This is a tuff freeze plug to get to. If the plug is fully exposed you can punch a hole it and pry it out with a screw driver. Once out you can replace it with an expandable rubber freeze plug to get the job done in the car. If not this may require pulling the drive train down to get at it or pull the engine to make the repair. Feel the freeze plug with your fingers to determine the best route.

It is likely one of you coils. You can buy one and keep moving across all the cylinders until you find the bad one or wait for it to set a code to tell you which one.

yes about the upper intake and the only way i know how to check the coils is with a engine anilyser or if the check engine light comes on then you can have the codes pulled and that will tell you which cylender is missfiring this engine has a indevidual coil for each spark plug so thares 6 of them and thay slide right down over the sparkplugs

Where is the freeze plug on a 1996 mercury villager

Freeze plugs run along the side of the engine block. There are some also between the rear of the engine and where the transmission mounts that you can't see when there connected. Some can be difficult to change depending on which ones are leaking. Sometimes accessories or motor mounts have to be removed to gain access, again depending on which one is leaking.

Will the engine lock up if the freeze plugs are leaking?

The advantage of the rubber expansion plug over a regular freeze plug is they are easier to install when there is very little room to work. But either way, you have to get to the old plug to remove it. You may have to work on it from underneath the car with the car up on jackstands or blocks. If the leak is along the lower side of the engine block, it probably is a freeze plug.

2001 ford taurus 3.0-engine leak behind left rear engine head-car runs good-does not overheat-cannot find leak-no leaks in radiator or heater hoses or water pump.

It may be the freeze plug in the back of the head leaking, it looks like a small round cup about the size of a quarter it presses into the back side of the head, to remove hit the outer side of the inside of the cup with a screwdriver and hammer. To install use the apropriate size deep well socket with extension to hammer the new one in don't hit it in too far just until flush and also use permetex black sealant around the rim before installing to ensure a good seal also drain antifreeze completely before attempting job and be sure the seat where the freeze plug is going into is clean and dry.

My 2001 ford taurus is leaking coolant on the firewall side of the engine. is there a coolant hose on that side that could be leaking?

It could be a hose on top of the engine leaking back there. It could also be a freeze plug on the back of the engine. Its a round disk about 2-3" in diameter and is recessed about 3/8" into the block. Check those out and make sure all hoses are good and tight. Any hoses that are kind of puffed out above the clamp should be replaced

Leaking antifreeze fluid from under the engine.

might be a freeze plug leaking, or heater hose. there are three freeze plugs on each side of engine and two in back of engine. most likely if any of them are leaking, it will be the one behind the starter on the far right rear of engine block. they have also been known to leak around the front and rear of intake, where intake, head, and block meet.
