Arrizo 5 Spark Plug Replacement Tutorial?
2 Answers
Steps for replacing spark plugs in Arrizo 5: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing, check for any leaves, dust, or debris externally and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, then use the socket to tighten further. Reinstall the removed high-voltage distributor wires according to the firing order, then secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replace every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the user manual. Refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs between 60,000-80,000 km.
I've done this myself three times already. Changing the spark plugs on the Chery Arrizo 5's 1.5L engine is actually quite straightforward. You'll need to prepare a 16mm spark plug socket, a torque wrench (highly recommended, but a regular socket with an extension bar will work if you don't have one), and new spark plugs (NGK DCPR7EIX or OEM equivalent). Remember to work on a cold engine! First step - safest to remove the key and disconnect the negative battery terminal. Then locate the four corner clips of the engine cover - pull up firmly to remove it and you'll see the ignition coils. Unplug the coil connectors, use a 10mm socket to remove the mounting screws, then pull the coils straight up vertically without wobbling them sideways. The spark plugs are deep in the holes below - make sure the socket is fully inserted before slowly turning counterclockwise to loosen them. When removing the old plugs, be careful not to drop any debris into the holes. Before installing new plugs, check that the ceramic insulator isn't cracked and measure the electrode gap with a steel ruler (should be around 0.8mm). Hand-tighten the new spark plugs first, then use the torque wrench to tighten to 25 N·m (if you don't have a torque wrench, gently tighten and then turn an additional 1/4 turn). Finally, reinstall the ignition coils in reverse order. The whole process takes about half an hour, but don't rush - details make all the difference!
