Jeep Grand Cherokee Ignition coil replacement
Why do Jeep Grand Cherokee ignition coils need to be replaced?
An ignition coil channels electricity to your spark plugs, igniting the fuel in your Jeep Grand Cherokee engine’s cylinders.
A car battery is only 12 volts but thousands of volts are required to start a petrol combustion engine. That's why the coil is so important, it turns 12 volts into the thousands of volts needed to create the spark which initiates the ignition of the air-fuel mixture for combustion.
Diesel engines rely on compression to ignite the fuel so ignition coils are generally only installed in petrol engines. so if your Jeep Grand Cherokee is a diesel it's one less part to worry about.
A coil can fire hundreds of times per minute when your petrol Jeep Grand Cherokee is running – that wear and tear could mean ignition coil replacement is necessary during the life of your car.
