I don't have a coolant vacuum fill tool, so debating on having a shop take care of it if it's in need of a full flush.

I'm definitely investing in a vac fill tool and tempted to give the two items you linked a shot, although I feel like I should just commit to the schwaben unit.

But a cheap fill tool can cost only $30 or so for tool that does work and its quality is ok but not as good a tool as the forum recommend UView Airlift.

I've got the expensive UView Airlift, and a few other vac fill tools.

I apologize in advance for a possibly stupid question, but I discovered some early damage on this coolant line (water pump/t stat) and was wondering if i need to do a full coolant drain and fill when replacing it, or if i could just get away with trying to top off whatever I lose while replacing the hoses?

Yes after 5 years good idea to flush system & very good idea to Change water pump(especially if you don't know when it was last replaced), the recommendation is to change out pump every 5-6 years as regular maintenance.

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.

Current coolant has been in there for 5 years/12k miles
Not a stupid question.
Yes after 5 years good idea to flush system & very good idea to Change water pump(especially if you don't know when it was last replaced), the recommendation is to change out pump every 5-6 years as regular maintenance. Pump is a failure prone item that can cause huge problem$. And install low temp t-stat.
To change that commonly bad hose you have with the cracked plastic old brittle fragile connector you will lose lots of coolant anyhow.
With all the coolant out is as good a time as any to change out the WP, no.?
A flush can be done without a vac fill tool but its tedious to refill, sometimes takes many heat cool cycles to get all the air out and a full system. And sometimes not so bad.
But a cheap fill tool can cost only $30 or so for tool that does work and its quality is ok but not as good a tool as the forum recommend UView Airlift.
I've got the expensive UView Airlift, and a few other vac fill tools. To tell the truth, for a occasional use DIY'r, the expensive tools are nice if you don't mind spending the cash but a less expensive works just fine also.
This is one I got just to try it, and it works fine. Actually it works very well. The vac cap is not a screw on fit, it uses vacuum to hold it in and that works. I did get a cap with quick connector fitting to do pressure testing, it also can be used for this vac fill tool when filling. Or spring $175(iirr) for the UView Airlift tool...

A $26 version from Allcool! Wow. Here is the one I have :
Porsche Schwaben Cooling System Coolant Air Purge/Refill Tool. Used to refill the cooling system without air pocket issues PEL 003466SCH01 PEL.003466SCH01 PEL003466SCH01 | Pelican Parts
It's $86.
But in either case, this is a hugely useful tool to have. Here's why. You won't use this just once. First, the M96 engine has too many radiator hoses meaning the chance that one breaks on you is greatly increased. Second, the M96 engine isn't really tolerant of gaps where there is air where there should be coolant. The only way to ensure all the air is out is to do it with a vacuum assist.
If your going after that hose...I suspect the rest of them in the engine compartment will be of similar age & condition. Might be best to invest in the tooling vs. paying someone to change them. I changed all mine out at the same time along with a water pump, t-stat, & upgraded coolant connector piece that has a habit of snapping off and leaving you stranded:

I appreciate the info, thank you. I'm definitely investing in a vac fill tool and tempted to give the two items you linked a shot, although I feel like I should just commit to the schwaben unit.
Coolant and water pump and t-stat were all last replaced in 2023 when the engine was rebuilt (been about 12k miles since), so I'd like to think I still have some life on the pump and t-stat. But I'll obviously do the coolant flush.
So i got my parts but haven't picked up coolant. I've read mixed thoughts on recommended coolant between OEM Porsche stuff and Zerex g40. Any thoughts?
