Can old antifreeze cause the engine to overheat. The tester shows that it is still okay for minus 45 degrees celsius.

x2 Fan Clutch? An infrared heat gun is great at troubleshooting. The cheap ones are $25. The cheap ones will likely be off by 2 or 3 degrees. Not a big deal in this scenario. Don't forget to use the infrared heat gun to verify the brakes are not dragging.
What's a heat gun going to tell him that he doesn't already know, that is, the engine is overheating. I'll grant you, they are great for brake issues like you mentioned, but hot engines?:h
