Volvo Freeze Plug - ProParts Sweden 463904

Product Information

An engine expansion plug, also known as a freeze plug or core plug, is a small, round metal or rubber disc inserted into the engine block. Its main function is to seal off passages created during the manufacturing process of the engine block, where sand cores were used to create the internal coolant channels. Additionally, expansion plugs offer some protection against cracking in extremely cold temperatures by allowing room for expanding coolant if it freezes.

• Coolant Leaks: A common sign of a failing expansion plug is a visible coolant leak around the plug area. You may notice coolant pooling underneath the engine or dripping from the plug location
• Overheating Engine: Leaking coolant due to a failed expansion plug can lead to reduced coolant levels, which can eventually cause the engine to overheat due to insufficient cooling
