What to Do When the Car Fuel Tank Cap is Frozen?
2 Answers
If the car fuel tank cap is frozen, it can be resolved through the following methods: 1. Method One: Cover the car fuel tank cap with a cloth, then gently tap the cap to break the ice and unlock it. 2. Method Two: If the fuel tank cap is frozen solid, pour warm water over the cap to open it, then remove any remaining water. 3. Method Three: Open the trunk and locate a red or green pull cord (the emergency fuel tank cap release cord) near the fuel tank cap. Repeatedly pull the emergency release cord several times.
I once encountered a frozen fuel tank cap during a sudden cold snap when temperatures plummeted to -10°C. I initially tried pouring hot water directly on it, nearly scalding myself, before learning the proper method: applying a warm, damp towel to the cap followed by gently heating it with a hair dryer on low setting for a few minutes. Prevention is straightforward—always ensure the cap is tightly closed after refueling, clean dust and moisture from the sealing ring, and periodically apply silicone-based lubricant to maintain smooth operation. If attempts fail, avoid prying forcefully to prevent damaging the tank or seal; instead, safely call a repair shop for assistance. Ultimately, these winter maintenance details matter—don’t repeat my initial recklessness.
