Simple 3-step complete coolant drain (updated w/ refill procedure + water pump tips)
#46
As I remove the stock clamps I replace them with quality SS marine ones. Much easier to work with, IMHO. Theoretically, the stock clamps should be replaced each time they are removed. A little tension goes out of them every time they are expanded. In reality, I think it would take a couple of times before they start loosing their grip.
Incidentally, the new replacement clamps from Porsche now come pre-opened and all you have to do is position the clamp, pull the blue tab and voila, it clamps down perfectly. Very nice indeed!

Those can put pressure on the fitting just under the screw and over time can cause cracking. The springy hose clamps distribute pressure more evenly.

I used this method as well a few months back. Fantastic
Although with the vacuum suck method, first fill only got about 18L in obviously there were air pockets in the front. Parked it nose down on the drive waited to warm up. Halfway there with coolant cap off it started to spew. Put cap on. Was afraid it would suck reservoir dry when t-stat opens and radiators filled up but it never did....so after t-stat opened it sucked water to the front rads (i could feel the tubes in the wheel wells getting warm). Revved as instructions. Cooled down, filled five litres (now filled 23 minus some small drips from the spewing mentioned) and went for a drive. Level is perfect since then.
Iw as dreading this part of the water pump install but actually it was a piece of cake thanks to instructions on here! Many thanks.

I am confused by the different versions of Airlift at very different price levels.
I found a generic version for about 1/2 price and wonder if anyone has experience of it and could make a recommendation? It is FJC 43610. There seem to be several re-branded ones that look identical.
Airlift do have several different models and their "economy" model is comparable to the generics?
So which do Rennlisters use ? The 550500 Airlift 2
550000
550500INT
550500HD
any others??

It works flawlessly and with the adapters even on other cars I have. Don't know about the other ones though. I've read that ppl have success with the airlift plastic one (economy) as well.

Not sure about the generic ones. Any photo or link?
I would suggest going for the known working ones as the space is quite tight where the tool hooks up to the reservoir's neck. No gaurantee that a tool with diff shape will fit.

Here is a link to various AIr lift vacuum refill tools:

here is the generic:
I read elsewhere on the Forum that the version with the tapered adapter is faster & easier to use because it seals so well.Seems counter-intuitive to me.

Getting ready to tackle this job - along with a water pump & thermostat replacement, plus a radiator clean and other odds/ends.
I'm having a hard time finding a suitable "simple rubber gasket" for sealing my air hose to the coolant reservoir. I know that a rock solid seal isn't necessary since the PSI load is low...any advice on what specifically to use? Or where to find something to hack/re-purpose?
Thanks in advance!

If so, then you'd love at what I did, I took a plastic shopping bag, poked a hole in the middle for the air hose blower tip to go through, and held the plastic bag tight over the reservoir opening with my hand, then push the button on the air hose blower tip. Works great, but just make sure you have a big drainage pan underneath because the coolant WILL gush out!!

I assume you are talking about blowing out the coolant trapped in the coolant hoses?

Spruden, I just cut a circle out of a 1/8" rubber sheet and cut a hole in the middle of it to accept the air hose. Really no need to be air-tight at all. In fact, being not air-tight gives you some control on how fast you want the coolant to GUSH out
Also, a few PSI is more than enough.

Quick update - I performed this coolant drain, water pump, low-temp thermostat, and refill procedure last week.
Draining the coolant was simple. I found some gasket material to get a "good enough" seal on the expansion tank neck. Follow Ahsai's steps and you're golden here.
The waterpump/thermostat combo was a bit of a pain - but totally doable. Just be super patient - make sure you get the engine carrier structure out of the way and there's clearance to remove/install from the bottom.
Refill with the (worst titled product in the world) Uview Airlift 55000 was awesome to see. What a simple and efficient product to use. Even though the name is annoying the product is great...highly, highly recommended.
No leaks so far - will continue to monitor coolant level and top off as needed.
