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

For several years it seemed like I would not be able to solve my overheating problem. I went through the usual suspects (new thermostat, fan clutch, hoses..etc) still had the problem.
Sometimes it would overheat and other times it wouldn't under the same conditions.
It turned out the new fan clutch I had installed went bad. Since it was a new one, I didn't think to check it. Apparently, it was engaging sometimes but eventually failed completely. I found a heavy duty aftermarket unit and haven't had a heating problem since.
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.
