I use a plastic storage tub underneath the car to catch all of the coolant when it drains.

Suggestion
If you use a fiber gasket with with sealant, use a minimal amount of sealant - excess sealant can break off after it hardens and get stuck in the small coolant passages in the head.

Coverage and how to read this overview
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.

Just about the change my water pump and thermostat (using a low temp replacement).
Is the sealing ring for the coolant drain the same size as for the oil pan plug? If not, does anyone know the part number?
Thoughts on flushing with distilled water after draining the coolant?
Looks like a lot of people use something like
this
to remove the hoses from the thermostat and water pump
Any other suggestions?
Park the car on an incline, nose first, so gravity assists the draining process.
Consider replacing the motor mount at the same time. Makes the "fifth" pump bolt easier to navigate.
Flush? Nah.
Approach it like it's NOT a Porsche, and you'll be fine.
In conclusion, and because this topic has been covered a billion times... do more reading. More. I.E. Seek and ye shall find.
Wrong tool for removing the hoses, you should have one of these:
You insert one of these under the hose to work it loose. Amazon sells them and they work on any hose.
You should also get a piece of cardboard the size of the water pump, and mark and label the various bolt holes in the replacement pump. Then, as you remove each bolt, insert it into the matching hole in the cardboard, that way you will know which bolt goes in which hole. Not all the bolts are the same, and the most common DIY water pump failure we see is mixing up the bolts.
It is best to use a metal gasket that comes with a coating like the original gasket - these require no sealant. If you use a fiber gasket with with sealant, use a minimal amount of sealant - excess sealant can break off after it hardens and get stuck in the small coolant passages in the head.
For draining coolant. I typically drain it directly from the hose on the thermostat when I disconnect it. I use a plastic storage tub underneath the car to catch all of the coolant when it drains.
Many people will also replace the engine mount while they are doing the water pump. It's located in the same area and it is easier to reach all the bolts while the engine mount is removed.
True, but IIRC all of them are the same size
except
one. Just make sure to keep track which one that is. The others are interchangeable. (I'm speaking based on my experience with mine, a 2001. While I think they're all similar, it's conceivable that other 986s differ. Just keep track as you take them out.)
That's almost certainly right, I stand corrected.
I remembered there was a reasonably easy way of keeping track where the long bolt(s) went...and I believe that's what it was: ie where those sleeve extensions are. I had thought it was just one, but looks like there are two.
Good call.
