What Causes Freeze Plugs To Blow Out: Key Reasons Revealed
Freeze plugs are crucial in your car’s engine. They help prevent damage due to freezing. But sometimes, freeze plugs blow out. Why does this happen? Let’s find out.
What Are Freeze Plugs?
Freeze plugs are also called expansion plugs. They are small metal discs. These plugs are found in the engine block. They are designed to pop out if the water inside the engine freezes. This helps prevent the engine block from cracking.
Common Causes of Freeze Plugs Blowing Out
There are several reasons why freeze plugs blow out. Here are the most common causes:

- Improper Installation: Sometimes, freeze plugs are not installed correctly. If they are too loose, they can blow out.
- Engine Overheating: High temperatures can weaken the freeze plugs. This makes them more likely to blow out.
