Multiquip 12251Z5K003 Cylinder Head Gasket GX270UT2SMXC

The Multiquip 12251Z5K003 is a genuine OEM Cylinder Head Gasket GX270UT2SMXC designed for GA3.6HR, MVH308GH, and MVH208GH equipment. As a direct Multiquip OEM part, 12251Z5K003 is manufactured to the exact tolerances required by the GX270UT2SMXC engine, ensuring a correct, leak-free seal between the cylinder head and engine block. This gasket is a direct-fit replacement for generators and heavy-duty reversible plate compactors in the GA and MVH families. Keep a spare on hand for planned maintenance or unscheduled engine service to get your equipment back up and running without delay.

Key Features

• Engine-Specific OEM Sealing Material — Manufactured to the exact material grade and compression specification required by the GX270UT2SMXC engine, ensuring a consistent, long-lasting combustion seal.
• Direct-Fit Installation — Bolt-hole pattern and fire-ring positioning match the OEM cylinder head layout exactly, dropping straight into place without trimming or adjustment.
• Confirmed Fitment — Verified for GA3.6HR gasoline-powered generators, MVH308GH heavy-duty reversible plate compactors, and MVH208GH heavy-duty reversible plate compactors.
• Maintains Full Combustion Pressure — A correctly seated cylinder head gasket preserves compression and prevents coolant or oil intrusion into the combustion chamber, keeping the engine running at rated power output.
• Critical Fuel and Emissions Safety — A failed head gasket can allow combustion gases to escape externally; replacing with a genuine OEM part restores the sealed integrity required for safe engine operation.

The cylinder head gasket forms the critical seal between the engine block and cylinder head, containing combustion pressure while keeping oil and coolant passages separated. On the GX270UT2SMXC engine found in the GA3.6HR, MVH308GH, and MVH208GH, a compromised gasket typically presents as loss of compression, white exhaust smoke, overheating, or oil contamination. Replacing a worn or blown gasket with the correct OEM part — Multiquip 12251Z5K003 — restores proper sealing and protects the engine from further internal damage.
