Cooling System Maintenance ?

[Paul]

OK, I'll try to stay on point, it's just been fun so far.

Here's some of my thoughts:

I doubt you will find many Porsche owners that have tried this process since Porsche says our coolant is good for the lifetime of the car.

Water pumps fail sometime between 75K and 125K, change the coolant then.

I doubt this process will remove even 2/3 of the coolant.

The level of vacuum used in this process may temporarily collapse most of the radiator and heater hoses.

BTW I used to be an INDY.

Paul,
Finally! A technical opinion. All good points, as well. These are the type of considerations I was hoping for, a few posts ago....

You HAVE been having fun, haven't you. Up to this point, you had me believing that I was corresponding with Yonnie Yonson, from Visconsin...

Email makes it so difficult to fully appreciate dry subtle humor, sarcasm, leg-pulling, etc. Particularly that bit about "Porsche says" and "lifetime coolant". Those are two real knee-slappers, now that I think about it.
