Hi All Just dropping to say hello. Have a 2007 300C 3.0L CRD, very pleased amazing car, few issues that gradually dealing with but the most urgent one is think my water pump has failed, anyone got any experience with changing one on the CRD, found lots of videos for the 3.5 petrol and 5.7 Hemi but nothing from the diesel CRD. Any help gratefully received. Regards Keith W
