Replacing the Jägermobile Water Pump Again!

[AKnowles]

Jager, for my two cents I would not open the reservoir while it is hot. Before I bought my uvIew Airlift 550000 for the vacuum bleed I did several flushes using just distilled water. Anytime I tried to open the reservoir there was venting. Even with the purge valve open. I'd recommend letting it cool. Doesn't have to be completely cool, but can't be at operating temperature.

If you are in Southern CA, you are welcome to stop by and use my vacuum system. After my first fill, and running the motor, I let it cool down and created a vacuum again and added another 1/2 gallon using the system. Since then it has been running at normal temps. I seriously recommend buying a vacuum system for the coolant flush or water pump replacement as it works very well and eliminates the need to bleed the system.

Thanks... I will run it for a couple days, wait for it to cool-down, then close the valve.
Thanks for the offer... I think I am in Southern CA? But they call this the "Central Coast", I'm in Santa Barbara county.

What sort of noises and symptoms indicate the pump failing.

Reason I ask is because I hear a bit of a rattle when idling that I think is new and my guess would be the pump bearings or the timing chains.

It even does it when hot so thats probably less likely the timing chains?

Would I see coolant loss over time if its the pump bearings?

My car has ~65K miles on it and still on the 1st pump I think.

Take a look at my thread describing my symptoms prior to the failure. Maybe that will help ...

My original pump started having grinding noise (at ~202,000 miles) and then started to leak a little, leaving a spot on the garage floor, and I replaced it with a LASO. The LASO pump starting to fail (after 40,000 miles) did not leak but is started to make noise that I can best describe as one of those old crank sirens (not as loud) being turned at a slower speed and increasing pitch as the RPMs increased.

Jager,

That would be quite a drive to Palm Desert, CA. But if you need it let me know and I'll mail it to you.
