Weather has a big effect on how your car and its coolant work. Coolant is part of the car’s cooling system and helps keep the engine at the right temperature so it can run well.
When the weather changes, the coolant has to work harder. Hot summers or cooler months can put extra stress on your engine. Knowing how weather affects your coolant helps you make smart choices for car maintenance, especially in hot places like the UAE, where temperatures can be extreme.

The Role of Engine Coolant in Your Car
Engine coolant, also called antifreeze, is a special liquid that helps your car’s engine stay at the right temperature. It stops the engine from freezing in cold weather and overheating in hot weather. No matter how the weather changes outside, coolant keeps the engine working smoothly.
The coolant moves through the engine, absorbing the heat and carrying it to the radiator, where the heat is released. Modern coolants also have protective ingredients that stop rust and wear, helping the engine last longer.
In places like Sharjah, where summers are very hot and winters are mild, a good coolant is very important. It keeps your car’s engine safe, cool, and running well all year long.
Weather and Its Impact on Engine Coolant
The weather plays a big role in how your car’s engine coolant works. Different temperatures can change how well the coolant protects your engine.
Hot Weather Conditions
In very hot weather, like during summer in Sharjah, engines can easily overheat. The cooling system in your car has to work harder when it’s hot outside.
- Heat Dissipation: In summer, the engine makes a lot of heat. The coolant helps move this heat to the radiator so the engine stays safe. If the coolant is old, weak, or too low, your engine can overheat, knock, or even get damaged.
- Coolant Quality Matters: Some coolants are made for extreme heat. Good brands, like Fubex Lubricants, make coolants that work well in hot climates, keeping your engine protected.
Cold Weather Conditions
Even though Sharjah’s winters are mild, cooler weather still affects your car. The coolant helps stop the engine parts from freezing, so everything runs smoothly.
- Antifreeze Properties: Coolants have antifreeze agents that lower the liquid’s freezing point. This means the coolant won’t freeze even if the weather gets cold. It’s helpful for drivers who travel to colder areas.
- Cold Starts: In the winter, good coolant helps your car start easily without putting extra stress on the engine.
Keeping the right coolant in your car protects your engine in every season—hot or cold.
Signs Your Coolant Needs Attention
No matter the season, it’s very important to check your car’s coolant system often. Here are some easy signs that show your coolant might need care or replacement:
- Temperature Gauge Fluctuations: If the temperature gauge on your dashboard goes too high, your coolant might be low or old.
- Leaking Coolant: If you see puddles under your car, your coolant could be leaking, and the system needs fixing.
- Discolored Coolant: Fresh coolant is usually green, yellow, or orange. If it looks brown, rusty, or dirty, it’s time to change it.
- Sweet Odor: If you smell something sweet coming from the engine, that could mean coolant is leaking.
To keep your car running smoothly, it’s recommended to get your coolant checked regularly by professionals. For the best coolant care and advice, trust Fubex Lubricants — your partner in engine protection.
How to Keep Your Coolant Working in Every Season
Your car’s coolant needs care all year to keep the engine safe. Here’s how to take good care of it:
- Regular Maintenance: Check your coolant’s level and color at least once a month, especially when the weather changes a lot. Coolant can get old and stop working well over time. It’s recommended to flush and replace your coolant every 30,000 to 50,000 kilometers, or as your car maker suggests.
- Use the Right Coolant: Always use a coolant made for your car type and the weather in your area. The right coolant keeps your engine safe in both hot and cold seasons.
- Check the Cooling System: Look at the hoses, radiator, and other parts of the cooling system from time to time. If you see leaks or cracks, get them fixed quickly.
Keeping up with these simple steps helps your car stay cool, safe, and running smoothly all year long.
Why Quality Coolant Matters
Using high-quality coolant is very important if you want your car to run well and last long. Cheap or low-quality coolants often don’t have the right additives to stop rust or handle extreme temperatures. This can cause your engine to overheat or get damaged, which leads to costly repairs.
In the UAE’s hot climate, your car needs strong protection. That’s why it’s recommended to use premium coolant from a trusted brand like Fubex Lubricants. Our coolants are made to handle tough weather and keep your engine safe all year round.
Does Temperature Affect Engine Performance?
Yes, temperature can really affect how your engine works. Every engine is made to run within a certain temperature range. When it gets too hot, the engine can easily overheat and cause problems.
What Happens to Your Engine in Hot Weather?
- More Pressure on the Cooling System: When it’s very hot outside, your radiator and coolant have to work extra hard to keep the engine cool.
- Metal Expansion: Heat makes metal parts expand, which can cause friction, bending, or even engine failure if the oil isn’t doing its job.
- Faster Fluid Evaporation: In extreme heat, important fluids like engine oil and coolant can evaporate or break down faster, making them less effective.
Over time, too much heat can make your engine weak, cause wear and tear, and lead to serious damage. That’s why it’s important to keep your engine cool and well-maintained, especially during the hot months.
How Heat Affects Engine Oil
Engine oil plays a big role in keeping your engine safe by reducing friction and wear between moving parts. This job becomes even more important in hot weather, especially in places with high temperatures all year. That’s why using high-quality oil that can handle heat is very important.
Viscosity (Oil Thickness)
Viscosity means how thick or thin the oil is. In very hot weather, oil can become too thin, making it hard to protect engine parts. When this happens, there’s more friction, more wear, and a higher chance of overheating.
To stay protected, use oil with a high viscosity index—it stays stable even when temperatures change. Synthetic or semi-synthetic oils are best because they’re made to work well in both hot and cold weather.
Thermal Stability and Oxidation Resistance
In extreme heat, oil can break down through a process called oxidation, which creates sludge and dirt inside the engine. This can block oil flow and make the engine run hotter.
Good-quality synthetic oils are made to resist heat and oxidation. They also have special cleaning additives that keep your engine cleaner and cooler for longer.
To protect your engine in hot climates, always choose a premium heat-resistant oil from Fubex Lubricants — made to perform strong, even in extreme conditions.
Why Water Isn’t Enough for Your Engine
Some people think that water is good enough to use in the radiator, but that’s not true. While water can help transfer heat, it doesn’t have the special additives your engine needs to stay protected and work well for a long time.
Limited Temperature Range
Water can boil at 100°C and freeze at 0°C, which makes it unsafe for extreme weather. In very hot or cold conditions, it can turn to steam or ice. Coolant, on the other hand, can handle much higher and lower temperatures, keeping your engine safe in all seasons.
No Rust Protection
Using only water can cause rust and corrosion inside the engine and radiator. Over time, this can lead to clogging, leaks, and expensive repairs. Coolant has anti-rust agents that protect metal parts from damage.
Scaling and Deposits
Regular water, especially from taps or rivers, has minerals that can build up inside the radiator. This buildup, called scale, blocks the flow and makes cooling less effective. Coolant prevents these deposits from forming.
No Lubrication
Water doesn’t lubricate the moving parts in the cooling system, like the water pump. Without lubrication, these parts can wear out faster. Coolant keeps everything running smoothly and reduces damage.
That’s why using real coolant instead of just water is recommended to keep your engine healthy, clean, and cool.
