Core plugs seal holes cast in the engine block or cylinder head. To prevent leaks and stop your engine from freezing or overheating, find the right core plugs at the lowest prices on CarParts4Less.co.uk.
Core plugs are also known as ?sealing plugs', ?expansion plugs' and ?welch plugs'. The reason there are holes in your engine and cylinder head is because they were cast in sand. These holes give the manufacturers an easy way to remove excess sand after casting. Core plugs are made of rubber or metal and they fill these holes in different spots. This also helps strengthen the engine and cylinder head, and stops them from cracking when the coolant freezes. Core plugs suffer wear and tear with age and can dislodge. This can lead to coolant leaks, which in turn may cause the engine to overheat. To find the exact replacements for your vehicle, please fill in your details using the parts-finder tool on this page.
