Suggestion
Step one is draining the coolant...and he points to the two large hose returns and says "disconnect the two large hoses..." Well, I'm very new at this and after pulling the snap connectors and looking to separate the metal pipe from the rubber hoses...I have the feeling I'm just digging myself in deep on something that isn't probably critical to adding the center radiator.
Leading evidence: 'most fun i've had working' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'most fun i've had working' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Disconnect two large hoses..." well, i'm very new at this' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

In fact, I only used a rubber flap on my air hose outlet and used my hand to press the rubber flap against the reservoir neck.

The time comes from drawing a vacuum on the cooling system and then filling the system air pocket free.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

A couple hours I'd guess on the coolant question. The coolant drains out pretty quick. The time comes from drawing a vacuum on the cooling system and then filling the system air pocket free.
Still, I'd guess a couple of hours. But you'll have to call around.
Brake flush about the same, save the brake system doesn't get a vacuum but gets connected to a power bleeder that forces in fresh brake fluid while the tech walks around the car bleeding each brake caliper in turn.
Sincerely,
Macster.
OK, I have Wayne's book on 101 projects and am looking to put in a center radiator. Step one is draining the coolant...and he points to the two large hose returns and says "disconnect the two large hoses..." Well, I'm very new at this and after pulling the snap connectors and looking to separate the metal pipe from the rubber hoses...I have the feeling I'm just digging myself in deep on something that isn't probably critical to adding the center radiator.

However--any tips on separating these hoses? And is it worth the pain at the end of the day? Coolant is very new after motor rebuild recently by a shop.
A newbie...
Tom
If you have an air compressor, you can do this method instead. No need to mess with the big hoses.

Excellence recommends a coolant flush and change every 2 years using a 50/50 mix of Porsche coolant and distilled water. Seeing how you should be doing a water pump every 4 years as scheduled maintenance also.
While I subscribe to a 4 years or so coolant drain (flushing not required) and a refill with Porsche antifreeze/distilled water blend I can't subscribe to a 4 year water pump R&R with no evidence of any water pump issues. If I had followed that schedule my 02 Boxster would have by now had 3 going on 4 water pumps vs. just the one which I had replaced at 172K miles. The replacement has over 110K miles on it.
(The Turbo's water pump lasted around 115K miles and 10 years.)
FYI - My shop wants to charge me an hour labor to drain and fill or two hours to flush and fill. For brakes, an hour labor. Hourly rate is $150. Plus consumables obviously.
Ahsai--thank you for the great tips and the tool pics. Both are very helpful to us newbies. I'm going to leave the heater cores alone....it's great to have such a clear explanation and measures of each segment's coolant. Tom
I agree and how big a job is it anyway. Easy DIY work and maybe if this was done, Just maybe less coolants tanks would split for unknown reasons. My coolant tank is original but my coolant is NOT.
Yes indeed. It was the most fun I've had working on this car to date. I may have had it at 14lbs...it "GUSHED" as you said. Maybe some air in the pipes yes...which is probably why you said 10lbs, but regardless it worked great. Perfect.
Glad it worked for you. Yea, you only need a few PSI. In fact, I only used a rubber flap on my air hose outlet and used my hand to press the rubber flap against the reservoir neck. I modulated the pressure by leaving the rubber flap not completely sealed. Really no need to have the system air tight when adding air to purge the coolant.
