Leading evidence: 'Check coolant cap part number is 03 or 04' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check coolant cap part number is 03 or 04' (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.

whoa...congrats...and the temp gauge is running a bit hot ...were you stopped and idling after rush hour?

Driving along holding a camera in front of my face using my knees to keep the car in its lane I think at that time 72mph (70mph actual, speedo reads 2mph high) is plenty fast enough.
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.

It could be the angle of the pic, but I'd be keeping a close eye on the gauge with those temps.. Do you have a third radiator or maybe looked into the fan mod? Now those conditions easily happen here in sunny South FL; except I noticed when I have the AC temp set to LO, the fans up front kick in and blow a ton of hot air off the front rads, which may keep the temp in check. Or try to find a nice open road to run the engine a bit to bring the temp down some.
check Macster's temp in the pic below...that HOT! but the temp gauge is near sweet....pry on a nice open road keeping the air flowing ...
May not be "broken". Temp gages in these cars are not the most precise indicators of temperature. When my car encountered very high ambient temperature (116F) and the temp gage climbed to that region of the dial when I returned to dealer and spoke with the service manager about the conditions: 116F ambient; 226F coolant temp (read using an OBDII scan tool); 135F air intake temperature (ditto); service manager told me factory said that as long as the coolant warning light not on or flashing on the car suffered no harm from the elevated temperature.
If you want to know what the actual coolant temperature is buy an OBDII scan tool and use it to read the coolant temperature (and intake air temperature, etc.) in real time. The gage is there for decoration.
Check the coolant cap part number is 03 or 04. If it isn't you might want to replace the cap. The older ones leak. Also, check the coolant fluid level. If low the cap is leaking or there's a leak somewhere else. Coolant tank a common source of a leak.
With a properly sealed cooling system that can hold pressure these engines can tolerate a coolant temperature of nearly 250F without any boiling. But the ability of the cooling system to maintain pressure is critical. It is the pressure that raises the boiling point of the coolant. The anti-freeze is there well to prevent freezing and for some corrosion protection.
Besides, 90F not hot. This is hot:

I've got 114k. Have fun driving it even more and being amazed at how great of a car it still is with 100k+ on the clock. Figure 20k/tire set then 5 times $1600 avg for how many dollars in tires.
Congratulations on the 100K roll.
I have 121,000 on my DD 99 996. It was Ed's (ivangene) old car and the second time I have owned this car. I just did the 120K service a month ago. I do have to spend some $ on a clutch and tensioner soon - just waiting on parts. It still has the original engine, IMS/RMS and other parts that folks seem to say are about to grenade.
I plan to keep the car for a few more years, until a 997 GT3 or 911 PDK (if proven to be reliable in the long term) gets within my depreciated target price range. But right now, even if I have to buy a new engine, I'm finding it hard to replace this car as a DD with another car with the same level of enjoyment and low depreciation cost (depreciation cost depends when and how much you bought it, of course).
Keep driving your car! I'm convinced the more you drive it, the less non-routine maintenance-related issues you'll have.
Driving along holding a camera in front of my face using my knees to keep the car in its lane I think at that time 72mph (70mph actual, speedo reads 2mph high) is plenty fast enough.
I-40 speed limit in AZ is 75mph (though in Flagstaff and Kingman limit drops to 65mph through the towns) but once one crosses the Colorado River limit drops to 65mph and the road from the CA state line to the inspection station some of the worst road around. Lots of bears too. From the CA line to at least Needles.
Once one gets outside (west) of Needles there's 140 miles of essentially open road with IIRC a limit of 70mph though for a longish section the limit is reduced to 65mph.
And there can be lots of CHP patrol cars -- passed several going the other way across there -- and once (not this time though) I even spotted a bear in the air, but I can maintain a pretty good speed average when I want to with the help of my V1 and CB radio and sharp eyes. Oh, and the Turbo helps too...
Sincerely,
Macster.
