Freeze/Core Plugs
A freeze plug, also known as a core plug or expansion plug, is a vital component in an engine's cooling system, designed to prevent damage caused by freezing coolant. These plugs are typically installed in various locations throughout the engine block and cylinder head, covering passages that are used during the casting process. In the event of freezing temperatures, the freeze plugs are designed to pop out, relieving pressure and preventing the engine block from cracking due to the expansion of freezing coolant. While they are often referred to as "freeze plugs," their primary function is actually to protect the engine from damage caused by overheating, not freezing.

When selecting the correct freeze plug for your vehicle, there are several factors to consider to ensure proper fitment and performance. Firstly, determine your vehicle's specific make, model, and engine configuration, as freeze plugs are designed to fit particular engine types and sizes. Consider the material and construction of the freeze plugs, opting for high-quality materials such as brass or steel for durability and resistance to corrosion. Pay attention to the size and shape of the freeze plug, ensuring it matches the dimensions of the engine block or cylinder head opening for a secure and leak-free seal.
