Key Maintenance: Check the Sealing Gasket Regularly

The engine drain plug is a critical component of the engine cooling system, typically installed at the bottom of the engine block or radiator. Its primary function is to drain coolant, sediment, and debris from the system, ensuring optimal cooling performance and preventing internal corrosion. It consists of a plug body (usually metal) and a sealing gasket (rubber or copper) to prevent coolant leakage when tightened.

The sealing gasket of the drain plug is prone to aging, hardening, or cracking after long-term use, which can cause coolant leakage. Leakage not only reduces the cooling efficiency but may also lead to engine overheating. It is recommended to inspect the gasket during routine maintenance and replace it with a model-matching one immediately if signs of wear are found.

The rocker arm assembly is a core component in many mechanical equipment, especially in automobiles, construction machinery, and some heavy equipment, playing a crucial role. Below, we will provide a detailed introduction to the relevant knowledge of the rocker arm assembly.
