Key Features

• Genuine OEM Sealing Integrity — Manufactured to original specification, ensuring the plug seats and seals correctly within the lower cylinder head plate without risk of leakage or improper fit.
• Direct Drop-In Replacement — Threads and dimensions match the original factory plug, allowing straightforward installation into the DCA25SS generator cylinder head assembly.
• Broad DCA25SS Series Coverage — Compatible with DCA25SSI, DCA25SSIU, DCA25SSI2, DCA25SSAI, and DCA25SSIU-GEER models, covering the full range of Multiquip 25kVA ultra-silent generator variants.
• Engine Block Protection — A properly seated cylinder head plate plug prevents coolant or oil intrusion into critical engine passages, maintaining correct fluid routing and engine operating conditions.
• Fuel and Fluid System Safety — On diesel generator engines, a failed or missing lower cylinder head plate plug can compromise internal pressure boundaries — using the correct OEM plug supports safe, compliant operation of the generator system.

The lower cylinder head plate plug is a threaded sealing component that closes an access or service port on the cylinder head plate of the engine block. It maintains the integrity of internal fluid passages by preventing leaks and keeping contaminants out of the engine's lower cylinder head area. When this plug is missing, damaged, or improperly seated, it can result in fluid loss, pressure imbalance, or engine contamination — all of which can lead to accelerated wear or generator failure if left unaddressed.
