How to Install Freeze Plugs

The installation of freeze plugs can be a fairly simple task. There are very few steps and minimal effort involved. This is a useful skill to have because regular maintenance on your car's freeze plugs can prevent your engine block from cracking, which would cost you a bundle to repair. Also, freeze plugs are fairly inexpensive to obtain and will not hurt your pockets too bad. Engine maintenance is not always the nightmare it appears to be.

Things You'll Need

• Hammer
• Punch
• Pliers
• Emery cloth
• Socket or seal driver
• Sealant

Instructions

Remove the Old Freeze Plugs

1. Remove the old freeze plugs from the engine block using a hammer and punch. Place the punch at the side of the plug and tap it with the hammer using the necessary force.

2. Pull the old plug out using the pliers.

3. Clean any rust or build-up from the freeze plug's mounting surface using the emery cloth.

Mounting the New Plugs

1. Mount the new plugs using a socket or seal driver.

2. Make sure the socket is correctly sized if you are using one.

3. Apply a small amount of sealant to the plug.

Tips & Warnings

• The easiest time to install freeze plugs is when the engine block has been removed from the car and placed on an engine block stand, which is a useful device that holds the engine block during automotive repairs or maintenance.

• Do not use sealant on rubber plugs.
