Where did you aim the gun to take the temp? What emissivity value did you set the gun to read? Before the test, where did the temp gauge needle rise to when fully heated (a pic might help)?454cid wrote: ↑10 Jan 2022, 16:30 Drove to get coffee, and warm the car up, so I could take it's temperature with an IR temp gun. The highest reading I got was 140F at the top of the housing. Air temp was only around 14F, but I'm pretty sure the thermostat is mostly stuck open. Parts have been ordered.
This IR gun reading sounds like a good, quick test for anyone. I'll do it to Geronimo. Who knows when its thermostat was last replaced. But its engine temp gauge looks good and it drive well.
