It was 85 F today so I did some testing.
5 minutes of running:
Turned the wheel and 5 minutes later:
Turned it some more. Waited 5 minutes:
Then back to 65 and 5 minutes:
The thermometer is an industrial thermocouple hooked to a PID controller. The probe was positioned near the "sniffer" on the dash. It looks like the ACC runs about 5 deg. warm.
Not bad for a 30 year old automatic system!
I love my car! 116's are the best...
