Cylinder Block Plug
Mitsubishi FUSO®

The Cylinder Block Plug, also known as a freeze plug or expansion plug, is a small but important part of a commercial truck's engine. Its purpose is to seal off a hole in the cylinder block that was created during the manufacturing process. The Cylinder Block Plug is typically made of metal and is designed to withstand the high temperatures and pressures of the engine's combustion process. Without the Cylinder Block Plug, the engine's coolant could leak out of the hole and cause serious damage to the engine. In addition, the Cylinder Block Plug helps to maintain the engine's proper operating temperature by allowing the coolant to circulate through the engine. If the Cylinder Block Plug fails, it can lead to overheating and engine failure. Therefore, it is important to ensure that the Cylinder Block Plug is in good condition and properly installed.
