How to Replace Spark Plugs in Teana 2.0?
2 Answers
Teana 2.0 spark plug replacement method is as follows: First, open the engine plastic cover, locate the engine high-voltage distributor wires, and sequentially pull out the high-voltage wires. Use a spark plug socket to remove the spark plugs, taking care to prevent dust and debris from falling in. Insert the new spark plugs into the spark plug holes and tighten them with the socket. Then, reattach the high-voltage wires to the spark plug holes. The Teana has a body length, width, and height of 4901 mm, 1850 mm, and 1450 mm respectively, with a wheelbase of 2825 mm, and features front-wheel drive. In terms of suspension, the front suspension type is MacPherson strut independent suspension, and the rear suspension type is multi-link independent suspension.
I've been driving a Teana 2.0 and have changed the spark plugs myself. It's a step-by-step process. First, gather all the necessary tools: a spark plug socket, torque wrench, and new spark plugs—none can be missing. After the engine has cooled down, pop open the hood, disconnect the ignition coil connectors, and slowly unscrew the old spark plugs. Remember not to apply too much force when unscrewing to avoid damaging the cylinder head. Before installing the new spark plugs, check the gap—usually, the manufacturer's specifications will do—then align and screw them in, with a torque of about 20 Nm. Too tight, and they might break; too loose, and you risk air leaks, which is troublesome. After replacing, reconnect the coils, start the car, and listen for smooth operation. If the engine shakes noticeably, they might not be installed correctly, and you'll need to recheck. It's recommended to replace them every 40,000 km—saves money and hassle. Doing it yourself takes at most half an hour.
