How often does coolant need to 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 does coolant need to be filled?

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. You can tell which type of coolant you have by the color.

Is it normal for coolant to get low?

Q: Is it normal for the coolant level to drop? Yes, due to the extreme engine temperature, the water element within the Coolant tends to evaporate, resulting in a coolant level drop.

Is it normal to have to top off coolant?

Refilling your coolant is a normal part of car maintenance. But if you find you have to top off your coolant frequently, this could indicate your car is leaking coolant. If this is the case, you need have a specialist at Natrad inspect your cooling system.

Why do I have to keep topping up my coolant?

Your radiator cap helps control pressure within your cooling system by redirecting some of your coolant into an overflow tank. If the cap goes bad or develops issues, it can release too much coolant too quickly, leading to an overflowing reservoir and mysteriously disappearing engine coolant.

Basic Car Care

How long should engine coolant last?

Antifreeze should be replaced every 3-5 years depending on how often and how far you drive your car, its age, and the temperature of where you usually drive.

What are the signs of low coolant?

Does coolant level drop when engine is running?

The coolant level does not drop when hot, it rises. Due to its properties, car coolant expands when heated and retracts when cooled. Its primary function is to absorb the excess heat that the engine produces to prevent your motor from overheating.

Can coolant just evaporate?

No, antifreeze does not evaporate. At least, it doesn't evaporate in the same sense that water evaporates. That's because antifreeze contains several chemical properties that are unable to evaporate well.

How long after adding coolant can I drive?

Once the hood is open, there's a risk of being sprayed with hot water or steam. “Your personal safety is most important,” he says. “Waiting for at least 15 minutes allows the hood, engine and leaking coolant to cool.”

Why is my coolant low but no leaks?

If you've ruled out an internal leak, that means your engine is burning the coolant somewhere else. The most common place is the radiator cap. Radiator caps hold the pressure inside the system, but if it's not sealing properly, then some hyper pressurized coolant will escape in the form of steam.

When should I check my coolant level?

You will want to inspect your coolant level every three to six months. What does coolant look like? It can be a green, yellow, red, or blue liquid. If you see that the liquid has a brownish appearance or it is now colorless the system will need to be flushed.

Can I just add coolant to my car?

If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself). You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water. When the coolant rises to the cold fill line, replace the cap and tighten it until you feel it click. Close the hood.

Will my car tell me when I need coolant?

Dashboard warning light: When coolant/antifreeze is low, your vehicle may notify you on its dashboard. However, not all cars are equipped with this feature. Rising temperature gauge: A rising temperature gauge may be due to an increase in your engine's temperature.

How far can you drive low coolant?

If your car has a low coolant you can drive for some time. It really relies on the level of coolant. If it is low but it is above the minimum, you can drive your car for a few days. But if it is below the minimum, please do not even try to run your engine.

Is it OK to add new coolant without draining the old?

You can add the coolant without flushing out the old. However, with time, the older coolant becomes acidic. This can cause corrosion, and afterward, can cause defects in the cooling system. Its recommended by most manufacturers that you replace the coolant after every 30,000 miles.

Is it OK to mix old and new coolant?

Some people believe that they can mix the two. This is a mistake and can lead to expensive repairs. The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating.

How much does it cost to refill coolant?

The cost of a coolant or antifreeze change will depend on the type and size of your vehicle. On average you can expect to pay between $100 and $200 for a standard coolant change.

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.

Can I change coolant myself?

You can change your coolant yourself in about an hour. You'll need to invest in an air-powered refilling tool to remove air pockets from the cooling system as you fill. You'll save about $50 on your first coolant change and about $100 on each one after that.

Is coolant in the radiator?

Car coolant is located in a reservoir affixed to the radiator before it's introduced to the engine block and its components. Engine coolant is used in conjunction with a liquid cooling system.

Does the color of coolant matter?

The truth is, color is not a reliable predictor for what type of coolant you have.

What color is universal coolant?

Traditional North American “green” antifreeze, the original “universal” formula that everybody used until the introduction of today's extended-life coolants.

Can I use water instead of coolant in an emergency?

Water by itself can't do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle's engine. Plus, it doesn't absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.
