Quality Warranty Policy


Warranty Guideline

1.1 The complete engine is covered by a one-year warranty. Please scan the QR code and submit the warranty registration before installation.

1.2 The warranty period starts from the date the warranty registration is submitted. (Engines not registered for warranty will not be covered.)

1.3 Within three months of installation, wear-and-tear parts are covered under warranty. These parts include water pump, valve cover gasket, front and rear crankshaft seals, cylinder head gasket, spark plugs, and oil pan gasket. Warranty does not apply to failure of such parts beyond three months of engine installation.

1.4 Within six months of installation, issues such as valve wear, bearing wear, camshaft wear, chain elongation, and timing belt breakage are covered under warranty. Warranty does not apply to failure caused by such issues beyond six months of engine installation.

1.5 Within twelve months of installation, defects such as crankshaft breakage, connecting rod breakage, camshaft breakage, and valve breakage are covered under warranty. Warranty does not apply to failures beyond twelve months of engine installation.

2.2 Warranty does not apply to damages caused by coolant leakage or reduced coolant levels due to the aging of the cooling system, resulting in engine overheating or cylinder bed damage, is not covered.
