Step-by-Step Instructions

Follow these steps carefully

1

Confirm the misfire diagnosis

Scan the 2016-2021 Hyundai Tucson for DTCs and identify the cylinder. Inspect the spark plug, coil boot, connector, harness, injector, intake leaks, and compression before condemning the coil; swap-test only when safe and appropriate.

2

Cool the engine and prepare safely

Park the 2016-2021 Hyundai Tucson on level ground, set the parking brake, switch the ignition off, let the engine cool, and disconnect the negative battery cable if required by the service procedure. Keep clear of EV/high-voltage parts.

3

Remove covers and gain access

Remove the engine cover, intake duct, or other access pieces needed to reach the 2016-2021 Hyundai Tucson ignition coils. On V6 engines, follow the engine-specific procedure for any upper intake manifold or rear-bank access.

4

Disconnect the coil

Photograph the 2016-2021 Hyundai Tucson coil layout. Press the connector lock and unplug the suspect coil without pulling on the wires. Blow debris away from the coil and bolt before removal.

5

Remove the old coil

Remove the 2016-2021 Hyundai Tucson coil retaining bolt with the correct socket, then twist and lift the coil straight out. Inspect the boot, plug well, connector, and nearby wiring for oil, moisture, cracking, or carbon tracking.

6

Install and torque the replacement

Compare the new coil with the removed 2016-2021 Hyundai Tucson part, apply only a small amount of dielectric grease inside the boot if specified, seat it fully over the spark plug, start the bolt by hand, and tighten to the exact engine-specific torque.

7

Reconnect and verify operation

Reconnect the 2016-2021 Hyundai Tucson coil connector until it locks, reinstall all covers and intake parts, reconnect the battery if disconnected, clear codes only after recording them, start the engine, and road-test while checking for repeat misfire codes.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

  • • Replacing a coil without scanning codes and confirming the misfire follows the coil
  • • Ordering the wrong coil for the engine, bank, or cylinder
  • • Pulling on a connector wire or mixing up connectors
  • • Dropping dirt into a spark-plug well or leaving the coil boot unseated
  • • Over-torquing the small coil bolt or ignoring a damaged spark plug and wiring
