My '02 camaro has a small leak on the rear of the motor I cant pinpoint whether it is the head gasket or the intake manifold gasket. For about a week it was running fine even with the leak, but as of late it buried the guage way past 260 degrees causing it not to accelerate at all and pretty much lose power and smoke severely. One of my friends suggested that my thermostat may have stuck closed. What are your thoughts on the matter
Do you

Freeze plug is another name for core plug or expansion plug, and is commonly referred to as a "frost plug." They are a subset of the plugs on a car engine cylinder block or cylinder head. The traditional plug is a thin, domed, disc of metal which fits into a machined hole in the casting and is secured by striking or pressing the center to expand the disc.

A true freeze plug is an expansion plug located in the side of an engine block that is supposed to protect the block against freeze damage. Water expands when it turns to ice, and if the coolant does not have enough antifreeze protection it can freeze and crack the engine block. The freeze plugs (there are usually several) are supposed to pop out under such conditions to relieve the pressure on the block.

Most of the plugs to be found on an engine are actually to plug the holes where sand cores have been held. The sand cores are used in the casting process to form internal cavities in the engine block or cylinder head, for cooling water for example, and so should really be referred to as core plugs.

Freeze plugs can often be a source of troublesome leaks as a result of internal cooling system corrosion. Ease of replacement depends on accessibility. In many cases the plug area will be difficult to reach and using a mallet to perform maintenance or replacement will be nearly impossible without special facilities. Expanding rubber plugs are available as replacements when access is a problem.
