killerbrooks Posted April 13, 2019 Share Posted April 13, 2019 I want to add aftermarket gauges to my car and I'm trying to find a spot on the block for the temperature gauge. I am totally a novice when it comes to this stuff but does anyone know what this plug with the square is, and will using this spot work? I took out one of the bolts like the one next to the one with the square but none of the brass fittings would fit that hole. Thanks! Quote Link to comment Share on other sites More sharing options...
imr Posted April 13, 2019 Share Posted April 13, 2019 hard for me to tell but maybe coolant. Quote Link to comment Share on other sites More sharing options...
MC1of80 Posted April 14, 2019 Share Posted April 14, 2019 Yes, that will work. It may be difficult to remove. Make sure you drain the coolant otherwise you will have a mess on your hands. Quote Link to comment Share on other sites More sharing options...
