Water pump replacement
I have 2019 Cayenne base that just surpassed 100k miles. I want to do preventive maintenance. Spark plugs transmission service and serpentine belts are on my list . Does anyone believe in water pump and thermostat simply based on mileage? I’m afraid of a coolant leak leading to bad things all of a sudden.
what are the things you all would recommend to keep things going well?
thanks in advance

Also replace the battery at this age/mileage. Your car originally had a LiFePO4 battery. If it still has a Li battery, a conversion kit to AGM is available that saves cost on the battery.

After the induction parts are removed, the water pump, thermostat and shutoff valve are the same betwen the 3.0T and 2.9TT.

As chassis wrote, I changed the water pump, thermostat and coolant shutoff valve on my 2021 Cayenne S with 2.9L twin turbo in early 2021 at about 43k miles. The valve was leaking so I did the other 2 parts as preventative maintenance since it is a pain to get in there. I would call it an advanced DIY job.
I did not remove the front bumper, AC condenser, radiator and fan. One or 2 people tried the job afterwards on 3.0L single turbo and said they could not do it without pulling the bumper cover.
Since I have not done the job on a 3.0L, I should give them the benefit of the doubt. But if I had a 3.0L, I would try since my guess is that I could do it. I will say that it takes a bit of finesse and removing parts in certain orders almost like building a ship in a bottle. It took me maybe 3 hours to get in there. After that the job was pretty straight forward. Putting everything back together is not as hard as taking it apart the first time since you understand how they fit together.
Maybe pulling the bumper makes the job a lot less complicated and is easier overall. It is not as big a deal as people think on modern cars. I have not done it on my Cayenne but have pulled my M5 bumper cover.
Try to find my thread or posts on the subject as well as those from the two people who did the job on 3.0L and then decide what you want to do.
