Electric water pump failures...
#16
The pics on that link for the LED don't work, but it sounds like the LED only tells you when the circuit has power, not necessarily when the pump is running. Big difference. If the pump motor fails but still has power, then the LED will stay lit. Hooking an LED up to the pump side of the relay (motor red wire) could, however, tell you if the relay fails.
about the only REAL way of telling the pump is running is to install some sort of flow sensor. this actually reads whether or not the coolant is actually circulating.

don't get a csr/csi, thay have a poor design which causes the force of the water to spin the impeller off of the motor shaft and wedge against the housing. A simple change in thread direction would have been due, great engineering there anyway this happened to me and i just said screw it and bought a meziere.

Daily driver here and never had one fail yet... not completely fail anyway. The bearing on my CSI started to get some water in it and you could hear it struggling but the pump still cycled without blowing a fuse. That pump had at least 30k on it and probably well over. The new pump now has 20k and is still going strong.
I like them but they can have obvious reliability issues... electric pumps either work or not while mechanical pumps always work even if the bearing fails.

And how many times has your pump lost its connection and overheated your car? Your old pump really did sound pretty bad too but it kept on going. You should put it back in and see how many more miles you can get out of it.

Just run what you feel comfortable with. If you are one of those guys who get freaked out over little things that may happen, then stay stock. If you can handle the thought that the pump may fail without you knowing until the temp starts to rise then go electric.
Before I start my car I just turn the ignition on and listen for the hum of the pump. If for some reason I don't hear it I will actually open the hood and listen for it. I'm also constantly looking at my temp.
I look at it like this, it's a performance car and every little thing I do to it will and can make it just that much more unreliable. If I wanted full on reliable I would have left it stock. What fun is that? I'm on my 2nd Z28 and they have both had a CSI with no problems.

For those guys that think the mechanical pump is more reliable. I'm the original owner and have 140000 miles on it. I have had 2 mechanical pumps fail at 60,000 miles and 120,000. It not a problem as long as you watch your temperature guage. I will never go back to a mechanical pump. Meziere takes only 10 minutes to change if it fails. However I have not had to change it.

Have you done this before? I'm wondering how easy it'd be because mine is really close to the fan- looks like I might have to remove the fan even to just swap the motor out.
