This cold blast in Central Europe is just insane. I don't think my skin has ever met -16.6 F (-27 C) before. Anyway, I started the truck today, after a few days. New battery, so it fired right up. However it started emitting a pretty crazy sound from the power steering pump area. Here's the sound on video, you can hear it everytime I turn the steering wheel (don't confuse it with the sound of the tires in snow). The truck was parked with the wheels turned all the way to the right (I don't do that normally but I was not using the parking brake due to the temperatures and wanted to position the truck so that it exerts as little force as possible to the P pin in the transmission) and when I started it it immediatelly started doing this. As it got warmer it was only doing it under load and then as it fully warmed the sound went away and I was driving the whole day without problems or noises. No leaks, no warning lights on the dash. I know the correct reply probably is "go buy a new one, fast" but I just wanted to know if it's possible that it was just due to the PS fluid being too thick at -16 F ...?
