How to Choose the Perfect Ignition Coil Boot for Your Car's Engine
Are you having problems with starting your car? Does it run sluggish and rough while you're on the road? Does your engine often misfire? If you answered yes to all these questions, then all these point to a faulty ignition coil boot. To prevent these symptoms from getting worse, replace the boot immediately. There are no strict types of ignition coil boots, which makes shopping for one a bit tedious. So how do you know which one is the best for your engine? Here are a couple of dos and don'ts to guide you through your auto part shopping:
- Physically examine your engine before shopping for a new ignition coil boot. Although most modern engines are already equipped with
coil-on-plug technology, some older cars aren't and may not have any use for an ignition coil boot. If your ignition coil is connected to your spark plug by a rubber seal-like part, then you have a coil-on-plug system. On the other hand, if the spark plug is connected directly to the coil through wires, then buying a new boot would be a waste of money and time. So before you go around asking which ignition coil boot is the best in the market, make sure that your car actually needs one first.
- Choose only ignition coil boots that are made of high-grade materials. Since the boot will be exposed to all kinds of harsh elements, such as electrical loads, it should be able to withstand interior and exterior pressure coming from all parts of the engine. It is best to get an ignition coil boot that is made of silicone rubber. This kind of material will provide better protection against thermal overload, and it is less like to develop cracks.
- Make sure that your preferred ignition coil boot is externally insulated. Not only will it protect the ignition coil from the outside, but it will also help you handle the part better, especially during repairs and installation.
- Don't purchase an ignition coil boot that is fitted with plastic parts. Plastic auto parts tend to be more brittle and could break during operation. So to avoid endangering your engine compartment, avoid purchasing ignition coil boots that come with plastic fasteners or clips.
- Don't settle for an ignition coil boot that doesn't come with a warranty. Warrant coverage for this particular auto part ranges from a 90-day warranty to a lifetime warranty. But aside from looking at how long the warranty is going to last, also check for other conditions and limitations. Compare warranties from different dealers to make sure you get the one that you think will give you the best value.
How to Replace an Ignition Coil Boot
Is your engine suddenly misfiring? Is your gas mileage dropping at an alarming rate? And finally, is your check engine line blinking wildly? These symptoms all point to a glitch in your ignition system. So if you've checked its coils and plugs and there's still nothing out of place, it's about time you look at the ignition coil boot. This rubber part receives the most abused in your ignition system and must be changed regularly. Follow this step-by-step guide to help you replace this part with ease.
Difficulty level: Easy to moderate
Tools you'll need:
- Ignition coil boot
- Silicone dielectric compound
Step 1: Turn off your engine and allow it to cool down for a few seconds before starting on your installation job. Once it's cooled, open the hood and disconnect your car's negative battery cable.
Step 2: To get to your ignition coil boot, there are a few parts that you need to take out. Start with removing the air duct intake and its different connections and engine wiring harness from your vehicle.
Step 3: The ignition coil boot is a small cylinder that connects your spark plug wires from ignition coil. To get access to it, you must first disconnect the ignition coil from the electrical connector. Once the ignition coil has been freed of its connections, grasp your spark plug wires to remove the ignition coil boot.
Step 4: Before installing your new ignition coil boot, make sure that you coat the boot's interior with a silicone dielectric compound. Reconnect the boot the same way it was removed.
Step 5: Refasten your ignition coil to the electrical connector. You can now also reinstall the spark plug wire to the coil.
Step 6: Reassemble all the parts that were removed to gain access to your ignition coil bolt.
Step 7: Now that you've completed the installation, reconnect the negative cable to your battery and start testing your new ignition coil boot.
