How often should the spark plugs of the GS4 be replaced?
2 Answers
The spark plugs of the Trumpchi GS4 need to be replaced every 50,000 to 70,000 kilometers. This replacement interval is typically specified in the vehicle's maintenance manual as well. Below is the method for replacing the GS4 spark plugs: 1. Prepare the tools: a quick wrench, socket, and a Phillips screwdriver. 2. Unscrew the high-voltage terminal, clean the dust and oil around the high-voltage terminal, then use the socket to remove the fixing screw of the high-voltage terminal. 3. Remove the spark plug. After taking off the high-voltage terminal, use the socket to loosen the spark plug. 4. Install the spark plug. First, align the spark plug with the threaded hole using the socket, then gently screw it in by hand until about half of the thread length is engaged. Finally, tighten it with the socket.
I've been driving for over a decade and have replaced many spark plugs. The original spark plugs for the Trumpchi GS4 are made of standard nickel alloy, and the manufacturer recommends replacement at around 30,000 kilometers. If you frequently drive in congested urban areas, it's safer to replace them at 25,000 kilometers. Once, I delayed replacement by 5,000 kilometers and clearly felt reduced acceleration and increased fuel consumption. Nowadays, iridium spark plugs can last up to 60,000 kilometers, but don't opt for cheap, no-name brands to save money. During maintenance, remember to have the mechanic check the spark plug gap—excessive carbon buildup can affect ignition efficiency. Also, pay attention to whether the engine starts smoothly when cold, as this is a good way to assess the condition of your spark plugs.
