This 6061 aluminum bleeder screw (Part Number: 10010) is a great upgrade for the OEM plastic one. It fits 2001 - 2016 GM 2500HD/3500HD models with 6.6L LB7/LLY/LBZ/LMM/LML Duramax engines. Over time, the plastic bleeder screw can crack from repeated use, causing air leaks, stalling, hard starts, or other driveability issues. This black anodized aluminum bleeder screw gives you reliable performance and peace of mind. It's perfect for replacing a cracked screw.

Using this bleeder screw is easy. Just remove the old plastic screw and install this new aluminum one in its place. Make sure it's tightened properly to avoid any air leaks. As for maintenance, there's not much you need to do. Just keep an eye on it during your regular vehicle checks. If you notice any signs of damage or if the screw becomes loose, replace it right away. Also, remember that this screw is designed for specific GM Duramax models, so don't try to use it on other vehicles.
