Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Remove Ignition Coils

Locate the ignition coils on the engine (typically on top of the engine cover).
Remove any engine cover or components obstructing access to the ignition coils.
Disconnect the electrical connectors from each ignition coil.
Unscrew the bolts securing the ignition coils using a socket set and remove the coils from their mounts.

3. Inspect and Replace Ignition Coils

Visually inspect the ignition coils for cracks or carbon tracking.
If any coils are faulty, replace them with new ones. Ensure the new coils are compatible with the Renault Clio V (2019-Present).
Install the new ignition coils by reversing the removal process and tightening the bolts to the manufacturer's specified torque (usually around 10-12 Nm).

4. Reconnect Electrical Connectors

Reconnect the electrical connectors to each ignition coil, ensuring they click into place securely.
Recheck all connections and wiring for any signs of wear or damage.

5. Reassemble and Test

Reinstall any engine covers or components removed during the process.
Reconnect the negative battery terminal.
Start the engine and perform a quick visual check for any abnormal sounds or leaks.
