How Remove stuck radiator cap?

To remove a stuck radiator cap, first ensure the engine is cool to avoid burns. Wear gloves for protection, then try twisting the cap gently while applying steady pressure. If it’s still stuck, use a rubber band or cloth for a better grip, or tap the cap lightly with a rubber mallet to break any corrosion. If these methods fail, consider using a penetrating oil around the cap’s base and letting it sit for a while before attempting again.
