Buying Considerations

Now, you had an idea about the top 10 best coils for 5.3 Vortec. However, you might find other products in the market and want to know whether they are a good fit or not.

Thus, we will give you a brief about the buying considerations you should make before purchasing any ignition coils for 5.3 Vortec engines.

The choice depends on various elements. These include your engine type, the coils type, the installation, hardware, and the material of the coils. While you might not find a product that scores the best on all factors, you should balance these aspects together to come up with the best fit.

So, let’s dive into the buying considerations for the best coils for 5.3 Vortec engines:

Engine type

All the products mentioned above are made specifically for 5.3 Vortec engines. Yet, not all vehicles have the same 5.3 Vortec engines.

For this reason, you need to double-check the engine before purchasing. In other words, it is not enough to know that your vehicle has a 5.3 Vortec engine to buy one of the above ignition coils. You also need to check the model and manufacturing year of the car before purchasing anything.

Coil type

After you are done checking the engine type and specs, check the coil type. Basically, there are two types; round and square coils.

You don’t have the luxury of choosing which coils to use in your vehicle as each vehicle comes already with its factory coils. These are the ones you need to replace and get the exact same shape of.

Moreover, you need to check the round or square coils are the same OEM parts. This is because coils have different bolt locations and this determines if they will fit into your vehicle or not.

Installation process

Generally, the installation process is very easy and doesn’t require technical expertise. The best coils will come with easy-to-install procedures that take a few minutes. Even drivers who never installed ignition coils before should easily get the process from the manual.

Further, installing the coils yourself will save you a lot of money as you won’t pay for the mechanic to get them installed. This way, you took advantage of the reduced price of replacement coils.

Additional hardware

Some ignition coils come as a set of 8 coils only while others come with additional hardware as bolts. The latter is better of course as you get everything in the same package. You don’t need to pay extra money to get bolts or wires to completely replace the coils.

From one side, this saves you money and from the other side, it prevents getting the wrong hardware not compatible with the coils.

Another additional part that some coil packages include is the spark plug cable. Sometimes, the problem is not only in the coils but also in the spark plug cables.

In this case, you need to replace everything for the ignition system to work as before. So, if you know you are having a problem with the whole ignition system, look for products with a complete set.

Performance

Coils have many effects on the overall performance of the engine and consequently, the vehicle itself. These effects include the gas mileage, throttle response, RPM level, and others.

If the coils fail to address any of these problems, there is a defect in the quality unless you have another problem with your vehicle rather than the coils.

Also, notice that some coils specialize in increasing the voltage. Others will provide better fuel efficiency and so on. Thus, you need to check the main problem you are trying to solve and get the proper solution.

Quality

Coils are sensitive parts of your car’s engine. Thus, when investing in such a replacement, you should make sure you are getting the best quality possible.

This doesn’t mean you should pay too much to get the best qualities. There are already various products in the market that provide better quality without paying too much.

A good indication of the quality is the testing and certification performed on the product and the warranty they provide.

Warranty

The longer the warranty duration is, the better. Manufacturers who offer long-time warranties with their products are sure of the quality. Thus, they back their quality products with warranties that guarantee the customers’ rights.

Mostly, you will find ignition coils with 1 or 2-year warranties. You can also find products with 5-year warranties. So, you can balance the warranty with other factors before deciding.

Customer service

Common brands always have professional customer service to help the customers with their purchases. Also, they should be experts enough to help you solve any problems that might emerge with the ignition coils you purchased from their brand.

Thus, it is better to go for brand names that have helpful customer service. Also, choose ones who are easy to reach and willing to help if you have a problem with installing the aftermarket pieces.

You can know more about the customer service of each brand by reading the reviews of other customers.

FAQs: Best Coils for 5.3 Vortec

What are the symptoms of a failing ignition coil?

There are some common signs you can easily notice to know that your coil system needs checking. These symptoms include:

• Backfiring/ ignition problems: When you try to start the engine, it refuses to start or takes time to do so.
• Fuel economy: While the poor fuel economy is a sign of different things in the car, it can be an indication of the failure of the coil.
• Vehicle stalling: with failing coils, your vehicle will remain to stall more than usual.
• Engine light: This is the easiest sign to notice as you can see the engine light turned on with no apparent reason.

If you notice one or more of these signs, you need to check the whole ignition system immediately before other negative consequences occur.

Should I change the ignition coils?

Even if you don’t notice any of the ignition system failure symptoms, you should check the coils every now and then.

All car components have a lifespan. After that, they start to wear or tear, and their performance downgrade until they become useless. So, you always need to check every part including the coils to replace when needed.

Ignition coils, in particular, are important parts to check as they provide the engine with power to ignite. If they fail, the whole engine will eventually fail.

Can I install the ignition coils by myself?

In most cases. Coils are easy to install parts as they are direct bolt-on. This means you just need to remove the old parts and bolt the new parts on.

Even newbie drivers should be able to install the coils themselves after reading the manual. After that, installation should take minutes.

However, if you face problems with installation, you can simply visit a mechanic. As an experienced person, he should take minutes to install the coils into the vehicle.

When to change the spark plug cables?

Spark plug cables are part of the ignition system just like the coils. Basically, they are the connection between the coils and the engine.

If you have a problem with the ignition system, you may need to change everything including the coils and plugs. When you check the system and find the coils completely worn out, this means you need a replacement for the whole system.

Ideally, spark plug cables should be replaced with ignition coils. If you believe your spark plug cables are in a good state, then at least keep a replacement with you when changing the coils as you might need it at any time.

How to maintain the coils?

First of all, you need to always do a check on the whole ignition system. This check is to ensure all the parts including the coils are working properly.

Next, check the spark plugs and all the wires. These parts usually wear out with the coils and you need to replace them as a whole.

Finally, clean the ignition system all the time and don’t always overheat it. Ask the coils’ manufacturer about the lifespan of the coils and change them after the determined lifespan even if they don’t show signs of failure.

What are the functions of ignition coils?

Ignition coils have the basic function of igniting the engine. In other words, providing it with the power necessary to get the engine start.

With good quality coils, the engine supposedly gives optimum performance with no delay in ignition or throttle response.

Also, ignition coils can increase the RPM levels and the overall fuel economy of the vehicle.

As they are very important, you should never run your car or truck on failing ignition coils. The consequences of this are very bad and can damage the whole engine.
