No ( not unless you want to wreck the engine )
If the freeze plug is " blown " than the engine coolant will
just pour out
The engine will leak out coolant/antifreeze from the freeze plug area. Freeze plugs can be replaced, it may take a lot of work to replace one but they are made to be replaceable. It is not advisable to drive any vehicle with a blown freeze plug.
drill a hole in it install a screw and pry it out then drive in a new one
The hardest part of the job is GETTING TO the freeze plug. Depending on which one is leaking, sometimes you need to pull quite a bit of stuff just to get to the freeze plug. You need to be able to examine it and have clear access to the freeze plug and if it's one of the rear plugs (under the flywheel), you're only option is to pull the engine and/or transmission. Once you can get to it, just drive a screwdriver or other sharp object through the freeze plug and pry it out. Clean the block around the freeze plug then install one of the aftermarket types, preferably one that allows you to tighten a bolt to install it. You'll have trouble getting an original type freeze plug to seal if you don't have the engine block sitting on a workbench. Any time you have an engine machined, always replace the freeze plugs.
Take a punch and drive one side of the plug inward. Then grab the other side of the plug with pliers and remove it.
if it works, don't worry, the bulb has just blown if it doesn't work, then it's probably dead, bin it and buy another one
You will either have to remove the transmission are pull the engine out. It is what ever you think will be the easest for you. Then just knock the plug out, clean the hole with sand paper and drive the new one back in with a hammer and a socket that will fit in the freeze plug. Then put it all back together. There are 2 plugs in the back of the engine, replace both of them. You will see 1 plug in the center of the back of the block that is not a freeze plug, it is a cam plug do not bother that unless it is leaking engine OIL. Leave it alone.
There isn't just ONE freeze plug; there are many, and they're all in the "water jacket" surrounding the cylinders.
There are about 8 freeze plugs which one is leaking?
take a punch or chisel and pop the old one out the take a socket the size of the freeze plug and hammer it in
It depends on the freeze plug. Generally though, pull everything out of the way so that you can get to it. There may be one or more in the BACK of the engine, so to get to those you will need to separate the engine and transmission.If it's a side freeze plug, for example behind the starter, you would need to pull the starter and anything else that might hinder access to the freeze plug. Then, pull the freeze plug out using whatever method you find acceptable. Generally, if the freeze plug is rusted, you can put a large screwdriver or small pry bar into the weakened area then pry out the freeze plug.Once the old plug has been removed, clean the opening and install the new one. If you have the type with the tightening screw, just tighten it in to seal it. Otherwise you'll need to press in the new one, making sure to get a good seal.
blown head gasket OR if in only one cylinder then maybe the plug was loose?
NO you do not. Just remove whatever is in the way so you can get to it. Then drive it in sideways and pull it out. Then drive the new one in it's place. No big deal.
