Ive done all the cooling mods, including oil cooler, low temp thermostat, and third radiator and the car still gets to 104c in heavy traffic. Runs about 97c on the highway regardless of temp. On the track, no issues, stays below 100c.

In my experience, the cars just run hot.

180 is the correct operating temp for these cars. I have every engine cooling trick and more on my Boxster and it runs at 180. On those days on track where it is 90+ degrees and 120+ track temp it hangs 180 - 195.

160 degree stat.
Third Radiator
Extra ducting to wheel well from front radiators (racing hack + down force)
997 Oil cooler
manual switches for cooling fans.
Oil cooler with 2 6" fans.

It runs 180

Thanks for response

Lot’s of good ideas here. I like the manual fan switches idea. But it seems the S oil cooler is the best bang for buck for simply keeping the engine temp down. Is it a simple bolt on proposition? Easily accessible from the top? Had an estimate of 2.5hrs labor to do install.

If someone is going to take 2.5 Hrs. to do this, they are factoring in a long nap into the process.

Normal for stop and go
Get a phone app with bluetooth ODBII sender
You can get better temp data how it relates to gauge. You also see temps the fans come on the drive speeds where temps start to go down

If your car starts to run hot, turn on the A/C...

Sounds counter productive, but it turns on the radiator cooling fan. I do that all the time when I drive in stop and go traffic. It works.

Your car is at normal operating temperature. Just drive it and enjoy it.

Bay area...low temp thermostat...needle is on the dash above "18" for 90%+ of the year or when the car is moving 20 mph or higher. Needle rises to the dash above the 0 when stuck in the commute moving less than 15 mph on days when the temp is 80 degrees or higher.
