Why Is My Car Overheating After Using Blue Devil?

Blue Devil is a product designed to help you save money on gas by increasing the power of your vehicle’s engine. But it can also be used as a coolant, which means it helps keep your car running at the proper temperature.

When you’re using Blue Devil, you have to make sure that your radiator isn’t blocked and that your car’s fans are working properly. If you have trouble with your car overheating after installing Blue Devil.

Make sure there isn’t any debris in the radiator or around the fan blades that might be blocking airflow. Check to see if any of your hoses are leaking where they connect to other parts of the engine block or cooling system this could cause overheating as well.

How does Blue Devil work?

Blue Devil is a very effective heat transfer fluid that is designed to improve the efficiency of your radiator by reducing the amount of time it takes for your engine to reach operating temperature, and by decreasing the amount of heat that your engine has to produce in order to get there.

Blue Devil works by changing the way your engine coolant circulates through the radiator. The primary function of an engine’s cooling system is to prevent overheating. When you turn on your car, cold water circulates through the engine block so that it can absorb some of the heat generated by combustion.

That hot water is then sent into the radiator where it cools down further before being pumped back into the engine block. This cycle repeats itself until your car reaches its operating temperature.

How to avoid overheating issues when using blue devil?

Blue Devil is a great product, but you can’t just pour it into your engine and expect it to work. There are some things you need to know before you use Blue Devil. Make sure the engine is warm before adding Blue Devil into the cooling system. If the engine is cold, it may cause damage or even cause the system to overheat while driving.

Make sure that all air conditioning lines are disconnected before adding Blue Devil into the cooling system. Do not let any air conditioning lines run into your engine compartment because they may get clogged with Blue Devil and cause problems with airflow through your car’s cooling system.

Do not fill your radiator with more than one gallon of Blue Devil at once unless directed by a professional mechanic or service center where you purchased this product otherwise, it may cause damage or even cause the system to overheat while driving.

How to prevent it from happening again?

Blue devil is a chemical additive that can be added to engine coolant to prevent corrosion. It’s not the best for your engine, though it can cause corrosion in the radiator and hoses. And if you don’t flush out your cooling system after using it, you’ll be left with a funky smell and a clogged radiator, which means you may experience overheating symptoms.

But don’t worry we’re here to help! Here are three simple steps to preventing this problem from happening again. Make sure to flush out your cooling system after using blue devil by running distilled water through your car’s radiator until it runs clear.

If you’ve been running low on coolant lately, add more before using blue devil so that there’s enough room for any additional chemicals in the mixture. Check your radiator every month or so for signs of rust or buildup, and clean them out with an old toothbrush if necessary.

The cause of the problem

One of the most common reasons is that you didn’t fill up your coolant reservoir correctly. If you only put in half as much as it needs, or if you didn’t mix it properly with water, then your car will overheat.

Another possibility is that you have a faulty cooling fan that isn’t turning on when it should. A third possibility is that there’s a leak in your radiator hose or another part of your cooling system, which would cause your engine to run hotter than normal.

What are the risks of using blue devil?

The first thing to know is that it can lead to overheating, which can cause a host of problems in your engine. If you’ve never used blue devil before, we don’t recommend starting now. The risks are simply too great to justify the benefits of using this product.

Blue devil is meant to be used in conjunction with an antifreeze solution like Prestone or Dexcool, but if you don’t have any antifreeze on hand, then it’s probably best not to use blue devil at all it could cause unnecessary damage to your car’s engine.


It’s important to remember that blue devil can cause your car to overheat. The best way to avoid this is by not using blue devil in your car. If you have already used blue devil and have noticed this problem, please take your car in for service as soon as possible.
