Thanks from me too Ahsai!
I was replacing my water pump / thermostat and found orange (not pink Porsche) coolant. I'd bought Porsche coolant to replace it but needed to flush the old stuff thoroughly to avoid even the possibility of a mix reaction. This and the airlift tool made it easy. :-)

Good to know it helped and thanks for post! Must feel good knowing you got fresh coolant protecting the engine.

Great thread Ahsai.Thank you for sharing all the tech details with us.
I was apprehensive about using the compressed air to do the final flush that Ahsai did.I did not trust the pressure regulator down to 10psi on my old monster compressor. Instead I used a big shop vac (blow end ,not suck!) and that worked well.Just don't make a sealed connection between the shop vac hose and the coolant hose. You only need a high volume/low pressure air supply.It made a big mess on the floor!

Ahsai

Glad it worked out for you too! Yeah, really no need for much pressure.

Old Post, but thanks your instructions made this a cakewalk!!!!!
And now on to the motor mounts.

Ahsai

Glad to hear! I've use this method many times now and it always works great.

Another thank you here! I will be doing this as part of a water pump replacement sometime next week. I ordered the Uview and it should be here this week.

Does the 10mm deep socket and universal have to be 1/4", or can they be 3/8"? I have all parts and tools needed but just noticed these to items are 3/8" and not 1/4". My guess is "no."

You can give it a try but the I think the 3/8" are too big to get in there and maneuver.

So you’re saying my tool may be to big. That’s what she said.��

The thread that keeps on giving. I decided to purge the entire system before replacing the water pump, thermostat and some coolant hoses as the PO had the coolant replaced a week before he sold it to me and I'm pretty sure the shop didn't use oem coolant. I've heard they don't mix well, so wanted to thoroughly flush the system. Nothing like this thread and about 20 gallons of purified water to do the trick. Thanks a ton for this info -- and the airlift system idea. Had never heard of it, but won't do another coolant flush without one.

The only drama i ran into was installing the thermostat prior to remounting the hard coolant line on the same side. Just required me to disconnect the hard line at the other end that's on the opposite side of the car to route the line back in between the t-stat housing and the engine block and then reconnect both ends. Oh and those damn oem hose clamps. I'm sure they're great when new, but even with the hose clamp tool i bought, those clamps suck once old. Top thip: anyone replacing hoses should definitely replace those too. I didn't feel like waiting another week to order more, so just used worm gear clamps in the two spots where the oem clamps had lost their functionality.

Ahsai, I went to use the refill method for the first time on Blue Chips car after getting the FSI installed. I couldn't pull a vacuum over -20 cmhg and then it would immediately leak out. So I filled it manually and brought the car up to temp. Instead of filling it the rest of the way up after the thermostat opening, I put the vacuum back on. This time I pulled it up to -45cmhg without issue. I closed the valve and it still leaked back out over probably a 30s period. Should I be concerned at this point? Should I get a pressure tester and check it out in your opinion or is this minimal enough to move on?

Ahsai

Are you sure you have a good seal between the vacuum tool and the neck of the reservoir? The 30s 'leak out" maybe due to internal air pockets being extracted slowly?

Slakker

I'm not 100% sure the first time as it was my first time to use the tool. Air pockets would make sense on the 30s leakout.
