I have a leak coming from the water pump that flows down on the side of the AC compressor before landing on the ground. I cannot verify exactly where the leak is coming from on the pump, but I am sure it is the pump leaking because it also sounds bad like rattling. My question is do I have to remove any other components, such as the AC compressor to be able to remove the water pump. I would be great full for any suggestions.Regards,Steph
First you have to mention which E320 you have. It could be either a gasoline or diesel model and the E320 model designation has had the M104 I6, M112 V6, M613 I6 diesel, and M642 V6 diesel under the hood. The water pump is not located in the same place on all engines.
1. Disconnect the Ground Cable. 2. Drain the Coolant. 3. Remove Fan Shroud. 4. Remove Fan Visco Clutch. 5. Remove Radiator Hoses and Thermostat Housing. 6. Remove the Serpentine Belt, pay close attention to the path of the serpentine belt. Suggestion draw a diagram as to it's path, before removing. 7. Remove the Water Pump Pulley and Power Steering Pulley. 8. Remove the Tension Adjuster Mechanism. 9. Loosen the Power Steering Pump and move it to the right a little. 10. Remove the Water Pump, and you're done. Tools Needed .... A nice Stereo, plenty of Beer, and a couple of friends to keep you company. Good Luck !
