How do you remove sump nut its tight?

To remove a tight sump nut, first ensure that you're using the correct size wrench to avoid rounding the edges. Apply penetrating oil to the nut and let it sit for a few minutes to help loosen any rust or debris. If it’s still stuck, use a breaker bar for added leverage or gently tap the wrench with a hammer to help break the seal. Always be cautious not to apply too much force, as this could damage the surrounding components.
