my valve cap is leaking slowing how do i fix it what part do i need
valve cap? like on the tire? shouldn't leak...replace valve stem
It might be just the core that is leaking but I would have a new stem put in to be on the safe side.
The cap on the valve is just a dust cap designed to keep dirt out of the valve. To determine if the valve is leaking, move the car until the valve is at the bottom pointing up. Put a little water into the valve and watch for bubbles. Bubbles confirm the valve is leaking. You could try replacing the core with a little valve wrench (you will lose all the air in the process) or go to a service center and have them replace the valve. You cannot replace the valve yourself. If no bubbles, you have a leak in the tire or where the tire joins the wheel. Any tire service center can find and fix the leak.
