There are several tools made for doing this in the vehicle. The hardest part is gaining access. (sometimes it's nearly impossible without removing or partially removing the engine.) There are "factory" design plugs (cup type) and several versions of expandable ones. I try to use factory type wherever it's practical, opting for the others only when you just can't get anything else to work. Glue and sealants will not work.
To remove a plug, just hit it with a hammer & screwdriver inside one edge and grab it with channel locks etc and pull it out. Only requirement to installing is to keep it perfectly straight as you tap it back in (easier said than done). When I built engines I always used brass marine plugs in everything except race engines (never last long enough for a plug to rot out)...Brass plugs will outlast the engine, but are softer and not easy to install except on an engine stand.

Drain the antifreeze from the system as much as you can into a container or pan. Using a punch put a hole at the edge of the frost plug and pull them out. When replacing them use something that is the same size as the inside of the plug and lightly tap into the hole. Do this for each plug.
Good luck.

You need a spechial tool for pulling them out. it has the same principle as a hammer's fork but this tool is long skinny has just a prying edge. you need to get your self and tool into position and then pry it out.
that's the esay part.

if your installing a block heater then you should probly drain the coolant first.(not all but al least half *and from the block not the rad*) then note the instalation method described on the package if you have one. if not you need to "dip" in the heater part of the block heater into the block and then sit it flush. make sure you put a locking sealant around the out side sealing surface of the heater plug. (*this should be supplied, if not a local auto store has what you need) then install and make sure it's flush. no gaps no bends no nothing. if it's not flush then it will leak and push your newly installed cap out and then you need a brand new out. this is a one time shot.

Freeze plup location


Back of engine, eh? The freeze plugs (3, maybe 4 on that back side) will be on the engine block, below the cylinder head, and below where the exhaust manifold mounts up. Look in back of the exhaust manifold for the plugs. Check for indication of leaking, it should be evident. If you have an engine block heater installed in one of the freeze plug holes, that may have loosened and started leaking. If you find a plug that needs replaced, put a stout screwdriver or punch on the freezeplug, not at the center of plug but to the edge, and whack it good. That edge will go in and the other side will stick out- grab with pliers and remove. Clean the area well to remove rust and scale where freezeplug seals in the block. It will be hard, possibly, to put in a new freeze plug with everything in the way. So buy a rubber expansion plug at the parts store-easy to install, just put a wrench on it to tighten. Take your old freezeplug with you to get the right sized expansion plug.
Good luck, hope you find it.

Freeze plug


If you can access the freeze plug it is not too hard to replace it. Drain the coolant. Remove the old plug and tap in a new one. The parts are inexpensive. Getting them out and put back is the hard part. Refill with new antifreeze. Run, check for leaks, then top off the system.

Replace freeze plug


Use a screw driver and hammer to tap one side of the old freeze plug in. This will turn it side ways in the hole. Use a pair of channel locks to grab it and pull it out. Use some Permatex Ultra Copper silicone around the edge of the new plug. Use just enough to put a light coat on it. Put the new plug up to the hole and take your hammer and lightly tap all the way around the plug evenly until it is flush with the block.

Leaking water from engine block "freeze plugs ???


That means that you have a rusted out freeze plugs so you can buy a freeze plug that can be screwed into place if you can get to the reeze plug, however if it's behind the exhust maniforl you will have to remove the exhaust manifold to get to them. you will need a short hammer and chisal to knock out the old freeze plug. then a wrench to put in a new freeze plug unless you want to put in standard plugs but it is not easy. the freeze plugs rusting are common for this rig. the Freeze plug that has a threaded nut and bolt and made out of high heat rubber is about $5.00 each and can be bought at any Nappa Auto parts or Advance auto Parts store all complete kit for all of them for the stamped steel is about $10.00 however there is one behind the transmisson and hopefully it is not leaking. If it is leaking th transmisson has to come out. Good luck and if you need help just reply to the e-mail you recieve from this site. Thanks for using fix-ya.

Hole in freeze plug; water pours back out


Hi, the freeze plug is removed from the outside of the engine, so if it already has a hole in it, put a screw driver in the hole and prize it out, then the new one simply taps back in. As for the size, once you have removed the knackered one, just simply match it up

Frost Plug


The engine freeze out plugs are all one size. The block heater takes the place of a freeze out plug.
