Shop Chevrolet Trailblazer Replacement Ignition Coil

Sometimes, off-road travel can be needed, and if this is true for you a Chevrolet Trailblazer is the only way to go. World-class engine power and performance are supported by first-rate parts and accessories. People who want the most from their cars realize that only the best quality replacement parts should be installed. A Chevrolet Trailblazer Ignition Coil, also called an autotransformer, is an element of the ignition system which serves to transform battery voltage to more potent levels. Your vehicle's Ignition Coil amplifies the battery's 12 volts to a higher voltage, which is necessary in order to turn over the motor's cylinders. A vehicle's Ignition Coil can have an interior or exterior resistor which creates an equal voltage across the terminals instead of a sharp shock to the coil. An Ignition Coil takes the 12-volt charge from the car's battery and transforms it to an amplified voltage so that the plugs can spark, or jump, across the spark plug gap. You'll find many kinds of Ignition Coil available; the proper alternative is determined by the nature of your vehicle's electrical system.

Research on Ignition Coil for Chevrolet Trailblazer

Your Chevrolet Trailblazer Ignition Coils are an electronic engine management component that is part of your vehicle's ignition system. Your Chevrolet Trailblazer Ignition Coil functions as an induction coil that converts your vehicle's 12 volts into several thousand that are required to jump the spark plug gap and ignite the engine's air fuel mixture. Some of the ignition's systems will use one coil to be able to provide the spark that is needed for all the cylinders. However, most modern designs will use an individual coil for each cylinder. Since your Chevrolet Trailblazer Ignition Coil is the component that is responsible for generating the engine spark, any problems with it can lead to engine performance issues. Usually, a faulty Chevrolet Trailblazer Ignition Coil will produce a few symptoms that will alert the driver of a potential issue.

Signs your Chevrolet Trailblazer Ignition Coil is faulty

One of the first and most common symptoms that is normally associated with a faulty Chevrolet Trailblazer Ignition Coil is engine performance issues. As your Chevrolet Trailblazer Ignition Coil is usually among the ignition's system most vital components, any issues with it can cause a spark to be compromised; this will lead to performance issues. Faulty coils may also cause your vehicle to experience misfires, rough idle, and performance issues that will result in the vehicle stalling. Another symptom of a potential issue with your vehicle's Chevrolet Trailblazer Ignition Coil is an illuminated check engine light. When you have faulty Chevrolet Trailblazer Ignition Coil, it could lead to engine performance issues, particularly misfires, this will trip the computer to set off the check engine light. Your check engine light will also be triggered in case the computer detects an issue with the ignition coil signal or circuit. When you have a faulty ignition coil, it could lead to a no start condition. For a vehicle that uses a single ignition coil as the source of spark for all the cylinders, a faulty coil will normally affect the operation of the entire engine. In case the coil completely fails, then it will leave the engine without a spark, this will result into a no spark no start situation. Problems with ignition coils are usually easy to detect since they produce symptoms that are noticeable to the driver. In case you suspect that your vehicle's ignition coils are having an issue, then you will need to have your vehicle inspected by a professional; technician.

Chevrolet Trailblazer Ignition Coil Cost

The average cost of a Chevrolet Trailblazer Ignition Coil replacement is normally between $165 and $195.
