Where is the Spark Plug Located in Chery Cars?
2 Answers
Chery car spark plug location: The spark plug is installed on the side or top of the engine. In early models, spark plugs were connected to the distributor via ignition cables. However, over the past decade, most passenger car engines have been updated to feature direct connection between ignition coils and spark plugs. What is a spark plug: The spark plug is a crucial component of a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber and generates sparks by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. How automotive spark plugs work: Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between electrodes reaches a certain threshold, the number of ions and electrons in the gas increases avalanche-like, causing the air to lose its insulating properties. This creates a discharge channel between the gap, resulting in a "breakdown" phenomenon. At this moment, the gas forms a luminous body known as a "spark." Accompanied by thermal expansion, a "crackling" sound occurs. This electrical spark can reach temperatures of 2000-3000°C, sufficient to ignite the air-fuel mixture in the engine's combustion chamber.
I've been driving a Chery car for several years and I'm quite familiar with the location of the spark plugs. Generally, they are located in the top area of the engine, specifically on the cylinder head. You need to first open the hood and find the ignition coils. Each coil is connected to a spark plug underneath. For Chery's Arrizo series, they are located in the central part of the front engine compartment. Once you open the cover, you'll see a row of small black or gray components—those are the ignition coils. You'll need a special tool to gently unscrew them to replace the spark plugs. I've changed them myself, but I'd like to remind everyone to disconnect the battery's negative terminal before starting to avoid electric shock. Also, be careful not to loosen the wiring connections, as this could affect the engine's startup. The exact position may vary slightly depending on the model. For example, in compact cars like the QQ, they might be located a bit further forward, but the general setup is similar. If you're unsure, you can refer to the owner's manual, which has clear diagrams, or ask a car-savvy friend for help.
