Subject: coolant flush/replacement

Hello all, I have a 2001 911 (6-speed) and want to flush the coolant as
part of a project to also replace the water pump and swap in a low-temp
thermostat.

I have owned this car for a couple of years and the coolant is the greenish
variety. My understanding is these cars came with a "lifetime" coolant that
was pink.

I also understand it is bad juju to mix the two types of coolants. So I'm
assuming the original coolant was replaced at some point.

So my questions are:

1) I was wanting to go back to the Porsche-approved coolant, but don't know
if it is a no-no to switch types back again.

2) Is it possible to drain the system thoroughly enough to ensure all the
old coolant is out? (for instance by jacking the front end higher than the
back/unclaming the hoses in the vicinity of the fuel filter)

Thanks.

Hi Kent,

Most everything you need to know should be in this article:

http://www.pelicanparts.com/techarticles/Boxster_Tech/29-WATER-Flush/...

I've tend to find more DIY information on Boxster forums vs 996 forums, as
more Boxster owners are DIY types.

You may not have to buy the Porsche coolant. It is probably Pentosin brand
coolant private labeled for Porsche. Just find out what G # it is, likely
G12 or higher. FYI, the color may be different, as they change the color
when updating / superceding  the coolant #.  I try to buy most parts from
AutohausAZ.com, and the dealer only parts from Suncoast Porsche in
Sarasota. Both can save you some serious $$.

You'll need to remove the front bumper to really do the job right. It's
actually pretty easy to remove the front bumper. I just did it myself
recently to replace a faulty horn. It's also a good opportunity to clean
out all the debris that collects around the radiators and AC condensors.

Thanks very much. I actually went ahead and bought the Porsche coolant from
the dealer. If you are a PCA member you get a pretty sweet discount. It was
cheaper than buying it at Pelican and having it shipped, $103 after taxes
for 3 gallons.

I have noticed that there are lots more useful DIY pages and videos from
Boxster folks and I look at as many as possible before any job.

Thanks for the video on the bumper removal. I actually hadn't planned to do
that. I was planning to disconnect the relevant hoses and jack the front of
the car up, but I will reconsider that strategy now.

I did buy a cool tool for about $104 on amazon called an UView AirLift,
which uses your shop compressor to create a vacuum on the cooling system
then refill it. Since I am installing the low-temp thermostat I was worried
I would never be able to do the procedure in the book correctly since it
wouldn't reach the same temps (the one about revving, idling, all that).

If you are interested I would be glad to loan you the AirLift device, it is
very simple. I'm doing this job tomorrow!
