I have a 2000 Boxster S.
This will be my third in 70K miles. Not so good. WOW, it seems that both the pump and thermostat seal up with a steel gasket and no gasket sealer or silicone. Is that correct?
Also, I seem to have the bolts all mixed up. There are 5 all the same length, and two long. Those appear to be for the two sleeved fittings on the pump housing--the short little fitting sleeves on each side of the pump housing. Sound right?
I'm not so confident I can seal that without a leak, but I'll try.
Can I use the Bentley method to re-pressurize, without buying that special tool I'll never use again? The Bentley manual says that you just flip up the bleeder lever, protect the trunk carpet with towels, run, rev, fill, run fill, etc. Can I do it that way or am I looking for trouble.
Thanks all.

... correct torque values, the metal gasket is all that's needed.
It won't leak.

Just to bring this thread along:
Now that I've got my new water pump installed, and having searched everywhere, I'm concerned that I couldn't find the little chips off my old impeller. I'm curious why they didn't drop out with the coolant. I'd think that chipped impellers are common. Where do they go? They're also not in my thermostat housing.
About the torque on those seven bolts, I actually was able to get to 5 of them. I torqued to 7 lbs. So, on two I had to guess. I'm not comfortable dropping the engine mount to reach the remaining two, and not sure I could even then.
And, by the way, would it be correct that using a flex-socket with a torque wrench would distort the values?
Oh, I guess I'm mention another thing. That new pump of mine has a slight "ringing" to it when I free-spin it. I hope that's just the bearing without the lubrication from the coolant. I hope.
