Я разкажи малко , че ми с тана интересно , защото сутринта си беше понусимо , но утре го дават най-студено.

Annual Cold-Weather Reminder on Antifreeze "Overdosing"
The arrival of cold weather brings with it plenty of customers who think they should fill their cooling systems with 100% antifreeze in order to achieve maximum freeze protection. We call it the "more-is-better syndrome. Remind your customers that every brand of quality engine coolant is blended to be mixed 50/50 with water. This mix will provide the best corrosion protection, and it will protect against freezing to -34 ° F.
In serve-weather climates, coolant concentration can be increased to 69%, which will provide freeze protection to about -90°F. In concentrations greater than 69%, freeze protection actually diminishes, though a cracked engine block is unlikely. That's because highly concentrated coolant mixes tend to turn slushy in super-cold weather, and the mixture contracts rather than expands. But the thickness of the slushy mix could stall water pump impellers, resulting in broken drive belts or worse.Two Low-Flow Service Tips.
Check The Strength
Checking the strength of the coolant to determine the concentration of antifreeze in the coolant is just as important for hot weather driving as it is for cold weather. A 50/50 mixture of ethylene glycol (EG) antifreeze and water will provide boiling protection up to about 255° with a 15 psi cap, and freezing protection down to -34° F. By comparison, a 50/50 mixture of propylene glycol (PG) antifreeze and water will provide boiling protection to 257° F and freezing protection to -26° F.
Increasing the concentration of antifreeze in the coolant will raise its boiling temperature and lower its freezing point. Even so, the maximum concentration of antifreeze should usually be limited to 65% to 70% because too much antifreeze and not enough water reduces the coolant’s ability to carry heat - which increases the risk of overheating in hot weather.
Something else to keep in mind is that EG and PG antifreezes have slightly different specific gravities (densities), so be sure you use the correct type of hydrometer, refractometer or test strip when checking the coolant.
