Water Pump Hose Question

[Chuck W.]

I am gathering all of the parts and fluids to change the water pump on my '01 Boxster S, 25,000 miles.

I am going to do the pump, thermostat (low temp), belt, coolant and the hoses at the water pump. I have found the part numbers for everything but the water hoses.

Are there certain water hose(s) that should be changed while I am in there? I was also considering changing out the motor mount to the 987 one while doing this. Thoughts? TIA

Not sure of the P/N's ....sorry.

First off, I did my WP/thermostat on a lift a few months ago. It was a very easy job.

I had already done my motor mount and because of that, knew it was easy to remove and would facilitate making the WP job easier. If you go that route, go ahead and replace the mount. I doubt its bad at 25K miles but at 45K, I doubt it'd be any good! Of course, the way you rack up mileage, 20K miles might take you another 20 years!

FYI,
I loosened the upper WP bolts from inside the car before raising it up. I also remove the belt.
After getting the car on the lift and the coolant drained, I supported the motor and removed the motor mount. If you are replacing hoses, This would be the time to remove the old ones.

Loosen the remainder of the WP bolts and set them down in their correct orientation.
Remove the pump
Remove Thermostat

Wash, rinsem repeat.

FYI, my WP had 122K miles and I had a slight leak. After inspection on the lift, the leak appeared to be coming from one of the bolts. Given the low torque for WP bolts, I'd bet I could have retorqued and been done.

The WP bearing showed no play and spun easily. all the vains were in tact as well.

When replacing your sertentine belt, spin the roller bearings and alternator to check for noise, play.

I recently did these, too, plus the motor mount and had a thread about this with tips from other people as well that might be useful to you.

My car was at 135k miles, and the motor mount was absolutely worth it, or necessary. The old one was extremely disintegrated.

My first mistake was not raising the front end to drain coolant from the radiators, so I had to redo that part. Also, I followed the manual coolant bleeding procedure (Bentley, Pedro's Garage) the first time, but didn't get certain results. I actually bought the Airlift kit and redid the bleeding. It was so much easier and faster with that tool.

Anyway, good luck with the repair!

Curious if you were thinking about going with that Evans coolant?

Thanks.... Yeah,,, I've been digging deep in the web and have read a ton of threads with some great info. I am buying an Airlift too. My brother has a Boxster too so he will use it on his too.

No. I am going to stick with the Porsche coolant.
