Thanks again ToolP, I will do my best not to get burned.

The new pump has the metal impeller and I did not take a picture of it before I installed it. Sorry about that. I will take a picture of the old one and post it for you in the am when I get out to the garage to work on it.

Thanks again ToolP I bled it like you suggested and so far so good no leaks. I used distilled water and I will drive it a little tomorrow morning and see how she reacts. If no leaks then I will flush and fill with proper coolant.

The temp ran a little just past the 180 mark on the temp gauge, the fan came on and off. Topped off a little and put down the bleed valve and closed her up. The warning light was blinking the whole time while I was bleeding her. Am I to assume that is normal since I did all of this while the car was in my garage? Door open of course.

Here are a few pics of the old water pump

The blinking light is because of the low level in the tank. If you fill the tank up to the max while it is blinking and the engine running it will continue to blink. But once you turn off the car and start it up again the blinking stops.

If you did not get all the air out then, as I said, you can drive around with the bleed valve open for a while. If you see the level going down a bit then you know there was still some air that has come out and replaced by the coolant.

Can't see the first 2 pictures. The pulley is cockeyed and wonder if the impeller took a hit.

Any indication on the pump or packaging as to who makes it and in what country?

Thanks again for all your help.

It looks like the bearings went out and then the plastic impeller got beaten up pretty good.

I did not see any obvious label on the pump. I did see a small marking that says SEM on it. I edited my initial post. The pics should be better now.

I wanted to replace the hose that connects to the water pump but as usual Braman Porsche ordered the wrong hose and their excuse was priceless. "We don't know we usually just swap out the part when the tech brings it to us."

Do you know the part number for that hose?

I looked at PET and see why the wrong hose was ordered. There is a page of spaghetti hoses. A diagram of every hose in the cooling system and then the poor parts guy has to figure out which one go where. No written descriptions. And of course the water pump is is on a different page. I do not want to guess at it either.

If you want to get under the car again you can look for a part number on the hose. Or, just leave it alone.

As for the impeller on your old pump. It went bye bye.

One of your pictures.

Thanks again ToolP, I took her out for a short drive on Friday and she had no leaks but ran a little warmer than normal. There was no smoke or leaks as I found before I bled her. Am I correct to assume she ran a little warmer than normal is because I used distilled water?

Once I get the hose replaced I am going to flush the coolant and replace with coolant and she should be back to normal. BTW is this the hose that connects to the water pump from your picture below?
