freeze out plugs are metal plugs in the block and heads of your engine. they are are there if the coolant was mixed wrong with to much water and the vehicle freezes they will pop out allowing expansion of freezing liquid hopefully saving the engine

Part 2: You will see these called freeze plugs, casting plugs, welsh plugs and probably other terms. The holes they plug are part of the cylinder block casting process to allow molten steel/iron/aluminum to rapidly flow into the block casting mold. The fact that they will pop out if the coolant in the engine freezes can be serendipitous but in most cases the plugs go bad due to galvanic action: the steel plugs installed at the factory are dissimilar to the engine block metal and will start to corrode (rust) and will start leaking after a while. This is why most antifreeze manufacturers claim they have anti-corrosion protection; it is also why 99% of replacement plugs are brass. Three points to remember: 1) before replacing plugs do your research and find out EXACTLY how many plugs your engine has and where they are. 2) if you have to replace one plug, replace them all. 3) if you are rebuilding an engine it is cheap insurance to replace the plugs.

Locate the bad freeze plug and remove parts that impede the facilitation of reaching the plug. Take a screwdriver and hammer out the old plug. Replace the plug with either a regular plug (a socket that fits the inside of the freeze plug helps) or a rubber expanding freeze plug.

How do you install an engine block heater 2004 Chevy trail blazer V6-4.2L?

First check and see if there is a pouch located directly beside your battery. If there is a pouch it will contain a plug that is for the factory engine block heater. If there is no plug then you can pursue an aftermarket type. There are several types. If you want to use a freeze plug block heater, you'll need to have someone help you remove a freeze plug. That usually requires that you remove a lot of the peripheral equipment until you can get a clear access to one of the freeze plugs. Measure the freeze plug then go to an auto parts store and purchase a freeze plug block heater of that specific size. Once you have one that will fit into the hole, you can drill a hole in the freeze plug, then use a prying instrument to remove the old freeze plug. The block heater freeze plug usually goes in with a nut to tighten the freeze plug into the hole. BTW, you'll get a lot of antifreeze all over when you do this, and plan on taking your time since it will be time consuming.
