Thread: Another water pump failure

judging by the state of the impeller am wondering whether rota virus had a bearing on it

It is a different vehicle and a different motor, but my water pump failed in exactly the same way.

There were no leaks and there was no noise until the bearing collapsed and coolant leaked everywhere. I had only just started, the engine wasn't even up to operating temperature and I stopped very soon after hearing strange noises. So there was no overheating.

I think it was probably the original pump. The failure occurred somewhere around 120,000 km.

Dunno. I thought Quinton Hazell was good but I'm now told that may not be the case.

Rebuild, no, I'd say not possible. They were once upon a time.

I couldn't press the impeller off today so I cut it off. This is what was revealed.

If you could dig a little deeper, I would be interested to know whether that old water pump had a plastic cage around its rollers.

Once I eventually pressed the shaft out, it was a bit hard to tell - not that I looked. It is possible now that I think about it. Unfortunately, I've binned the bits that came out.

If I recall correctly, the rear bearing was roller, the front was ball.

they don't make them like they used to.......

The car didn't over heat at all?

No, I think it was OK, John. I'll take it for a drive tomorrow.

Interesting on the pic is the rust on the impellor top coming from shaft. What coolant are you running?
