Doug I inadvertently came across your pdf of the DIY on pg. 1 of this thread and I just had to say...
That is one SERIOUSLY impressive DIY. You are a valuable part of this community.

Used this guide to do my water pump and thermostat this week.
Thanks so much for all the detail. Having the right tools on hand before they were needed was immensely helpful.
Mine looked to be the original pump and was in good condition. No breakdown on the fins or bearing/shaft play.
Still a relatively cheap job and one more bit of preventative maintenance ticked off.
Next up - rotors and brake fluid flush.

OK, i know this coolant refill topic has ben covered so many times. I've read countless threads along with the WSM, gleaning a great deal of info from them, & perhaps someone can put my mind at ease about this .
2006 997 2S, 4.0L with 3rd radiator.
. Before reinstalling my new engine I drained the remaining coolant for the radiators & heater core, & used compressed air to push out any residual coolant.
. Set air con system set to heat.
. After installing engine/cooling system, pulled 25" of vacuum on the coolant system with Airlift system. 25" of vacuum held for 30 min.
. system hold 8.45 gallons + a bit for the 3rd radiator
. premixed 10 gallons of coolant & distilled water in 2 5 gal buckets
. System only pulled in 6 gallons of mix when the vacuum hit 0 & the coolant is at the full level in the reservoir
I understand that there's some burping that will need to happen, but surely not 2 + gallons.
So I decided to start over & drained the entire system again, removing 6ish gallons. Some hitting the floor of course.
Repeating all of the steps, leaving the system at 25" for 45 min, the system pulled in 6 gallons again.
Is 6 gallons adequate before going through start-up & burping procedures?
Thank you for any input.

I used the airlift system for my refill and had no issues. However, I used my Porter Cable 6 gallon pancake air compressor for the procedure and it did not provide enough capacity. So I shut off the valve and re-ran the compressor to re-build pressure, and continued. This 6 gallon pancake compressor works fine, but not in one go. Is this the issue that you are facing?
Two more questions: How did you drain the fluid? Did you disconnect the lines from underneath the pan or just from the engine? I disconnected only from the engine and even using the compressor to blow out fluid, could not fully evacuate the system. So, how are you sure you fully evacuated the fluid? Did you measure how much came out?

Regarding use of airlift, you don't need it... you can do the old fashioned way of running your engine, getting in as much as you can, then driving and getting your RPMs up around 5-6K a few times then topping off.

2006 C2S. I recently drained my system and added a 3rd radiator. I got about 5 gallons out and spilled plenty on the floor, I doubt is was a gallon's worth though. I was replacing the water pump, thermostat and some of the rubber coolant pipes as well. 6 gallons of 50/50 distilled water and Porsche coolant went back in using the AirLift. I did run it a few times afterwards to check for leaks and burp the system so it didn't all go in at once. Only going about 30 miles. Yesterday was the first time I took it out and ran it through its paces and put about 200 miles on it. Just checked my coolant level while typing this response and I was a bit low so added the final liter bringing up to the 6 gallon total mark. When my Airlift hit zero and I took it out a few times for those initial 30 miles, I did have to add coolant, so I didn't get it all in with the Airlift. I plan to keep driving and monitoring the temp and coolant level. I still have another gallon of coolant on the shelf as I was expecting to put 8 gallons of coolant mixture back in.

First off I should have thanked all that post their DYUI experiences. this resource is invaluable.
. I have a 30 gal air compressor set at 125 psi., I believe the airlift instructions recommended at least 90 psi.
. I disconnected the hoses from pipes up front, along with every other hose to pipe connection, then blew compressed air thru the system to make sure I drained as much as possible
. When draining for the second time around, I got about 5,75 gallons out. l lost a bit on the floor
. I read your post on drain & refill (thank you), along with these that provided valuable info.

I would say the coolant refill went well, its just that i only got in 6 gallons that was concerning.
Thanks

I've not started mine yet as i have a new engine & want to make sure my experience is not a bad outlier.
