Just bought a 2010 Forester 2.5X Premium. It has no engine temperature gauge, just idiot lights. I would really like to get a real temperature gauge for it. Anyone have suggestions on what to get and how to install it.

Scangauge. Plugs into the OBD2-Canbus port.

The idiot light is going to tell you if it reaches an unsafe temperature. At which point you shut it down, fix the problem, change the oil, and drive on.

 

I don't see the need for a gauge and frankly it's under warantee so I wouldn't F' with it unless you want to void your warantee. For the time being just leave it alone and if something really goes south then Subaru is going to pick up the tab anyway.

 

As mentioned, the OBD-II port can supply a lot of information if you really need to know the exact temp.
