Overheating occurs in winter due to a fault that occurs in a vehicle's cooling system. Most common faults are coolant leaks or a blocked thermostat. Coolant passes through the engine's coolant passages, as it does the heat that is produced by friction and combustion, in the engine and is transferred into the coolant.

Does cold weather affect car temperature?
Cold temperatures slow down chemical reactions, which means that your car battery will become sluggish and appear to be far lower than it actually is. ... It might be cold outside, but try to avoid turning your heater on for the first 15 to 20 minutes to let your engine really get up to a comfortable temperature.
How long can a car overheat before damage?
You have around 30 to 60 seconds before you start to do serious damage, such as seized up valves or even pistons, if it reaches maximum hot.
Do car's use more coolant in the winter?
The cooling system is the part most significantly affected by cold weather. As your radiator has a lot of coolant circulating through it, the obvious effect of freezing temperatures is the partial or complete freezing of your coolant.
Can low oil cause overheating?
It's usually noticed if your coolant is low, but low oil can also cause the engine to overheat. This can occur even if your coolant level is fine. If there is too little oil in the engine, it will continue to heat up because it has no opportunity to cool.
Can I pour water on my engine to cool it down?
No, Do not pour cold or still water into a hot radiator or engine — it could cause the engine block to crack due to the sudden change in temperature. This phenomenon is known as thermal shock.
How cold is too cold to start your car?
If your car gets extremely cold, the battery could freeze. Now, the good news is that it must get extremely cold before that happens. Some experts suggest as cold as negative 76 degrees. That said, even at 32 degrees, your battery can start having problems.
Do cars run better in the cold?
Cold weather and winter driving conditions can reduce your fuel economy significantly. Fuel economy tests show that, in city driving, a conventional gasoline car's gas mileage is roughly 15% lower at 20°F than it would be at 77°F. It can drop as much as 24% for short (3- to 4-mile) trips.
At what temperature will your car not start?
Additionally, cold weather increases electrical resistance, making it harder for your battery and spark plugs to do their job. At 32°F, a car's battery loses about 35% of its strength and at 0°F it loses 60%, reports AAA's Automotive Research Center via Patch.
