fluid for 15 seconds or so when the heater is turned on and then it stops. I can't find any other connection where this pipe might connect to, So I capped it temporarily until I find out where does it go to. Does anyone have a diagram of the cooling system that shows the pipes and hoses and how they're connected together? Thanks in advance for any help.
