T1N Molded Cooling Hose, MB [OM612]

Original Mercedes Molded Hose for OM612 engines.

This hose is for om612 (2001-2003 US Market) ONLY. It is the "S" shaped hose that comes off the back of the head, winds it's way though the intake manifold and connects to a plastic tube/fitting as it exits the intake manifold (shown in photo above). It's hard to see and even harder to access, so it's easily forgotten about when checking and changing out cooling hoses. 

Because it comes straight out of the head, the coolant that passes through this hose is extremely hot. Under normal circumstances, this is not a problem, but if the engine has been over heated or has a head gasket leak, the coolant passing through this hose can be so hot that it begins to break down the rubber in the hose, causing it to degrade and leak. Therefore, it definitely should be checked.
