2003 Mercedes E320 (W211) Aux. Water pump failed...

Question by larrylawrence posted 5 months 3 weeks ago in 2003-2009 (W211)

Hi guys! USAF Major Lawrence here. We have a 2003 Mercedes E320 (W211) as an embassy unofficial get-around car. Recently the auxiliary water pump started making noise (impeller sounded like it was rattling around inside) and shortly thereafter developed a water leak. Our carpool mechanic is pretty dexterous and disassembled the pump and the impeller is very worn, yet no sign of leakage from the sides. It is the bottom area where the water seems to leak from but I could detect no fissures or cracks on the body of the pump. I am in Venezuela without hopes of finding another pump for a couple of months. Thus, my question is: can I bypass (maybe with a pvc elbow) the pump safely until I can replace it? I am in tropical climate and will never require heating. How would this affect my car? Notice please I wrote SAFELY. I would not want to damage the car because it would mean being forced to always go out in marked embassy cars and us gringos aren't very well liked by the Venezuelan government. No need to make it easy for them to tag along on all our outings. I solemnly appreciate any help on the subject! Maj. Lawrence - out.
