Water pump failed - got stranded

[Quadcammer]

your concern is that the impellar blades cracked off and are wedged in the head or oil cooler. If your blades are accounted for or a bit scored but not gone, you should be fine. If water is pouring out that easily however, that likely means the bearing was cooked and you may have had quite a lot of wobble on the impeller. Won't know till you get it off.

If no issue, then install new water pump, get the ass end of the car way up in the air, open the bleeder, pour in most of the new coolant till tank is full, run car, hold revs at like 2500 until thermostat opens and then continue filling.

Drive for next few days with vent cap open, top up as needed, and you're done.

Before failing, for couple of months there was a "diesel like" engine nocking sound, coming from the water pump.

1) get the ass end of the car way up in the air -> Really needed ?
2) run car, ---> Start the engine with Bleeder open ?
3) Drive for next few days with vent cap open --> Vent cap you mean the bleeder or the Coolant vent that i fill coolant into ?

If the car is hot and the coolant vent cap is open, isnt this supposed to be bad ? I remember they say never open the coolant vent while car is hot


Thanks!

Or, if you can afford/justify it, use an Airlift. They really are as easy to use as the youtube videos show. I can't imagine doing it 'old school' now.

I prefer the old school for now. But I don’t know how

+1 on the airlift but doing the bleeder valve way can work.
Rear up high is to get air bubble to travel out of radiators to highest point, the Bleeder valve.
Fill cap tight, Bleeder open

+1 on low temp thermo

When I did mine for preventive maintenance, I flushed a couple times with distilled water then final re-fill with Porsche Pink

Good luck and hopefully your old WP didn't do any damage

might as well replace the thermostat with a lower type of 160 degrees.

This. Exactly this. Don't overthink it.
