You are correct KPM, I did make a mistake on the price for the new water pump from Napa. Their web site says it is $154. I think my local store quoted me the $158.

So the question is still unanswered. Has anybody tried one of these from Napa ?

Will I be the first to do so ?

Also, Please help me understand the reason the 160 degrees thermostat is better than the 190. It is my understanding that an engine not up to at least 180 degrees does not opperate at peak efficiency. Give me a little more detailed information so I can give my car the best treatment too.

So, if I get the gist of this thread, we replace the water pump with a Porsche OEM pump (plastic) impeller (JTP) every 2-3 years (Jake).

Well, I guess I am due to replace mine (4 years). Who has the best price on a new OEM pump. My Boxster is a 2007. What do you think it will cost me to have the dealer replace it?

I know this has been said many times before, but also look at changing your front motor mount at the same time.

Yes......I keep hearing this and always wonder what the deal is. I suppose there is a huge polymer section to it and it is susceptable to embrittlment over time? I am at 11 years and have never felt anything like the engine shifting around. I guess I would have to be out of the car and maybe have a look. Is there a 997 upgraded mount that all are using? Is it fair to say that there is no additional labour in getting at the mount while you are at the pump? I would like to do these myself if they are feasible using jack stands....

987, not 997

I just had my water pump changed on my 01 box with 37k km.

The plastic impellers were still perfect, the pump seems in pretty good shape.

But at least now I've gotten rid of one potential problem...

Also had the low temp thermostat put in.... temperature is now usually slightly above 80 degrees C, goes up to approx 90 degrees when pushed hard (same as prev). No other noticeable difference though.

I changed the serpentine belt at the same time, although it still looked good. And was very glad I did, got rid of the whining noise especially when the weather is cooler or engine is cold..
