Engine temperarture pass 180 F problem solved

[j.fro]

I use the app Dash Command pretty often to see what's going on with water temps and a few other things. For both my 986 and 996, the line at 180 is 180 degrees; straight up is around 200, and the right edge of the "0" is 220. I'll get the right edge/220 on a hot day in traffic, and as soon as I'm moving 35+ for a bit, the temp drops back down to 190-200.
Both cars have the 160 T-stat, new water pumps, and the larger water/oil cooler. 986 has a center radiator, 996 does not.

thanks a lot for these details they really help paint the picture and put my mind at ease as i'm getting the same temperatures (and sounds like your setup is even better than mine for the 986, i'm all stock with no center radiator) so its not out of the ordinary. i was about to drop quite a bit of money into it to try and sort it but i think i'll let it be until the next coolant change when i will upgrade to a better water pump.

still thinking about upgrading to a bigger oil cooler as that is a cheap easy improvement.

Which OBD BT are you using for the Boxster?

[j.fro]

ELM 327. I got it on Amazon under $30. Wifi, not BT.

I use this one ELM327 OBD II Wifi CAR Wireless Scanner Tool Diagnostic FOR Iphone Ipad Android | eBay

I use it with an iPad App 'DashCommand' It works well, and my temp readings are pretty much the same as others' here. Just had the WaterPump changed and the cooling system flushed amongst other things.
Driving around winding and hilly country the other day in some heavy traffic I guess the temp reached maybe 220F around 100C. Going up hills behind slow cars is murder as couldn't really get it out of 3rd in a TIP.

These 986s seem to have this heating issue, but reading through this I may just change Air Temperature Sensor for Intake Manifold. Pretty sure the fans kick in, but still I'll change the sensor just to see if it makes any difference. At the moment no CEL lights come on, so I don't know if any real issue exists.

thanks for the info! i got the same OBD II device now and using it with DashCommand its pretty cool and useful!

i went ahead and changed the engine bay temp sensor but didnt do anything. did quite a bit of research and it sounds like the only thing that will really help is an upgraded water pump from the 987 and a bigger oil cooler.
