Cylinder Head Plug Tap and Guide
Detroit Diesel

This cylinder head plug tap and guide set is engineered to facilitate precise threading and installation of plugs within the cylinder head. Proper sealing of these plugs is essential to prevent coolant, oil, or combustion gases from leaking, which could compromise engine performance or cause damage. The tap ensures clean, accurately cut threads, while the guide maintains correct alignment during installation. This set is critical when performing cylinder head repairs, replacements, or routine maintenance. Using dedicated tools reduces the risk of cross-threading or damaging the delicate threads in the cylinder head, thereby extending component life. High-quality construction guarantees durability and consistent results, supporting reliable engine operation. It’s recommended to source these tools from a trusted parts supplier to ensure optimal fitment and performance in heavy-duty engine servicing.
