SSM 47347

Some 2013-2017 C-Max PHEV may exhibit diagnostic code P2183 and may have the coolant hoses that attach to the lower bulkhead connections incorrectly installed. The two hoses share the same female connectors and mate to matching male tube ends. There are two primary methods for telling which hose is which. The hoses have a marking on the upper surface (when installed) for either inboard (IB) or outboard (OB) orientation. The other method is to observe the braided protective sleeves that are installed on the hoses. The longer, nylon sleeve is on the inboard hose and should be attached to the tube that is closest to the driver's side. The shorter, fabric sleeve in on the outboard hose and should be installed to the tube that is closer to the passenger's side.
