What is an ignition coil?
The coil in a car’s ignition system plays a crucial role. It takes the low-tension current from the battery, which is at 12 volts, and transforms it into high-tension current, reaching up to 45,000 volts. This amplified current is then supplied to the engine’s spark plugs. The coil is essentially a wire wound transformer filled with an insulator. This design not only ensures efficient functioning but also provides safety and reliability.
How to Clean Ignition Coil?
Clearing up the ignition coil is essential for proper and efficient vehicle performance. As daunting as it may seem, cleaning the ignition coil might just be a minor hassle if you understand the process. With the right steps and materials, your car should be running smooth again in no time.
Tool you will need:
- 5.5mm Socket
- 7mm Socket
- CRC QD Electronic Cleaner
- CRC Di-Electric Grease
- Soft copper wire brush
- New plug wire set is recommended for best results
- Small-Head Toothbrush
- Protective Gear (Gloves, Eyewear)
To safely proceed with the task, follow the steps below:
Step 1:
- Begin by disconnecting the negative battery cable from the vehicle.
- Label and remove all plug wires from the coils. You can find the firing order below for both the 3800 and the 60° V6 engines.
Step 2:
To remove the coil pack, use the 5.5mm socket to remove both screws. Then, using the 7mm socket, unscrew the connector from the bottom of the module. Note that for 60° V6 engines, there are only 3 plugs.
Step 3:
- Start by using the Electronic Cleaner to spray the top and bottom of the coils where they connect to the wire and tabs. Use the copper brush to clean them thoroughly.
- Next, clean the connections on the module where the coils connect and the connector(s) themselves using the Electronic Cleaner.
- For the final step, clean the connector(s) from the engine harness using the Electronic Cleaner.
- Allow everything to dry completely.
- Once dry, apply the Di-Electric Grease to all connections, including the top and bottom of the coils, the module connector(s), and the plug boots.
Step 4:
- Reinstall each coil.
- Carefully plug in all connectors and wires in their original positions.
- Thoroughly clean the area, ensuring there is no excess Di-Electric Grease.

To clean oil from an ignition coil effectively, follow these steps:
Disconnect the battery: This is a crucial safety measure to prevent electrical damage or the risk of shock. Ensure the battery is disconnected before proceeding.
Remove the ignition coil: Typically located near the spark plugs in the engine bay, detach any clips or bolts securing the ignition coil.
Clean the ignition coil: Begin by wiping off excess oil using a clean, dry rag or towel. Then, apply a generous amount of degreaser or engine cleaner, ensuring thorough coverage, including hard-to-reach areas. Allow the cleaner to penetrate for a few minutes.
Scrub gently: Using a soft-bristled brush or toothbrush, scrub the ignition coil gently to eliminate any remaining oil and dirt. Avoid excessive force to prevent damage to delicate components.
Rinse and dry: Thoroughly rinse the ignition coil with water, ensuring all traces of the cleaner are removed. Next, dry the ignition coil completely using a clean rag or towel.
Reinstall the ignition coil: Once the ignition coil is clean and dry, securely reinstall it in the engine bay, ensuring all clips and bolts are firmly in place.
Note: If the ignition coil is extensively damaged or has been submerged in oil, it may need to be replaced entirely.
This revised version presents the steps in a more organized and engaging manner, making it easier to follow and understand.
First and foremost, let’s address the issue of oil on the ignition coil. It’s important to determine how the oil ended up there in the first place. Ideally, it was just an accidental spill. However, discovering oil on your coil(s) when you lift the bonnet suggests there may be an underlying engine problem that requires immediate attention. Now, setting that aside for a moment, let’s discuss a potential solution. Applying WD-40 or an equivalent product can be an effective approach. Allow it to sit for five minutes, then wipe off any excess and give it a light final spray. It’s worth noting that WD-40 won’t interfere with the average car’s ignition system, though I must mention that I don’t possess expertise in luxury or high-performance engines like Ferraris. Nevertheless, WD-40 has proven effective in treating damp engines, particularly those exposed to water during activities like creek crossings in 4WD vehicles. The key concern at this point is determining how the oil managed to reach the ignition coil in the first place.
