Should I install an OBD gauge
I have a 2013 Mazda 3 that has no temperature guage, just a tempurature indicator: cold (blue), normal (off), and hot (red). How important is it to have a guage?
I found you can buy a temperature guage that reads the OBD port. Is it worth buying? I've heard Scotty say it is bad to have a device plugged into the OBD port for long periods of time.

As long as the overheat dummy light illuminates when the key is in the ACC position, I wouldn’t worry about it. Also, if you use the AC all the time, you’ll notice it suddenly won’t blow cool air if an engine overheat is imminent. That’s your first cue to start getting suspicious.
I’ve driven cars without temperature gauges for decades and even had one overheat (with the red temp lamp glowing). You’ll be fine, as long as you scan the gauge cluster every few minutes or so.
