Which way to turn the fuel tank cap?

[LeMiguel]

The direction to turn the fuel tank cap depends on different situations: 1. To open the car fuel tank cap, turn it to the left; 2. To close the car fuel tank cap, turn it to the right. The fuel tank cap refers to the box on the car used to store gasoline, which is square in shape, made of stainless steel, has good sealing performance, and is located at the rear of the car. Solutions for when the fuel tank cap cannot be opened include: 1. Use a screwdriver to pry open the plastic clips fixing the fuel tank liner inside the trunk and remove them; 2. After removing the inner liner, you can see the locking mechanism of the fuel tank cap and the cable for remote operation; 3. Pull the cable, and the fuel tank cap can be opened.

I remember when I first started driving, I couldn't figure out the direction to open the fuel tank cap and ended up twisting it for a long time without success. Later, I found that most fuel tank caps are designed quite simply: turn it to the left to open, which is counterclockwise; after refueling, turn it back to the right to its original position, clockwise to close. The key is to tighten it a bit until you hear that clicking sound, indicating it's properly sealed. Otherwise, gasoline vapor leaking while driving is not only dangerous but could also trigger the anti-theft system alarm. Always ensure the engine is turned off during operation to avoid any sparks that could cause an accident. If it won't open, the cap might be frozen or the lock cylinder is stuck—try pouring some hot water or using a bit of lubricant, but don't force it to avoid damaging the cap. Make it a habit to check the cap after refueling, ensuring it's tightly closed before starting the car, which is both safer and more fuel-efficient.

It wasn't until I changed cars that I understood why the fuel tank cap opens to the left, just as naturally as opening a beverage bottle, by turning it counterclockwise to loosen. I think this design is quite user-friendly, making it easy even for beginners: stand in front of the fuel filler, twist the cap to the left to open it, and after refueling, turn it back to the right to lock it. Remember, there's an arrow indicator on the cap—just follow the direction and you won't go wrong. Don't use too much force to prevent the threads from stripping. Also, when washing the car, take a moment to wipe around the cap to avoid dirt buildup that might affect the seal. Replace the rubber ring promptly if it ages to prevent gas leaks. Once, I forgot to tighten it properly and got a scare from the smell of gasoline while driving. Now, I habitually give it two extra twists after refueling for peace of mind.

Handle the fuel tank cap with care: After the engine is completely turned off, grasp the cap and turn it to the left (counterclockwise) to open, then refuel; after finishing, turn it back to the right (clockwise) to ensure a tight seal. Not tightening it properly may cause fuel leakage, polluting the environment or causing a fire, so a click sound indicates it's properly secured. To check for leaks, smell for gasoline or look for liquid seeping from the cap's edges.

The way to twist the fuel tank cap directly affects maintenance: usually turn left to open, right to tighten. This sealing design is crucial; improper twisting can allow dust to enter the tank and clog the filter. I recommend feeling for resistance when twisting—if it's too loose, the rubber ring may be aging. During each maintenance, wipe the threads clean with a cloth to ensure smooth operation for years. Always twist the cap securely after refueling to prevent fuel vapor leakage, waste, and pollution.
