The key test there is that the gauge is accurate. Now we can use the temp gun to isolate or read the temps in various places to get a picture for what the issue is.

Make sure not to use these guns on chrome or polished pieces -- they don't get as good of a reading on those surfaces.

Many times -- I'll just read right off the fins of a radiator... just point the gun at an angle so it gets a good look at the surface you're trying to measure. It's also helpful to read near the exhaust ports of the head... the sides of the block etc.

Trust me i was checking the temp of almost everything lol. The rad reads different all throughout, nothing more than a 20* difference.

the headers get extremely hot, upwards of 200*f +.
