Freeze plugs, also known as expansion plugs or core plugs, are typically located on the side of an engine block and are used to seal the holes left after the casting process.
The exact location of freeze plugs on an engine can vary depending on the specific make and model of the engine, as well as the number of cylinders. However, they are usually located on the sides of the engine block, with some located on the rear of the block as well.
To find the freeze plugs on your engine, you may need to consult the engine manual or a repair guide specific to your vehicle. It's also important to note that not all engines have freeze plugs, as some are designed to be permanent and do not require these plugs.
Freeze plugs, also known as expansion plugs or engine block heaters, are designed to expand and contract along with the engine block as it heats up and cools down. They are located in the engine block and are used to prevent the engine block from cracking due to the expansion and contraction of the metal.
In a 2008 Chevrolet Silverado 2500HD with a 6.0L engine, the freeze plugs are located in the following locations:
Two freeze plugs are located on the back side of the engine block, near the top.
Two freeze plugs are located on the bottom side of the engine block, near the front.
Two freeze plugs are located on the passenger side of the engine block, near the bottom.

It is impossible to propose a diagnosis without knowing the YEAR, MAKE and MODEL of your vehicle.
That being said, replacement of freeze plugs on any vehicle is not a minor undertaking. The mere failure of a freeze plug suggests poor maintenance of the vehicle over time, and is often a precursor of additional underlying cooling system damage.
To replace freeze plugs, often the engine must be removed, or at least decoupled from the car and elevated, to access the freeze plug location. Once you have access to the freeze plug location, you need to pry out the existing freeze plug, removing all rust deposits from the visible cavity and filing the freeze plug seating surface smooth, then use a mallet and large wooden peg to install the new freeze plug.
Once you are done, it is highly advisable to replace the thermostat in the vehicle, check the condition of the radiator, and be certain to maintain a 50/50 ratio of antifreeze to water, using only filtered water.
You must extract the freeze plug from the engine block, either using an extractor or a chisel, then clean the freeze plug seat of all debris and corrosion, then carefully install the new freeze plug using a wood block and mallet. Depending upon the location of the freeze plug, either adjacent components (exhaust pipes, starter, accessory brackets, etc.) must be removed for access. If the freeze plug is in a particularly difficult location, the engine may need to be removed from the car to service the freeze plug (in extreme circumstances).
