Just bought a 2015 Honda Civic and then noticed that the coolant temperature gauge is not in the instrument panel. There are only two instrument cluster panel idiot lights dedicated to coolant over or under temperature.

  • In absense of a built in temperature gauge you can use an ODB reader or an aftermarket sensor. – David Winslow Sep 20 '15 at 5:48

An OBDII display is your best bet. There are lots available similar to this. enter image description here

  • wow. uh – maybe a link would be sufficient? – David Winslow Sep 22 '15 at 15:59
