Review on Improved Beck Arnley Water Pump - Model 131-2130 by John Stefko

Fits my 2006 BMW X5 3.0 The thermostat failed and I decided to replace the water pump while removing the fan and cover as it is a mechanical part, which is prone to deformation and failure. I did some research and chose Beck Arnley over AC Delco and so far I have no regrets. It has been running smoothly and in a few weeks of operation so far there have been no leaks or heat issues. All metal construction and bearings feel solid on the new part. I was glad I decided to replace it along with the thermostat because after pulling out the old water pump I found that it was the original 2005 stamp and the bearing wobbled a bit.
