I got used to my 97 deville digital temp, its easier to monitor specially on those engines.
i read somewhere that we can go in with an OBDII reader and add a temp display message for the 2000 and later models.

any ideas guys ?

thank you

I know I can't do it with my STS. Deville may be different. Someone will chime in.......

Take a look at www.scangauge.com . I put one in the STS and it works just fine.......I watch temperature, throttle position, timing, and intake air temperature, but there are 8 other gauges available also.

Can't do it to the best of my knowledge.
