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.
I also added a product from Royal Purple. It's called "Wetter Water". You can get it at most auto supply locations or online. As advertised it kept my engine temp at nearly 20 degrees lower than when I didn't use it. It really works... I've used it in three different vehicles.
