I’ve got a 1993 GT that I’ve picked up and have been going through fine tuning it as it was someone else’s project. I’ve noticed that the temp gauge runs around the 150* mark most times unless it sits and idles for 30mins in 90* weather. It has an aluminum 3 row radiator with electric contour fans that are set to run at 185* and they do kick on at about the temp by the dash gauge. I know the gauges in these cars suck but it seems to be somewhat right. I will get a temp gun and shoot it and see what it says. It’s starting to cool down here in western NY so I’d like to get some heat lol.
