What's your shop so I know never to go there.

My shop only services customer cars that I choose.

In any case, I only use it in my personal fleet mainly for topping off.

In any case the OP will need 3 gallons of Porsche Antifreeze ($28 each at my dealer) mixed with 3 gallons distilled water.

Total capacity is 5.89 gallons if you have a manual tranny, 6.42 for a tip.

Paul, really? 6 gallons for the Boxster?? That's twice the coolant capacity of my Ford Explorer.

Do dealerships and indy shops really have distilled water laying around for these projects?

Hard to believe until you consider your car has 2 radiators, a water cooled oil cooler and at least 20' of 1 1/2 inch tubing/hoses. A quick look at your owners manual should satisfy any doubt.

I guess good shops use pure water.

Thanks, Paul.

To others, I am not buying this "replace the water pump" early notion as a wear item. I asked one of the largest discount Porsche dealership parts departments today about this, and they told me the following:

In 2009 they sold 5 water pumps for the 987/997. They sold 9 in 2010.

For the same periods with the 986/996 they sold 53 and 71 respectively.

I'll either wait for it to brake and replace it, or wait till the car is a little older, like in 2016.

I replaced my coolant two years ago when I updated to the LN low temp t-stat...wish I would have done the water pump at the same time. As stated, if the impeller breaks, tiny pieces get stuck in the cylinder head and cause major issues. I've seen it happen to some friends and it's enough to scare me to change mine as a precaution.

Water pump failure is not a 986/996 issue. Every car made has a water pump replacement schedule. It's usually done with the timing belt (when there is one), which is typically 45,000 to 75,000 miles. Again, this is all cars. 944s are largely changed every 30,000 miles.

I think that's true of any shop, no?

Perhaps, but I closed for business years ago, just fool around now in my spare time and to help friends with their cars.
