Freezing of the car gas tank cap is a fairly common problem in frosty weather. It is especially unpleasant and problematic when such a situation occurs on the road, and at this time it is necessary to refuel the car. You can improve the practicality of the vehicle and make it more stylish with the help of tuning, the accessories of which are available in our catalog at the link .

If the gas cap is frozen

Such a problem arises when an abundant amount of moisture at sub-zero temperatures gets on the car body and penetrates into the cracks. In this case, we suggest doing one of the following:

  • Drive the car to a warm place: garage, box, car service. After a few minutes, the frozen ice will thaw and the hatch will open.
  • A hairdryer can be used. However, if there is no power source, then this method will not work. Use the hair dryer carefully so as not to damage the paintwork.
  • You can also use car exhaust gases. If there is a hose of a suitable size and diameter, then due to the temperature of the exhaust gases, you can thus warm the fuel tank cap. To do this, just hold the hose for a few minutes in the direction of the hatch itself.
  • Apply a special fluid that is sold in car dealerships.

How to avoid freezing the gas cap?

Here are some tips on how to avoid this situation:

  • Before the onset of the cold season, it is recommended to lubricate the hinges of the gas tank cap with a special silicone grease. This mixture minimizes the risk of freezing, and you can buy it at a car dealership.
  • Many car owners use WD-40 fluid, but this method has little effect.
  • In frosty weather, after washing the vehicle, it is recommended to blow compressed air through all cracks and holes where moisture can accumulate.
