Most people know that they need to keep their car’s engine coolant level topped up, but many don’t know how much they should be putting in. In this blog post, we will provide a comprehensive guide on how much coolant your car needs and what you should do if it runs low.
Cars need 1.5 to 3 gallons of coolant, mixed in a 50:50 ratio between antifreeze and demineralized water. You can also use prediluted coolant to avoid mixing it yourself.
How a Car’s Coolant System Works
Your car’s coolant system is made up of a series of hoses and components that work together to keep your engine at the correct operating temperature. The coolant itself is a mixture of water and antifreeze, which helps to protect your engine from corrosion and overheating.
The coolant mixture circulates through your engine and absorbs heat, before being pumped back into the radiator where it is cooled by the airflow passing through it.
If there is not enough coolant in the system, or if the mixture is too diluted, then it will not be able to effectively remove heat from the engine and it can overheat.
What Should I Do When My Engine Coolant Runs Low?
Occasionally, you may notice that your engine coolant is running low. In such cases, the first thing you should do is check for leaks. If there are no leaks, topping up the coolant should be a simple process.
However, if there are leaks, you will need to repair them before adding more coolant.
It is also important to know what type of coolant your car uses. Most cars use a 50/50 mix of water and antifreeze, but some require a different ratio. Be sure to check your owner’s manual or ask a mechanic before adding coolant to your car.
Some of the types of engine coolant include:
- Ethylene glycol
- Propylene glycol
- IAT coolant
- OAT coolant
Each of these types of coolant has its own benefits and drawbacks, so be sure to do your research before deciding which is right for your car.
Ethylene glycol is used in most cars and is the most common type of engine coolant. It is effective at preventing corrosion and overheating, but it can be toxic if ingested.
Propylene glycol is a less-toxic alternative to ethylene glycol and is often used in food-grade antifreeze. It is not as effective at preventing corrosion and overheating as ethylene glycol, but it is safer for children and pets who may accidentally ingest it.

IAT coolant is made with a mixture of water and silicate. It is effective at preventing corrosion, but it can cause deposits to form on engine parts over time.
OAT coolant is made with a mixture of water and organic acids. It is effective at preventing corrosion and deposits, but it can cause corrosion in aluminum engine parts.
No matter which type of coolant you choose, be sure to check your car’s owner’s manual for the correct proportions of water and antifreeze. Adding too much or too little of either can cause problems for your car’s engine.
In case you’re ever in doubt, the best thing to do is take your car to a mechanic and have them check the coolant level for you. They will be able to top off the coolant and make sure there are no leaks in the system.
How to Top off Your Car’s Engine Coolant: A Step By Step Guide
- Step One: Find the coolant reservoir. This is usually located near the radiator, but it can be in other locations depending on your car’s make and model.
- Step Two: Check the coolant level. If it is below the minimum line, you will need to add more coolant.
- Step Three: Open the cap on the coolant reservoir and add the correct amount of coolant. Be sure to use the correct type of coolant for your car.
- Step Four: Close the cap on the coolant reservoir and start the engine. Let it run for a few minutes, then turn it off and check the coolant level again.
When everything looks good, you’re finished! Be sure to keep an eye on the coolant level and top it off as needed. And that’s everything you need to know about engine coolant.
How Do Leaks on My Car’s Cooling System Happen?
There are a few different ways that leaks can happen in your car’s cooling system. The most common way is through the radiator hoses. These hoses are made of rubber and over time, they can develop cracks and holes.
Another common way for leaks to happen is through the water pump gasket. This gasket seals the water pump to the engine block and over time, it can deteriorate and cause leaks.

When you notice any coolant leaking from your car, it’s important to have it fixed as soon as possible. Leaks can lead to overheating, which can damage your engine.
The best way to prevent leaks is to have your car’s cooling system inspected and serviced regularly. A mechanic will be able to spot any potential problems and fix them before they become serious.
What Happens When My Car Engine Runs Low on Coolant?
At some point, your car’s coolant will run low. When your car’s engine runs low on coolant, it can cause a number of problems. The most serious problem is overheating. When the coolant level gets too low, the engine can’t dissipate heat properly and it will start to overheat.
Overheating can damage various engine parts, including the cylinder head, piston rings, and bearings. It can also cause the engine to seize up, which will lead to a costly repair bill.
Another problem that can occur is corrosion. Coolant helps protect the metal parts of the engine from rust and corrosion. When there’s not enough coolant, these parts can start to corrode and break down.
Is It Okay to Drive My Car If It’s Low on Coolant?
Whenever your car is low on coolant, it’s not safe to drive it. The best thing to do is to add more coolant and have the system checked for leaks. Once you’ve done that, you should be able to continue driving without any problems.
However, if your car’s engine is already overheating, it’s best to tow it to a mechanic and have them take a look at it. Driving an overheated engine can cause serious damage and it’s not worth the risk.
What Is the Ideal Ratio of Coolant to Water?
The ideal ratio of coolant to water is 50/50. This means that you should add equal parts antifreeze and water to your car’s cooling system. However, some cars require a different ratio. Be sure to check your car’s owner’s manual to see what the manufacturer recommends.
Adding too much antifreeze can cause problems, so it’s best to stick with the 50/50 ratio unless your car requires otherwise.
How to Check Your Car Engine Coolant Level
Now that you know how important it is to keep your car’s engine coolant level topped off, you might be wondering how you can check it.
It’s actually quite simple. The first thing you need to do is find the coolant reservoir. This is usually located near the radiator, but it can be in other locations depending on your car.
Once you’ve found the reservoir, remove the cap and check the level of the coolant. If it’s low, add more until it reaches the “full” line.
It’s important to check your car’s coolant level regularly and top it off as needed. This will help keep your engine running smoothly and prevent any costly repairs.
Conclusion
In summary, it’s important to keep your car’s engine coolant level topped off. The ideal ratio of coolant to water is 50/50, but be sure to check your car’s owner’s manual to see if a different ratio is required.
If you notice any leaks, have them fixed as soon as possible. And finally, if your car overheats, tow it to a mechanic to have it checked out.
