The cold weather puts your car under a lot of stress. Firstly, the snow puts excessive strain on the tires. Since the tires struggle to make it through the snow, the suspension also goes through a lot of stress. Similarly, the car’s engine also bears a lot of pressure in severely cold temperatures.
However, the most damage is caused to the cooling system of a car. If the cooling system hasn’t been maintained properly, it can cause a lot of problems in the winter months. (Do you need a radiator repair or replacement? Contact us at 704-821-3460 for a free estimate.)
Let’s look at the adverse effects of cold weather on a car’s radiator:
Cracks in the Radiator
If the coolant mixture in the radiator is not of the right proportion, the liquid can freeze inside. The cooling system is quite sturdy. However, it is not built to handle ice buildup. If the water freezes inside the radiator, it puts immense strain on the radiator case. When the radiator cracks, it begins leaking water rapidly. This can cause a lot of problems if it happens while traveling over long distances.
Clogged Lines
Similar to the reservoirs in the radiator, the fluid lines can also get clogged due to the ice. The fluid lines are quite delicate and develop leaks. Even if there are no leaks immediately, the lines do weaken over time. It can cause the lines to give way under intense conditions. You may not even experience the failure all winter. However, when the radiator heats up in the summertime, the lines will give way.
Transmission Failure
In automatic transmission vehicles, the transmission cooling lines run through a compartment in the radiator. If the radiator freezes and causes a fluid leak, the transmission fluid and coolant could get mixed. If the fluid runs in the engine cooling lines, it won’t harm the engine. But the coolant in the auto transmission housing can damage the transmission. You will have to change the radiator as well as have the transmission rebuilt completely.
It is best to keep your radiator well maintained. The most important thing is to keep the coolant and water ratio accurate to avoid freezing. During the Charlotte winter months, we have seen very warm temperatures and very cold temperatures. If you are having radiator issues, contact us immediately to avoid larger radiator problems.

FAQs
The adverse effects of cold weather on a car's radiator include Cracks in the Radiator, Clogged Lines, and Transmission Failure.
Can cold weather affect your transmission? ›
Contracting Components: Icy temperatures can cause components in your vehicle's transmission to contract. Rubber parts such as seals are especially vulnerable to this type of damage, and while the damage may not be apparent at first, the wear and tear will eventually cause major issues.
Can cold weather crack a radiator? ›
Cast iron is particularly susceptible to the stress caused by freezing temperatures and are more likely to crack than less brittle materials. Cracked cast iron radiators will likely need to be replaced. The pipes in baseboard radiators can also freeze, but they may be repairable.
Does cold weather affect your coolant? ›
The reason for this precaution lies in the nature of liquids and their response to temperature changes. In cold temperatures, the coolant can contract, leading to a noticeable decrease in the reservoir's coolant level.
Why does my radiator leak when cold? ›
The cold will also likely be causing your metal radiator to contract, making it much more likely your hoses and hose clamps come loose if they're not tight enough. This is why you may find your car radiator only leaks when it's cold.
What temperature is too cold for a transmission? ›
Viscosity change: The viscosity of transmission fluid changes and gets thicker in the cold. The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick.
What temperature is bad for transmission? ›
The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees, bad things happen, starting with the formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burning out, carbon being formed, and, ultimately, failure.
How do I protect my radiator from cold weather? ›
Antifreeze, commonly referred to as engine coolant when it's a 50-50 solution, stops water in your engine's cooling system from freezing during those cold winter days and nights. It also raises the boiling point of your engine to keep it from overheating.
How cold does it have to be to freeze water in a radiator? ›
Water freezes at 32 F.
How do you treat a cold radiator? ›
Fully open all radiator thermostats and run the heating at full temperature for 10 to 15 minutes with all radiators on. Turn the circulation pump off and wait until radiators are cool (around half an hour to an hour) Bleed the radiator nearest the boiler using a bleed key or screwdriver until water comes out.
Does my Car Need Coolant In Winter? Your Car's Cooling System (Water Pump, Hoses, Radiator, Thermostat, Heater Core) needs service year-round, regardless of the weather.
What happens when coolant is too cold? ›
Frozen coolant can lead to your radiator expanding in order to make room for the frozen liquid. As the radiator expands, cracks can develop, and a slew of problems can emerge, including other liquids mixing with the coolant.
Should you start your car periodically in cold weather? ›
The idea that you need to start your car every day in cold weather to keep it running is outdated. Modern cars are well-equipped to handle cold weather, thanks to advancements in automotive technology.
Why is my radiator losing coolant but no leaks? ›
If the coolant level is dropping and there is no external leak evident, then the coolant is probably leaking internally, into the engine. If the car has recently overheated then this could have caused the head gasket to fail. If it has, it could be leaking coolant into the combustion chambers.
What is the most common cause of radiator leaks? ›
Corrosion
The leading and most common cause of radiator leaks is corrosion and rust brought on by consistent exposure to heat and pressure.
Can a radiator stop leaking on its own? ›
No. A coolant may stop leaking, but you can be sure it will be back after some time. If it's a major one, call an expert who will fix this.
Why does my transmission shift bad when its cold? ›
When the transmission gets cold it can cause parts to contract in size. Parts that have contracted fit looser than they are supposed to, which can make parts wear out faster or cause leaks due to seals shrinking. There can be a computer delay when the transmission is not at a proper temperature to function correctly.
Why is my transmission not working in the cold? ›
The real problem in cold weather is that your transmission fluid becomes thicker and doesn't flow as well. What that means is that it can't do its job as well and your transmission parts aren't as lubricated as they need to be to function well, i.e., they aren't as protected.
Does your transmission need to warm up? ›
There's no “not fully flowing” with an automatic gearbox - there's the factor of viscosity, but that is mitigated by modern transmission fluids. You don't have to wait for it to “warm up”. But, it's moving, and moving fully, from the very moment the engine turns.
How do I warm up my transmission? ›
So, when it's extremely cold outside, start the engine, and let it idle for a minute or so before putting it in gear or under load. This allows engine oil and transmission fluid to circulate and lubricate. Then shift into gear and let the engine and transmission warm another 30 to 60 seconds.
