Heat Insulator Buyer’s Guide
- A heat insulator is used to provide extra protection to your electrical wires or cables against excessive heat.
- Heat insulators can also prevent electrical leakage, extend the lifespan of your electrical wires or cables, and ensure that electrical components are working properly.
- When looking for an aftermarket heat insulator, you should consider its material, heat capacity, application, and its manufacturer.
- You can typically buy a heat insulator for $30.
To power the various mechanical parts of the vehicle, the engine literally creates explosions inside the engine cylinders. This combustion process alone, even with a cooling system in place, can generate so much heat that it can cause damage to different parts of your car in abnormal conditions. One component that is susceptible to heat damage is your vehicle’s electrical wires.
Sometimes, due to prolonged use, these electrical wires may get damaged by the extreme heat coming from the engine. They can melt or break from being constantly exposed to high temperatures. Luckily, you can protect them from excessive heat by using a heat insulator.
What is a heat insulator?
A heat insulator is basically an additional layer of protection for your vehicle’s electrical wires or cables. Once installed, it can prevent these important electrical components from melting or breaking due to the extreme heat that may come from the engine. A heat insulator can be easily taped or slipped on to the wires and cables or placed in certain areas of your vehicle.
Benefits of heat insulation
Prolongs the lifespan of electrical wires or cables
Electrical wires can incur damage from being exposed to heat and corrosion on a daily basis. With the help of a heat insulator, you can minimize the effects of high temperatures to your wires and cables. This will effectively prevent them from wearing out prematurely, and it can even extend their service life.
Keeps electrical components functioning properly
Once the wires and cables installed in your vehicle fail, the flow of electricity will likely be disrupted and important electrical components won’t work. Several electrical components including the spark plugs, starter motor, alternator, and all the sensors needed by the engine control unit (ECU) to gather data are vital to the engine’s operation. Without enough electrical power, for example, the spark plug won’t be able to ignite the air-fuel mixture in the engine cylinders. Since the flow of electricity is important, having a heat insulator installed to protect your electrical wires and cables is necessary.
Prevents electrical leakage
When the outer coating of your wires or cables get damaged, the electricity can jump from the wires to other conductors inside the engine. And because the engine is mostly composed of metal parts, it is very easy for the electrical current to travel from one point to another. Once this happens, the electrical component connected to the faulty wire won’t receive enough electricity to function properly. You may also get bad engine ground that can cause damage to other devices like the sensors, fuel pump, transmission cables, and more.
Things to consider when looking for an aftermarket heat insulator
The following considerations are important when looking for a heat insulator for your vehicle’s electrical wires and cables.
Heat insulator material
Protecting your electrical components from extreme heat is a tough job. That’s why you need a heat insulator that is made from durable raw materials. Aftermarket heat insulators are made from various materials including PVC, rubber, silicone, rubber-like polymers, and more. Make sure you pick the insulator that can best withstand the usual wear and tear that comes with the job.
The heat insulator that you are going to get should be able to withstand the high temperatures coming from the engine or other parts of your vehicle. You wouldn’t want to replace it after just a short period of time since it would be a waste of money. That’s the reason why it is important to consider the insulator’s heat capacity. This will inform you of how much heat the insulator can take, allowing you to determine if it meets your requirements. Aftermarket insulators have different heat capacities. Some can withstand up to 500 degrees of direct heat while others can last up to 1200 degrees of continuous heat.
There are different types of products that you can use to solve your heat insulation problems. You can get a heat insulator tape that can be easily applied by wrapping it on the electrical wire or cable in your vehicle. The adhesive allows it to be secured properly on the wires. There are also wire heat shields that you can slide onto engine compartment wire looms to protect them from high temperatures. Whatever your requirements are, there is certainly a heat insulator that will suit your needs and preferences.
Just like buying a car from a well-established automaker, you also have to purchase your aftermarket products from a reputable brand. By doing this, you are saving yourself from the headache that comes with a heat insulator made with substandard quality. In addition to that, good aftermarket brands provide assurance to their customers simply by offering products with warranties or any policy that allows them to return or replace a purchased product without shelling out more cash.
How much does a heat resistant tape cost?
An aftermarket heat insulator tape can cost you around $30. The price may vary depending on the length of the tape as well as other factors like brand and material. For other types of heat insulators, the price is usually around $50 or more. If you want to give yourself extra protection, make sure to buy a product that comes with warranty. Aftermarket brands typically back their auto parts and accessories with warranties to ensure their customers can avoid the hassle that comes with defective products.
