So just to make sure, it's known the car suffers from heat soak. So my question is what's the generally accepted operating temperature?

It seems when I'm cruising or accelerating gently, I run about 85-90 C. When I get heavy on the gas, the car goes up to 95.

That sound about right?

Where are you getting those numbers from? An aftermarket gauge, the digital dash readout (not accurate) or the little trick to read coolant temp off the stereo? Just curious.

I dont think that my car has ever went over 85 degrees... What was the outside temperature at the time??

whats the trick?

Koru_Kinshi

Digital Dash Readout. Temperature was about 90 outside. Nowadays, I don't see it go over 90.

jturkel

what temperature readouts are you guys talking about? the running temperature can be obtained by scrolling through one of the menus. it is in degrees celsius. the other temp is the outside temperature and does not require scrolling through the menus. that readout is in fahrenheit.

i think he talking about the temp when scroll through the menus from the obo section. mine never hit 90c even with a failing intercooler pump.

Could there be a problem w/the readout? I had the car serviced recently before I went on a trip up north, and they said everything checked out properly. The car also got up and down the trip to Northern California with no issue whatsoever.

It's not acting weird, or making strange noises or anything...

Press ”ecrest” for aprox 5 sec. Then press the left ”auto-button” any number of times to see the different channels.

01 In-car temperature sensor.
02 Outside temperature sensor.
03 Heater core temp, left.
04 Heater core temp, right.
05 Evaporator temperature sensor.
06 Engine coolant temperature. (most accurate)
07 Refrigerant pressure in bar (e.g. '4' is 4 bar).
08 Refrigerant temperature.
09 Not used.
10 Heater blower control voltage (normal 08-6.0, meaning .8 to 6 volts).
11 Emissions sensor voltage (to detect atmospheric gases and recirculate interior air).
12 Sun sensor voltage (to shift airflow in car).
20 Control current for auxiliary fan (electric fan on radiator, given in milliamps or mA).
21 Engine speed (x100).
22 Road speed (km/h or mph depending on installation).
23 Battery voltage at terminal 58d (as a percentage of total voltage, e.g. 99.0 = 99%).
24 Battery voltage (e.g. 12.8 = 12.8V).
40 Climate control software version.
41 Climate control hardware version.

i think its fine, just check and make sure your radiator fan is working when idle.

I like that trick. Very interesting.

It was during the summer where the temperature was up to 85 degrees on the little screen. Now since its cold outside, it barely climbs up to 80.

I'll try this 'trick' you speak of when I get in the car.
