A freeze plug is in the engine block itself; they look like small round caps pressed into the block. Get a Chilton or Haynes repair manual from a parts store.
from mbrown3039: There are only a couple of freeze plugs you can get to without removing suspension components or pulling the engine entirely (btw, any engine overhaul should include replacing the freeze plugs -- they're only a dollar or two each, so take the time to do it if the engine is already out for any reason), but the key is to make sure you get the correct size and then tap it into place using either a plug tool (the preferred method, as it will make sure you have seated the plugs evenly and to the correct depth) or by placing a socket just smaller than the plug inside the lip of the plug and using a socket extension and hammer to tap it into place. Take your time and buy a couple of extra ones in case you damage the first one when installing it -- since you'll lose most of your coolant when you remove the old plug (have a bucket handy!), you'll be without a car until you complete this repair and add more coolant. Good luck!

Is there "Freeze Plugs" on a 1994 Mercury?

Virtually all engine blocks have freeze plugs. They serve two purposes:
  1. They are designed to burst out of the block in case the engine coolant freezes, preventing a cracked block.
  2. They allow for a more thorough cleaning of the engine block when the block is "tanked" during rebuild/remanufacture.
One thing to consider...what weight of motor oil are you using during the bitter cold months? Heavier weight oils get very thick on the cold mornings. This makes cranking harder and increases engine wear. Check with a local dealer and see if the manufacturer has any suggestions for a thinner oil in the cold months to make starting/running easier.

I have a GMC 1994 Suburban with a coolant leak in the bottom of the engine, driver side, comming out of a round plug, that has wires going a plug on it. I have a picture I can email you...and just need...

If it's a round, cup shaped plug, about 2" or so... It's called a freeze out plug. These do corrode over time and leak. They are kind of a pain to replace, and I recommend using the correct tool to install the new one. (Freeze out plug installer tool.) These are meant to "pop" out if your coolant freezes so not to crack your engine block.

How do you fix a freeze plug on a 1987 BMW 325

To remove purchuse a slide hammer can be rented from many auto stores. Drill small hole in center of plus and using the screw end on the slide hammer screw in drilled hole. The hole drilled should ne smaller than the srew end on the slide hammer. Slide hammer until plug comes out. To install: place new plug over block opening and using a socket that fits inside of the center of plug simply hammer until freeze plug is flush with block. I would suggest using fine sand paper and clean up outer edges of block hole surfaces before installing.

Water leking behind motor

You'll need to knock out the old one. They make a freeze plug installation tool, or you can use a socket to pound in the new one. Also, they have expandable rubber freeze plugs that don't have to be pounded in.

They do make a "tool" to install them. It keeps it true and straight, and if it isn't it may pop out. Also, take a look at the hole, to see it it's pitted. The plug should go in firmly.

I have a 1994 BMW 318i, the computer got wet and shorted out so I replaced it. Now there is no spark to the spark plug.

Verify the TDC Cam sensor on the left front of the engine, disconnect and clean it and reconnect.
