Bike Valve Caps

How to loosen tight valve cap on bike?
This is just a regular bike I use for riding around town. I get on it and ride it; I don’t know much technical stuff. Anyway, my bike had a flat tire last year. I took it to a shop to be fixed, then didn’t have to add any air till winter came and I put the bike away. It’s good enough outside to go biking again but now I need to add air to the tire. Well, the valve cap is incredibly tight! I simply could not get it off the tire. I struggled with it for half an hour just now and could not move it. I tried using pliers, I wore gloves for more traction, and nothing worked. It would not budge. It’s like the shop superglued the stupid thing back on when they fixed the tire. How can I get the valve cap off so I can inflate my tire?
P.S. Please don’t suggest taking the bike apart in any way. I don’t know what I’m doing and if I start taking apart pieces, I don’t think I could get them back on safely. I’d really like a simple solution that I can complete at home, if at all possible.
At this point, you may have a safety issue. Valve stems weren’t designed to be torqued with pliers. Take it back to the shop that put the cap on, they should remove it and check your stem with no charge. Expect to pay for a new tube if it is damaged.
You do know to turn that counter-clockwise when it is at the bottom or clockwise if at the top?

Topeak Presta Valve Extender $5.99 Topeak Presta Valve Extender. Deep-section rims are great for aerodynamics, but they’re not compatible with the short valves found on standard tubes and tubular tires. The Topeak valve extender adds length to short valves, so you’ll never find yourself stuck by the roadside with a flat and a replacement tube you can’t inflate. The 43mm long Topeak Presta valve extender is precision-machined from aircraft aluminum and screws onto the tube’s original valve, providing enough additional length to clear your aero rim and engage your pump’s chuck. A rod inside the valve extender screws onto the original valve’s lock nut, allowing you to close the valve to prevent accidental air leakage. Throw a Topeak valve extender in your saddle wedge or Cycling Jersey pocket and you and your riding buds will be good to go no matter what. |

You need to know for sure what problem there is, as heinadg in the wrong direction will be very expensive. These engines are chain driven cams so rarely fail. The only way to bend valves is to have a piston hit them so a broken cam shaft is possible. Once you know for sure what the problem is then you can decide on the best course of action.You will get to the position where you can cost out the repairs and decide to scrap or not. The body on these vehicles tend to give out before the engine does.
