2 Answers
Chery Tiggo 8 spark plug removal method is: 1. Open the engine hood of the Chery Tiggo 8 when the engine is cold, and locate the position of the spark plugs; 2. Remove the engine decorative panel and the fixing screws on the ignition coils; 3. Disconnect the connectors on the ignition coils and pull out all the ignition coils; 4. Use a special spark plug removal tool to remove all the spark plugs from the cylinder head; 5. Install the new spark plugs into the cylinder head and tighten them to the specified torque. Taking the 2020 Chery Tiggo 8 as an example, it is a mid-size SUV with body dimensions of: length 4700mm, width 1860mm, height 1746mm, wheelbase of 2710mm, and a curb weight of 1509kg.
To remove the spark plugs of a Tiggo 8, I usually start with basic tools: prepare a spark plug socket wrench, an extension bar, and a torque wrench—remember to let the engine cool down for at least 20 minutes beforehand, otherwise it'll be too hot to handle. First, locate the ignition coils under the hood; the Tiggo 8's coils are connected to the spark plug wires, which can be gently pulled upward—no need for excessive force to avoid breaking the wires. Then, use the socket to slowly unscrew the spark plug counterclockwise, being careful not to crack the ceramic inside. There might be oil residue in the spark plug wells, so it's a good idea to blow them clean with compressed air before proceeding. When installing the new ones, tighten them to the manual's specified torque, usually around 25 N·m—too loose or too tight can affect ignition. The whole process takes about 30 minutes, and doing it yourself can save a lot of money while allowing you to check the spark plug gap. An incorrect gap can easily trigger a fault light, which is a handy maintenance tip.
