Coolant service done with Vacum device

That one in the shop probably costs around $4k-$6k cause its got this panel with levers that divert vaccum to other tanks and use air pressure to dump the old liquid... pretty neat, i should have taken a picture of it. The fluid change took about 5 minutes to complete.

Don't think I've ever been at a shop for ONLY a few minutes...this is definitely a good case of, "you get what you pay for" !!! :dance:

I agree, i didnt pay for it either... free of charge, I also tried to install my eibachs but gave up cause i think i didnt have enough tools so i repaired my Pops boss' laptop and hes paying me back by installing the eibachs for me tomorrow. Win Win for me,

Not to hijack, but Griot's Garage makes a home version extractor pump, and it's under a hundred bucks.

I wonder if it works the same way this one does... This one has a plug that makes a seal around the coolant cap... it doesnt actually touch the coolant fluid, then it creates a large vaccum that causes all the fluid to shoot up and get sucked out. Then it holds that vaccum pressure and the technition pulls a lever to switch over to the tank containing the new coolant and then switches another lever that makes it to release vaccum pressure which pulls the fluid out of the large tank and back into the car.

Alittle FYI, i called the Porsche Department Service tech and asked how many liters of coolant does a My97 Boxster hold and they said 2 gallons... they didnt know in liters but 2 gallons = 7.57 liters which is just about how much that device removed from my cooling system.

Thats great! I still cannot grasp how 50+psi of vaccum can "pull" fluid all the way from radiators without opening any breather valves or anything. It goggles my mind cause i do not understand the physics behind it.

I recommend that you do it again and use the correct coolant this time.
