Engine Expansion Plug Kit from Evergreen

An engine expansion plug kit includes the expansion or freeze plugs that seal casting openings in the block and cylinder heads. Most rebuilders replace them all while the block is bare.

When to Replace

Coolant leaks from corroded plugs
Block cleaning or machining during a rebuild
Plugs pushed out by freezing

Installation Tips

Clean each bore and check for pitting
Use a sealant suitable for coolant contact
Drive cup plugs on the flange, not the center
