What is the difference between engine coolant and radiator coolant?

We also get asked, what is the difference between engine coolant and radiator coolant? No difference exists between these two names, as the fluid within both are the same. In fact, the radiator cools the engine coolant after it runs through the engine.

Can I put antifreeze in my engine coolant?

If you put antifreeze by itself, you reduce the effectiveness of your engines cooling system by up to 35%, and can cause engine damage, especially in hot weather. Never use Antifreeze by itself, use the pre-prepared coolant mixtures or mix Antifreeze with coolants to avoid engine damage.

What happens if you put wrong coolant in your car?

Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket. This can lead to damage to the engine in the worst case.

Do you add coolant to radiator or reservoir?

Tip: Most overflow tanks have a way to move the coolant they contain back into the cooling system, so it is a good idea to add the radiator fluid to this overflow tank rather than directly into the radiator.

Is it OK to put straight coolant in your car?

Pure antifreeze lacks sufficient heat capacity to keep the engine cool. In fact, if you put pure antifreeze into the cooling system, the heat-transfer capabilities are lowered by 35%, and it could really damage on the engine, especially in hot weather.

Coolant vs. Antifreeze

How do I know what coolant to use in my car?

Your car's owner's manual provides a wealth of information. It will tell you what type of coolant is best to use in your vehicle. If you don't have a copy of your owner's manual, you can most likely find the information you need online.

Can I mix old and new coolant?

If it comes to mixing different brands there is no problem, when it comes to old versus new, its okay to mix old and new as long as they are of the same type.

How do I know if my car needs coolant?

The high-temperature gauge is near or in the red.

One tell-tale sign of low coolant is the high-temperature gauge on the dashboard. This gauge is designed to tell you when the engine is getting too hot. Most often, the gauge should stay near the center of the H and C symbols.

How long does coolant last in a car?

This deteriorated liquid can trigger severe harm to your engine by failing to control the temperature. Therefore, manufacturers suggest replacing the coolant periodically. It is recommended you change coolant after the first 210,000 km (140,000 miles) or 120 months, then every 30,000 km (20,000 miles) or 24 months.

How long should you let your car sit before putting antifreeze in?

It's also very important to wait until the engine is cold (at least 3 hours from the last use) as there's a high chance that pressurised water will escape from the reservoir when you go to unscrew your coolant cap. This can scald the skin so please do handle with care!

Will car run better after coolant change?

A mechanic will then finish the coolant flush by adding fresh antifreeze to your engine along with a conditioner that will keep it protected for longer. This process improves the health and protection of your vehicle, so you will likely notice an immediate boost in engine cooling and performance following this service.

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.

What happens if you don't change your radiator coolant?

Scale and rust particles will build up in the cooling system over time. If you go too long without flushing your coolant, these particles can clog passages, potentially damaging your heater core or overheating your engine.

Does coolant affect AC?

Your A/C system uses a type of refrigerant (commonly called Freon) to cool the interior of your vehicle. Having a coolant flush performed will not help your A/C stay cool, or visa versa.

How much does it cost to change coolant?

The typical coolant exchange or coolant flush cost (or, some like to say, “radiator flush cost”) is approximately $99.99, and usually includes a full diagnosis of your car's cooling system.

Can you still drive with low coolant?

Driving a car with low or no engine coolant is risky since it may cause damage to some of the secondary and even main components of the engine. In the situation that there is a lack of coolant, it's better to pull over.

Can you change coolant without flushing?

Yes, performing a coolant flush is a good idea when you replace your car's coolant. However, because engine coolant lasts so long in modern cars, it shouldn't need to be flushed until the car has hit 100,000 to 150,000 miles.

Do you have to flush coolant before adding new coolant?

To make sure the cooling system is completely clean before adding fresh coolant/antifreeze, use a chemical flush product. Add the flush product according to the instructions through the cooling system reservoir or radiator.

Do you need to drain coolant before adding new coolant?

Experts recommend draining and replacing the antifreeze in your radiator every five years or 100,000 miles, whichever comes first. This process, along with running distilled water through the radiator before adding fresh antifreeze, is collectively called "flushing" the radiator.

Can I put water instead of coolant?

While you can drive the car for a short time using water in place of the coolant, it won't effectively protect your engine. This means its essential to get the problem that caused a low coolant level fixed as soon as possible, and the radiator filled with a 50/50 ratio of coolant to water.

Does the color of coolant matter?

Antifreeze or coolant (the terms are interchangeable) is clear when it is manufactured. Dye is used to color the antifreeze for identification and marketing purposes only. So if you were used to the tried-and-true green coolant and just opened a jug full of orange fluid, don't be alarmed.

How often do you need to change coolant in a radiator?

As a general rule of thumb, you should get a coolant flush every 30,000 miles or three to five years, whichever comes first. Your car's owner's manual should also outline a more specific interval depending on the manufacturer. Other factors include type of coolant and the environment in which you typically drive.

How do I know if my radiator is clogged?

Why is my coolant level low but no leak?

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.

How often do you need to refill 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.
