Yes, you can top off coolant with a different brand. However, it is best to use the same brand of coolant to avoid any compatibility issues.
- Locate the coolant reservoir under the hood of your car
- The coolant reservoir is usually a plastic bottle with markings on the side indicating how full it should be
- Carefully remove the cap from the reservoir and inspect the coolant level
- If it is below the “full” line, you will need to add more coolant
- Purchase a gallon of distilled water and a gallon of pre-mixed coolant from your local auto parts store or dealership
- Be sure to get the correct type of coolant for your car’s make and model
- Pour half of the distilled water into the empty space in the reservoir, then add all of the pre-mixed coolant
- Replace the cap on the reservoir and shake it gently to mix everything together well
- Check under your car for any leaks before starting it up again, then take it for a test drive to make sure everything is working properly
Should You Top off Coolant
If your car is low on coolant, you may be wondering if you should just top it off. After all, it’s just a little bit and it’s not like you’re going to be driving cross-country anytime soon. But is topping off coolant really a good idea?
Here’s the thing: when your car is low on coolant, there’s a good chance that there’s a leak somewhere. And if there’s a leak, that means that coolant is constantly being lost. So, even if you top off the coolant, it’s just going to leak out again and you’ll be right back where you started.
There are other potential problems with topping off coolant as well. If the level of coolant gets too high, it can actually cause engine damage. And if you keep topping offcoolant without fixing the leak, eventually you’re going to run out and then you’ll be in big trouble.
So what should you do if your car is low on coolant? The best bet is to take it to a mechanic and have them fix the leak. In the meantime, keep an eye on the level of coolant and make sure that you don’t let it get too low.

Can You Use Two Different Brands of Coolant?
Sure! As long as the coolant is compatible with your engine, you can use any brand you like. Some people prefer to stick with one brand, while others mix and match depending on what’s on sale or what they have in their garage.
There are even some who believe that using two different brands of coolant can actually help prevent engine problems.
Can I Top off Coolant With Universal Coolant?
If your car is low on coolant, you may be tempted to just top it off with water. After all, water is the major component of most coolants and it’s easy (and free) to come by. However, this is not a good idea.
Water doesn’t have the same properties as coolant and can actually damage your engine.
Most coolants are a mixture of water and glycol. Glycol is an antifreeze that helps protect your engine from overheating and freezing.
It also contains corrosion inhibitors that keep your engine clean. Water doesn’t have these properties, so it can’t adequately protect your engine.
In addition, topping off with water can throw off the ratio of water to glycol in your coolant.
This can make the coolant less effective and potentially cause problems down the road.
It’s always best to use the recommended coolant for your car. If you’re unsure what type of coolant to use, consult your owner’s manual or ask a mechanic.
Using the wrong type of coolant can also cause problems, so it’s best to avoid mixing different types together.
What Happens If You Mix Different Coolants?
If you mix coolants, the properties of each coolant will change. The boiling point and freezing point will be different, as well as the specific heat and thermal conductivity. Additionally, the corrosion inhibitors in each coolant will no longer work effectively.
It is generally not recommended to mix coolants.
Can I Top off Coolant With a Different Color?
If your coolant is low, you may be tempted to just top it off with whatever you have on hand. But is it really okay to mix different colors of coolant?
Here’s what you need to know.
Coolant, also called antifreeze, comes in many different colors including green, orange, pink, blue, and yellow. The reason for all the different colors is that each one contains a different chemical additive that helps protect your engine from corrosion.
So, can you mix coolants with different additives?
It’s not recommended. Different additives can react with each other and cause clogging or deposits in your engine. Additionally, mixing coolants can result in an uneven concentration of additives which can actually accelerate corrosion.
If you’re topping off your coolant and notice that the color doesn’t match what’s already in your radiator, it’s best to drain the system and start fresh with new coolant. That way you’ll know for sure that your engine is protected against corrosion.
CAN YOU MIX COOLANT COLORS, BRANDS OR TECHNOLOGIES??
Conclusion
Different types of coolant can be used interchangeably as long as they are the same color. It is not recommended to mix different brands of coolant together.
