Cold Temperatures The lower the external temperature, the more coolant particles contract. Sometimes, this is enough to lower coolant levels and trigger the sensor. This is especially likely if your vehicle has been sitting outside for days without use during the winter months.
Does coolant level drop in winter?
"Coolant contracts in colder temperatures, so even if the car's coolant level has fallen only a bit below normal, it could still trigger the system's sensor," says John Ibbotson, CR's chief mechanic. Add coolant to the reservoir until the fluid reaches the "max cold" or "full cold" line.
Why do I lose coolant in winter?
Why does my car leak coolant when it's cold? 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.
Do I need to add coolant in the winter?
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. In winter, the Coolant/Antifreeze lowers the freezing point and prevents freeze up, which could Crack an Engine Block.
Can coolant get low without a leak?
Even if you don't see a leak on the ground, you could still have a tiny pin hole leak in one of the hose fittings. If the cooling system isn't perfectly airtight, some coolant may evaporate slowly over time. Sometimes you actually have a slow leak that allows coolant to seep out of the cooling system in liquid form.

How often should coolant be topped up?
You need to check your engine coolant at least twice a year before summer and winter, ideally. Although, this advice may vary between car manufacturers. Coolant should be topped up whenever the level drops below the guide marks.
How often should I put coolant in my car?
On average, most automobile manufacturers recommend a coolant flush every 30,000 miles or two years, whichever comes first.
Why is my car losing coolant but not overheating?
Chances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. The longer you wait the higher the coolant leak repair cost will be. Learn how to diagnose your antifreeze leak and learn what to do next.
How long does coolant last in a car?
HOW OFTEN SHOULD YOU FLUSH THE COOLANT? Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant.
Why do I have to keep adding coolant?
If you need to top up the coolant reservoir each time it's checked, you could have a leak. Leaks can occur throughout the cooling system, and may cause serious problems, like overheating and engine damage, if left unattended.
Where is the coolant disappearing?
There are essentially four places the coolant can fall off into – Leak outside the car. A leak inside the car. Burn through the exhaust. Combust inside the engine.
How much coolant loss is normal?
How much coolant loss is normal? Providing that the engine is running well, with no leakages or damage, you can expect a coolant loss of 0.25% every four to six months. This means a loss of two to three ounces a year is completely normal.
What level should my coolant be at when cold?
If you check your coolant level when the engine is cold, the coolant should be at or above the "minimum" or "fill" line on the transparent refill container. If you check your coolant level when the engine is hot, the coolant should be at or just below the "max" line.
What level should my coolant be at when engine is cold?
“When the engine is cool, open your hood, and locate the coolant reservoir. The coolant level should be between the F(full) and L(low) marks on the side of the coolant reservoir.”
Does coolant level drop in winter?

Should the coolant reservoir always be full?
Your coolant reservoir tank should be at least 30% full. Most reservoir tank has a min and max mark drawn on the side of the container. What is this? The most common cause of a coolant leak is a bad radiator cap, bad radiator fans, and loose radiator hose clamps.
Is coolant supposed to run out?
Coolant helps pull heat away from the engine. So, without enough coolant, the engine could overheat or seize up. Continued use of an overheated engine could lead to permanent damage, such as pistons welding to the cylinders.
How do you know if you have a coolant leak?
Clues You Have an Antifreeze Leak A sweet aroma that you notice from outside the vehicle, coming from the vehicle after you've driven it. You might be able to smell it from behind the wheel as well. Puddles under the car of lime-green, orange, pink, or blue-green after you've parked.
Can I just top off coolant?
Top off the coolant reservoir If the coolant level is low in the reservoir, you can refill it to the max fill line but do not overfill it. The coolant mixture expands when it heats up and needs the extra room. Keeping your coolant at the correct level is one of the ways to keep your radiator good working order.
How do you know if your car is burning coolant?
Engine overheating or fluctuating coolant temperatures are also indicators of coolant loss. External coolant leaks can be identified by residual coolant odor after shutting down the engine, coolant smoke or steam wafting from the engine compartment or drips, puddles and stains on the garage floor.
Is coolant the same as antifreeze?
Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it's important to know what variety is right for your car or truck.
How long after adding coolant can I drive?
How long do I run the engine after adding coolant? “Your personal safety is most important,” he says. “Waiting for at least 15 minutes allows the hood, engine and leaking coolant to cool.”

What happens if the coolant in a car gets low?
If it is leaking inside the engine, then the coolant could be getting into the engine and the oil, which can damage the engine. There are only two ways that the coolant in your car gets low. There is a leak, either in the radiator, the hoses, or the engine.
What happens to coolant in the winter?
Yet, it is just as important to watch out for the coolant in the winter. The reason lies in radiator. It holds the responsibility of keeping the temperature of the engine where it ought to be. If the temperatures outside plunges below freezing, there is the possibility of fluid in the radiator freezing.
Why is coolant disappearing from reservoir secretly?
Why Is Coolant Disappearing From Reservoir Secretively? 1 The Faulty Reservoir Cap There may be times that the reservoir radiator cap may turn out to be faulty. ... 2 Bad Head Gasket A head gasket is a component that is sandwiched between the engine block and the cylindrical head within the combustion engine. ... 3 Invisible Leakage Points
Why does my coolant level fluctuate between Min and Max?
There is a coolant overflow tank which has a min and max level indicator. Normal expansion and contraction due to the radiator volume and engine cause the level to fluctuate between min and max. As long as they are within the range. you are fine and don’t need to do anything.
