Starting after a short rest - Toyota Corolla, 1.4L, 1998

Recently I had a rest at the dachas with friends and a girl for 3 days, I left the car in the garage, all these days it was not hot, about -15. As I arrived home, I immediately went to the garage, started the car and, by the sounds of the engine, I realized that the rest was not good for the car, the vibration went through the car, which groan was at the engine, I generally keep quiet) the alternator belt that required replacement (at the moment changed but due to weak stretching slightly whistling) whistled scary but after 15 minutes of work, everything was normal. For myself, I concluded that, on cold winter days, the car must be started every day, the battery will not sit down, the engine will not make strange and incomprehensible sounds! This is my personal observation, do not judge strictly)
