Changed Water Pump and Engine Mount

I did some preventative maintenance today, replaced water pump and engine mount. My car is a 2000 'S' with 56k miles. Messy job at times draining the fluids. Here are my observations:

About 4+ gals of coolant came out, it was very clean and orange in color. I put back in exactly 4 gals so I'm guessing there was probably .5 gal still in the front of the car. Since the old stuff was clean I didn't tilt the car to try to drain from the front. I was concerned about the process to burp the car but I followed the steps in Bentley and it worked out well. I left the under panel off during the process to watch for leaks.

Removing the water pump was pretty easy. The 7 bolts were torqued very little and came right off. Be careful not to tighten them too much with the new pump, 7 ft-lb is not very much. The old pump was like new (see photo) below. The only difference was the bearings make a little noise in the old one. No play at all and fins are like new. Is the old pump something I could sell or just hang on to it?

I found the engine mount to be the hardest. I have to hand it to those that change it without doing the water pump at same time. Being able to move the radiator hoses out of the way really helps. Job would have been easier with a few more quality tools. Old engine mount was starting to crack on two sides so glade I replaced it. The torque amounts putting the mount back on seem like a lot but maybe because laying under a car doesn't give much leverage.

Next job this fall with be the big one, clutch, RMS, IMS.
