The Multiquip 12251Z5T003 is a genuine OEM Cylinder Head Gasket designed for a wide range of Multiquip equipment including GA6HB, GA6HEB, GAW180HE, GAW180HEA, GAW180HE1, MC12PH, V305EH, MVH408GH, and MRH800GS models. As a genuine OEM component, it is manufactured to the exact material composition and dimensional tolerances required for a proper combustion seal. This is a direct-fit replacement that installs exactly like the original, with no modification needed to mating surfaces or hardware. If your engine is showing signs of coolant loss, compression drop, or exhaust leaks at the head, the 12251Z5T003 is the correct factory-sourced replacement to restore your engine to full working condition.
Key Features
- Genuine OEM Combustion Seal Integrity — Manufactured to exact thickness and material spec to maintain the correct compression ratio and combustion chamber seal for this engine family.
- Drop-In Head Replacement — Matches original bolt-hole pattern and surface profile for straightforward installation against the cylinder head and block mating surfaces.
- Broad Multiquip Model Coverage — Compatible with GA6HB, GA6HEB, GAW180HE series welders and generators, MC12PH mixers, V305EH and MRH800GS rollers, and MVH408GH plate compactors.
- Compression and Leak Protection — A correctly seated cylinder head gasket prevents combustion gases, oil, and coolant from crossing between passages — preserving engine power output and preventing premature wear.
- Fuel System and Engine Safety Relevance — A failed head gasket can allow uncontrolled combustion gas migration, creating both performance and safety concerns; replacing it promptly with the correct OEM part is critical.
The cylinder head gasket sits between the engine block and the cylinder head, forming a sealed barrier that separates the combustion chamber from oil and coolant passages. It must withstand extreme heat and pressure cycles with every engine revolution, making material quality and dimensional accuracy essential. When a head gasket fails, symptoms typically include loss of engine compression, white exhaust smoke, oil contamination, or visible leaks at the head joint — any of which can lead to serious engine damage if left unaddressed.
