What is the installation method for the Tiida ignition coil?
4 Answers
Tiida ignition coil installation method: 1. Open the ignition coil cover on top of the engine, and use a pentagonal wrench to remove the ignition coil fixing screws; 2. Disconnect the ignition coil power plug, gently pry it up with a screwdriver, and remove the ignition coil; 3. Install the new ignition coil and tighten the screws, then reconnect the power plug and cover the top panel. The Tiida engine adopts technologies such as variable timing valves and double overhead camshafts, with an all-aluminum inline four-cylinder arrangement, all of which give this car an unusual power performance. The Tiida is the hatchback version of the Yida, both models have a 1.6L displacement, with soft lines and a relatively spacious and comfortable interior.
Last month I just replaced the ignition coils on my old Tiida. The whole process mainly consisted of several steps: First, disconnect the negative terminal of the battery to avoid short circuits, then use a socket wrench to remove the bolts of the ignition coil cover plate. The four coils are fixed in parallel, just pull them out one by one. Apply some special grease on the new coil boots to prevent aging, and insert them vertically into the spark plug holes—make sure they're not crooked. Finally, tighten the bolts to 10 Nm as specified in the repair manual. Remember to start the engine after installation to check for any misfiring vibrations. The whole process took about 20 minutes, the key is to follow the sequence and avoid messing up the wiring.
My friend's Nissan Tiada had a faulty ignition coil, so I brought my tools to the parking lot to help him replace it. The key items to prepare are a 7mm socket and a new coil seal. When removing the old coil, first release the fixing clip—pulling it directly might damage the wiring harness. The new part must click into place when inserted. Setting the torque wrench to 8-10N·m is crucial to prevent air leaks that could affect combustion. After replacement, always scan for trouble codes—I once encountered a misfire alarm due to an aftermarket part mismatch. The main challenge is the tight engine bay space, requiring a magnetic pick-up tool to retrieve dropped bolts.
Five key points to remember when replacing ignition coils: 1. Operate when the engine is cold to prevent burns; 2. Disconnect the battery for safety; 3. Press the clip when removing the wiring harness plug, do not pull hard; 4. The rubber sleeve of the old coil may harden and need thorough cleaning; 5. Ensure correct installation direction. For the Tiida 1.6L model, it's recommended to test if the cold start is smooth after replacement. For those with weak DIY skills, the labor cost at an auto repair shop is about 80 yuan, and the total cost including parts is around 300 yuan. Long-term failure to replace can lead to weak vehicle acceleration and increased fuel consumption.
