I had to remove and replace my Rover's water pump today. Fitted in 2008, this pump was easily the longest-lasting and most reliable pump that I have used covering 202,286 miles (325,680km) in 14 years. The bearing has not failed, instead, the seal was no longer preventing coolant loss. The tell-tale sign of coolant exiting from the warning hole being the indicator. I fitted another new QH pump in its place. I hope this one too serves just as well as its predecessor. I used Penrite Pro anti-freeze anti-boil at 33% concentration, then Penrite long life coolant at 50% concentration from 2015. I have always used Loctite military specification anti-seize on the bolts which prevent corrosion. The bolts all undid without any undue effort and no shear failures to report.
