I swapped the thermostat at the same time, and that seemed to make a little more clearance to get the pump out.
Leading evidence: 'Replace thermostat at the same time' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check with him tomorrow' (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.

Use 997 version iirc as it allegedly has larger vanes

My wrench used a 997 version IIRC as it allegedly has larger vanes.

If you tell a parts guys you want to replace all the coolant hoses on a 996, he will laugh at you and say, "That's gonna take some time and quite a bit of $$$"
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.

Flat6 recommends every 3 years for a water pump change. Mine is original, so it's a little over 9 years old with about 34k miles on it coming off CPO in mid November.
How difficult is this compared to a suspension swap?
Who has done this as preventative maintenance?
James (RF5BPilot) did his as preventative maintenance, my local indy did it for him and was impressed someone thought about it before it needed to be done...people who are thinking ahead of the curve tend to less problems
would this be a DIY or have it done operation - IMO easier than a suspension swap because you only doing one...not 4
My car has the original water pump as well, 35k miles but 8 years old now...
I might be tempted by a preventive DIY as well. I don't remember seing any DIY page about this. any links to share about the process. Suspension swap is also within my skills, not sure about the water pump yet

look pretty straight forward, I just have a hard visualizing the water pump coming out of this narrow space behind the engine
I assume the water pump itself must be a very thin and flat piece of hardware.
This is a pretty easy DIY. I swapped the thermostat at the same time, and that seemed to make a little more clearance to get the pump out. It's a close fit, but it will come out without much trouble. I found it much easier to get out than the damn alternator...
Did this as a preventive maintence item 5 months ago along with the LN low temp stat, serp belt, and a few coolant hoses.
I would definately use the OEM pump.
The pump definately comes out the bottom and not through the engine lid area.
If you use the OEM metal gasket I wouldn't use sealant.
Burping the system is a bit of a pain but as it takes a while.
Be mindful that you have to cut the gasket free from the engine because the water pump and oil pump (or is it the fuel pump?) gaskets were installed as 1 unit from the factory.
My car is an 03 and had 40K on it when I did it and the bearing was making a little noise once I had it in my hands. Age and coolant kills these things.
How did you decide which hose to change ? did you had a list or you simply replace the one that looked old ? It seems fairly easy I might go ahead and tackle this job. 8 years old start to count on a pump for sure.
I just loooked at the factory diagram and picked the hoses that were at the back end of the car.
If you tell a parts guys you want to replace all the coolant hoses on a 996, he will laugh at you and say, "That's gonna take some time and quite a bit of $$$"
