Features
- Dimension 1"3/8 inch (34.93 mm)
- Cup-type design for reliable sealing
- Protects water jacket against frost damage
- Seals casting holes in engine block
- Essential during engine restoration
★ Always replace all expansion plugs during an engine overhaul to prevent leakage. Check the bore in the block for damage before installation.
Installation notes
Install with the dome facing outward. Carefully tap the plug into the bore until it sits flush with the block, then give a short tap in the centre to expand and lock the plug. Preferably use an installation tool with the same diameter as the plug. Use a suitable sealant for additional security.
Compatibility
Note: engine blocks use different sizes of expansion plugs. Always check the bore diameter before ordering. Standard cup-type plugs are suitable for original bores; for damaged bores, an oversize plug or modified bore may be required.
Historical context
Expansion plugs were originally called 'freeze plugs' because they could push out in extreme frost to protect the engine block from cracking. In reality, they are casting plugs that seal the openings through which the coolant passage was formed during production.
