What are the reasons for the blown head gasket on a Cruze?
1 Answers
The reasons for the blown head gasket on a Cruze are as follows: 1. The engine frequently operates under overload conditions, leading to prolonged detonation combustion. Due to the excessively high local pressure and temperature in the cylinder, the head gasket is prone to failure. 2. When tightening the cylinder head bolts, the operation did not follow the specified requirements, resulting in uneven torque among the bolts, which prevents the head gasket from lying flat between the cylinder block and cylinder head. 3. The ignition timing is too early, causing detonation combustion during engine operation. 4. The quality of the head gasket is poor. 5. The cylinder head or cylinder block is deformed, or there are defects in the mating surface between them, with cylinder head deformation being more common. The Cruze is a compact car launched by Chevrolet, with body dimensions of 4450mm in length, 1807mm in width, and 1459mm in height, and a wheelbase of 2700mm.
