Jeep cherokee ignition coil

Types of Jeep Cherokee Ignition Coil

There are two main types of Jeep Cherokee ignition coils that are often sourced in the market. They are as follows:

• Distribution ignition coils: Inside a distributor, these coils are found in older vehicles. The distributor is a metal wheel inside a housing that is turned by the camshaft. The wheel has metal tabs that touch the high-voltage electricity that the coil produces. When the metal touches the tabs, it makes the electricity jump to the spark plug. The distributor has one coil. The coil is connected to the distributor cap with wires. Inside the cap, the coil is connected to the metal tabs. When the coil gets a signal from the computer to fire the spark plug, it sends a high-voltage electric charge to the tabs. The tabs move the electricity to the spark plug by touching a metal rotor. The rotor spins inside the cap. The rotor has a small tip that moves near the spark plug wire. The electricity from the rotor jumps to the spark plug by touching the tip of the plug wire, firing the plug. This is how the distributor and coil work together to make the spark plugs shoot electricity to start moving the car.
• Coil-on-Plug Ignition Coils: These coils are found in modern cars. Instead of using a distributor to move the electricity from the coil to the spark plugs, each spark plug has its own coil. So, if there are four spark plugs, there are also four coils. Each coil is placed right on top of its spark plug. When the coil gets a signal from the computer to fire the spark plug, it sends a high-voltage electric charge directly to the spark plug. This makes the electricity jump from the coil to the spark plug without needing a distributor to move the electricity. For example, the ignition coil jeep grand cherokee utilizes this system for better performance.

Specification & Maintenance of Jeep Cherokee Ignition Coil

Ignition coils have different specifications that vary depending on the type and make of the vehicle. However, here are some common specifications that can be considered when purchasing ignition coils.

Ignition coils are usually grouped into kits of 6, 4, or 2, depending on the number of cylinders in an engine. The Jeep Cherokee has 4, 6, and 8-cylinder engines. The 2001 jeep cherokee coil pack will differ from the one with a 6-cylinder engine. It's important to get the right number of ignition coils for the specific engine.

The voltage rating is another important specification to consider. The ignition coil voltage is rated in kilovolts (kV). Typical stock coils have a 40-60 kV output. However, coils with higher voltage output create a more aggressive spark. This improves the combustion process and results in optimal engine power and torque. The higher voltage also improves the acceleration of the vehicle.

The spark plug terminal configuration is also an important specification to consider. It determines how the coil connects to the spark plug. The connection method should align with the vehicle's specifications to ensure that the coil and spark plug function seamlessly.

Maintaining an ignition coil pack is important for the overall health and performance of a vehicle. These are the steps to maintain an ignition coil pack.

• Regular inspections: It's important to routinely check the ignition coil for signs of wear and tear. Visual inspections can help identify cracks, rust, or other damages that might affect the performance of the ignition coil.
• Protecting the coil: The ignition coil should be protected from extreme temperatures that can cause it to overheat. Additionally, the coil should be protected from water, moisture, and other elements that can cause it to corrode. To protect the coil, it should be installed in a clean, dry, and cool location.
• Regular engine tune-ups: Tuning up the engine regularly ensures all the components of the engine, including the ignition coil, are working efficiently.
• Quality replacement: If the ignition coil is damaged or faulty, it should be replaced with a quality coil pack for 2004 jeep grand cherokee to avoid further damage to the engine.

How to Choose Jeep Cherokee ignition coils

When shopping for ignition coils, here are the factors to consider:

• Compatibility

Ensure the ignition coils are compatible with the vehicle's engine system. This is to avoid any malfunction or damage that may occur when incompatible parts are used.

• Resistance

Ignition coils with the right resistance are the most suitable. The wrong resistance can cause the engine to misfire, fail to start, or even damage the car's emissions components. It is always advisable to consider the resistance of the ignition coils before making a purchase.

• Material

It is important to focus on the materials of the ignition coils. This is because the material used to make the coil affects its durability and functionality. Ignition coils made from copper are known to deliver a strong current. This means that they are more efficient than other materials. On the other hand, ignition coils made from other materials are affordable but less efficient.

• Brand

When shopping for ignition coils, it is advisable to focus on the brand. This is because brands that have been in the market for a long time produce high-quality ignition coils that are durable and long-lasting. Therefore, it is advisable to do some research and find out which brands are reputable for producing quality coils.

• Price

Consider the price of the ignition coils. Different suppliers have different prices for the coils. It is advisable to set a budget and find coils that are within the set budget. However, it is advisable to invest in quality ignition coils that may be expensive but are more reliable in the long run.

How to diy and replace jeep cherokee ignition coil

Replacing an ignition coil on a Jeep Cherokee is a manageable DIY project. Here's how to do it:

• Prepare for the repair: Gather the right tools and materials for the job, including a wrench or ratchet set, soft brush, and compressed air. Find the ignition coil in the engine compartment, typically located on the engine block with thick rubber wires connected to it.
• Disconnect the battery: Ensure safety by disconnecting the negative terminal of the battery to prevent electric shocks. Secure the cable away from the battery.
• Remove the old ignition coil: Carefully remove the wires connected to the coil, noting their positions. Use the ratchet to remove the bolts holding the coil in place. Gently lift the coil from the engine.
• Prepare the new ignition coil: Before installing the new Jeep Grand Cherokee ignition coil, check that it is the correct one for the vehicle. Apply a small amount of dielectric grease to the tip of each wire and the mounting surface of the coil. This helps prevent moisture buildup.
• Install the new ignition coil: Carefully place the new coil in the same position as the old one. Ensure the bolt holes are aligned. Secure the coil with bolts. Reconnect the spark plug wires in the right order. They should click in place with a slight push. Ensure you are using the correct 2004 jeep grand cherokee coil pack for optimal performance.
• Reconnect the battery: Reattach the negative terminal of the battery. Tighten the connection with a wrench. Start the vehicle to ensure the new coil works.
• Inspect the work: Look at the jeep cherokee ignition coils installation to ensure it is properly done. The wires should be correctly seated, and the coil should be securely fastened.

Q and A

Q1: How long does a Jeep Cherokee ignition coil last?

A1: Unfortunately, there is no definite answer to this question. The lifespan of an ignition coil can be influenced by factors such as the type of material the ignition coil is made of and how frequently the vehicle is used. Generally, an ignition coil can last for 100,000 to 200,000 miles before it begins to show signs of wear and tear.
