Water plugs are called welsh plugs you should get one from a cylinder head place or engine reconditioner. They come in various sizes so you will have to talk to them & give them info on the motor to get the right one. The plugs shouldn't fall out cause they are interferance fit (knock in) is it a nice round or oval hole? does it leak water there?
This sounds like the block heater for your car's engine, the engine coolant heater with a cord that you p[lug into household current to keep engine warm during very cold nights. It makes for easy starting/warm-up of the car on cold mornings.
Use a small socket on the screw (I think it is a 5/16 head screw) and see if you can tighten it about a 1/2 turn or less (or until the heater element rim is snug against the engine block) to try and stop the leak. If that doesn't work, it will need to be removed to reseal it. This means you will have to drain the coolant from the car first. Then loosen that screw several turns to release the clamping-type wing nut on the other end of the screw inside the block. There is a rubber o-ring around the element that is leaking. Pull the element out, and watch out for a cup or two of coolant to also drain from the engine block. Now you have it out, you can decide whether to just replace the o-ring, or buy a new block heater with a new o-ring included (they're not too expensive), or just install a new freeze plug (like $2.00 at a parts store) in the hole if you don't care about having the block heater on your car. Be sure and clean the area well, around and inside the hole where the o-ring goes, so you get a good seal when you put it back together. Good luck.
Not comming from the speaker! Make sure that the rubber door trim aound the door is intact and not damaged. Additionally, check the rubber seal on the outside of the window where it retracts into the door. These are the only 2 ways that water can enter through the passenger door.
Could be a hose, could be a soft plug, could be a water pump, could be an intake gasket. Need a little more information, couldn't the people who found the leak tell what was leaking? You will probably have to get under it and look around and see where the water is coming from. Please rate my answer so I am rewarded points for it.
Epoxy or other types of "quick fixes" will not work, or if they do won't fix the problem correctly. Even stop leak just plugs the hole from the inside, and plugs up the system. Best bet is to try and find the problem, which is usually a leaking hose, water pump, or radiator. Once you find where the leak is coming from I can advise better on the best solution.
Ron, There are 4 different versions of the 3.0 engine used in the 1998 model Taurus. Hard to give exact info without the exact version of the engine. First check for any coolant hose above the leak area. Next, look for "soft plugs" located in the cylinder head near the leak. Usually these are very hard or impossible to see, as they are covered by the exhaust manifold. You might have to remove the exhaust manifold to see them. There are also a number of soft plugs located in the rear of the engine block, and on both sides of the block [iron blocks only] If you have a leaking soft plug, the best bet is to replace all of them. Why? Because you have neglected changing your antifreeze in a timely manner. Now it's time to pay the price for that negligence. All the soft plugs will be rotted about the same amount. If you only replace one now, you will be replacing more of them in the coming weeks and months. If this is a high mileage or ratty car, it may be wiser just to junk it. Deferred and neglected maintenance ALWAYS costs more to fix in the long run. The Germans have a saying, "The lazy man, works the hardest of all"
If it smells like antifreeze it's your heater core. If it doesn't smell and you have been using your a/c then it's your condenser or maybe a blocked drain tube. If it's been raining a lot or if you noticed after going threw car wash could be door seals, or even a windshield seal.
I had the same problem with my voyager. it was the "freeze plug" or "soft plug" on the side of the engine block. It is about an hours work for a shop and cost me about 127 dollars. They do make an expanding plug as a replacement which I purchased to carry just in case another failed. The main issue is getting the old one out because of it's location. Hope this helps.
here is how I have done it. drain out coolant from engine. get under car and find the bad soft plug. next you can drill a hole in it and screw a big screw in it, to take it out. but be very carefull not to knock it in engine, for you may not be able to get it out. next when plug is out, clean arond the hole in engine. after cleaning it is best to put gasket sealer or similar all around soft plug. then tap it in the engine block very carefully. make sure its in there as far as old one was. let it sit for a bit, then readd coolant and start car to check for leaks. bevel side of soft plug in engine.
