i wa gonn post that thread just now, but yes actually i did bring the car down, and ran the coolant out with a hose. i forgot to add that part

for those of you that have an air compressor...

i'm not sure about how it cost but my mechanic has this tool that you screw in place of the coolant cap and use the air compressor to pressurize the system....

after its all pressurized you open a valve and the coolant is flushed out thru an attached hose ....

filling it up was just as easy....all the air was sucked out of the system...a hose was put into the coolant and the valve opened and all the coolant was sucked right into the system...pretty cool i thought...

my mechanic sd this was the best (and easiest) way to make sure that the system was totally flushed or filled correctly.

changing the coolant
 

Cannot seem to find the instructions & pics for changing the coolant.

can someone direct me to them?

thanks

what do u mean u cant see them?

What I mean, is that there are no pics showing the instructions I'm expecting pics showing me where to find the drain plug, pisc showing how to go about getting a complete flush, may I'm reading this wrong, should there be a link?

thanks

for those of you that have an air compressor...

Good info and definitely something to think about. It shouldn't be too difficult to fab something up....

on the 1st page there are pictures, step by step. the drain plug is an allen screw, you cant miss it once you take the cover off.
go to 1st page, if you have slow connection, wait and the pics will load up

Hi,

Just remember to keep the Pressure to 13PSI or lower to avoid splitting any hoses or blowing the Waterpump gasket...

Killjoy, Jim, Killjoy! :D

Doesn't Porsche say the coolant system is maintence free and never needs flushed?

Quote from MNBoxster:

Porsche claims their coolant is Lifetime, but don't believe it. It is simply a silicate and phosphate free Glycol based coolant. This s/b changed every 5 years/150k mi. (whichever comes 1st) in order to provide maximum corrosion protection. It is the organic carboxylates which breakdown after this interval.

Instead of buying the super-expensive Porsche Coolant, Zerex Extreme Life 5/150, Texaco Extended Life, Shell Rotella® ELC Extended Life Coolant, UNI-GARD
5/150, Mercury Extended Life Coolant Anti-Freeze, all meet or exceed Porsche Coolant requirements and are much cheaper. Use of any other type coolant is not compatible with the system and can form a gel-like substance if mixed with the proper coolant which can then obstruct flow, create hotspots, etc. Hope this helps...

Hi,

That's right - Porsche does state that their Coolant is Lifetime, but they fail to define what Lifetime is, well it's 5yr./150k mi., which to them (for marketing purposes) is Lifetime. But, Porsche doesn't produce their own Coolant, they re-label someone elses, Pentosin I believe.

There is currently no available Coolant, Consumer or Industrial, anywhere, at any price, which is chemically stable for a lifetime . If there were, every Car Mag and Enthusiast Forum would be touting it and the Mfr. would make a fortune.

Also, over time, metalic oxides, in form of scale, and bits of deteriorated hose, etc. will accumulate in the system, reducing it's efficiency. It's a good idea to flush the system regardless of the stability of the Coolant to rid the system of these particulates. Hope this helps...

or say its lifetime, and make cooling ststem be very ****************ty, so when it goes bad u have t fill it up w thier allroved brand for a small fortune, that works too.

its lifetime, too bad other stuff associated with it is not

Now this whole using a hose and running water through the coolant lines,can it be done while the car is off do I have to turn the car on?

Bump,MNBoxster,John V or dj your input is needed.

If the rear of the car is on jackstands, would there be alot of left over old fluid stuck in the front radiators that wouldnt have poured out?

this is a good practice
 

I do not care what Porsche says about "lifetime cooolant". Did mine today (52K) and it looked prety dirty. Now maybe looks have nothing to do with performance, but I do not want that crap in my car.

Are any of you guys changing the washer to your coolant drain plugs while you are flushing the coolant?

yes- crush washer
 

I did because mine was a crush type washer, and I did not want to go through all that only to undue everything and go back and put a new 50-cent washer in.

Do you happen to have the part #?
