How often should the spark plugs of Volkswagen Tharu be replaced?
3 Answers
Volkswagen Tharu spark plugs should be replaced every 20,000 kilometers. The replacement method is as follows: 1. Prepare a complete set of disassembly tools, and remove the intake pipe and antifreeze storage tank; 2. After removal, pull out the ignition coil, and use a socket and wrench tools to remove the spark plug; 3. Compare the old and new spark plugs. When installing the new spark plug, slide it slowly along the inner wall to avoid affecting the ignition gap. The function of the spark plug is to discharge the pulse high voltage sent by the high voltage wire, break down the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixed gas in the cylinder. The Volkswagen Tharu has a length, width, and height of 4453mm, 1841mm, and 1632mm respectively, with a wheelbase of 2680mm, a top speed of 200 kilometers per hour, and is equipped with a 7-speed dual-clutch transmission.
As a Volkswagen Tharu owner for five years, I've learned that spark plugs should be replaced every 40,000 to 50,000 kilometers. The manual suggests 30,000 to 60,000 kilometers, but in my experience, frequent stop-and-go city driving with traffic lights accelerates spark plug wear, making replacement necessary by 40,000 kilometers. Failing to replace them promptly caused my car to vibrate noticeably at idle and fuel consumption to spike—something I deeply regret. Now, during routine maintenance, I always have the technician check the electrode color; if it turns black, I replace them immediately. Changing spark plugs only costs a few hundred yuan, and the fuel savings make it well worth it. If the road conditions are rough, replacing them a bit earlier is even better, as it extends engine life, ensures smoother driving, and provides safety and peace of mind.
I've been driving for decades, and spark plugs are something you can't be careless about. For the Volkswagen Tharu, they generally need to be replaced every 40,000 to 60,000 kilometers. If the road conditions are bad or there's a lot of dust, you should shorten the interval. If you don't replace them for a long time, the ignition will be uneven, and the engine will shake like an earthquake. The cost of towing and repairs will be even more expensive. During maintenance, pull them out to check—if the gap is too large, it's time to replace them. I recommend changing them around 50,000 kilometers for the safest bet—don't try to save a little money. Using low-quality fuel also damages spark plugs, so choose reputable gas stations. After replacement, the car will noticeably run smoother, making long trips worry-free.
