What should be paid attention to when replacing the cylinder gasket of Roewe 350?
2 Answers
When replacing the cylinder gasket of Roewe 350, pay attention to: when removing the cylinder head bolts, it must be done after the engine is completely cooled. The removal should follow the principle of evenly loosening from both sides to the middle diagonally; the selected cylinder gasket must be a quality-assured original factory accessory that meets the requirements. The function of the cylinder gasket: The cylinder gasket is one of the most important gaskets in a car. Its function is to ensure the sealing between the cylinder block and the cylinder head joint surface, preventing gas, water, and oil leakage. Characteristics of the cylinder gasket: It is usually made of thin metal sheets wrapped with asbestos. Nowadays, pure metal gaskets are also used. Due to the harsh working environment, it requires heat resistance, corrosion resistance, sufficient strength, elasticity, and thermal conductivity to ensure reliable sealing.
I often work on cars like the Roewe 350, and replacing the cylinder head gasket is no trivial matter. The engine must be completely cooled—wait at least a few hours before starting, otherwise there's a high risk of burns. When removing the cylinder head, use the right wrench to loosen it gently, and protect the pipe connections to avoid damage. Cleaning is the most critical step: the surfaces of the cylinder block and cylinder head must be scraped perfectly clean, with no traces of old gasket residue or oil stains left behind. Otherwise, the new gasket won’t seal properly, leading to air or coolant leaks. The bolts on the Roewe 350 have a specific tightening sequence and torque—consult the manual. Generally, it’s tightened from the center outward in three stages to avoid warping. After installation, refill with new coolant, start the engine, and let it idle for 10 minutes to check for unusual noises or leaks. The whole process requires patience—take it step by step, with no room for carelessness. Done right, a single replacement can last for years.
