I'm looking to flush the coolant out on my car.

Just need to know what Coolant I need besides the super expensive Porsche stuff. I was looking at Pentosin along with other "pink" coolant.

Now I heard it was a pretty tedious task but I need to do it anyway.

So, how can I flush out the system. Which drain plug do i open up? Will that drain the system completely?

I read you use a vacuum type. Where do I place this vacuum and how exactly is it done?

Any answers would be great as I plan on doing this during the weekend.

 

Pain in the *** job, take it to independent or Porsche...let them do the job.

If you leave any air in system, you will have problems.

 

Well I was just curious. Like I was just told I need a vacuum pump and such. Just need to know what exactly I need to do.

 

I did it myself, you need a Radkitplus made by Snap-On. Its not too hard if your mechanically inclined.

 

Pick up some Peak Lifetime in a 50/50 mix. Can be mixed with or fully replace the Porsche coolant. $9.99 at Napa and Autozone.

What exactly is the procedure. I have no problem doing it myself but just need to know how exactly. Didn't quite see a DIY for this one.

 

Ugh... considering how many times it actually needs to get replaced, maybe ill just have a shop do it.

 

Well I found the OEM Porsche Coolant they use.

$26 per gallon. I figure I only need about 3-4 gallons. Am I right to assume this as For every gallon I put in, I need one gallon of Distilled Water.

 

This is the stuff I used, or you can pay the Porsche taxed coolant. Instructions come with the Radkitplus. Drain, hook up radkitplus to filler neck, connect air line from compressor, put into vacuum, then open valve and it will fill the system w/o air.

 

It's an easy job to do but if you leave air in the system you will know all about it. Do you have compressor and the vacuum valve?

By the time you start spending money purchasing goods etc, etc, for a job that really only needs done once or twice in a lifetime it ain't really worth it!

FWIW, I heard that Audi coolant is the excat same only with different colouring.

 

How exactly do you drain this system? Like I only see the one plus on the bottom but that can't possibly drain the whole system would it?

 

Its a pain in the ***, there is like 20 feet of piping running from the front to the back of the car and to the heater core, and its not all horizontal.
The pipes go up and horse shoe over going to the radiators, so if you really want it all out you are going to have to work for it... removed pipes and undertrays etc..... just pulling the little drain plug on the block is only going to net you a very small amount of the whole capacity. I would take it somewhere to have it done... dealer or independant..... provide your own coolant if they will let you to save some dough. Porsche has a special bleed procedure unique to the turbo that is done after using a vacuum bleeder involving their computer which runs it through different rpm ranges over a certain amount of time . With the amount of time,effort and money it would be for you to take this on your self to only have to do this once or twice for the life of the vehicle.... have someone else do it for you. Why have you decided to flush it anyways?

 

As you add the new coolant you have the back of the car jacked up so the air bleeds out by it self just add coolant slowly you don't need the vacuum equipment.

Didn't notice it until someone pointed it out to me but it seems the previous owner used the wrong coolant for our cooling system.

 

Well if he is used the wrong coolant I would be very careful as this lubricates the water pump also.
