Hummm, seal the bolt threads with teflon tape, I prefer yellow but white works fine also. Be sure to pressure test when you are finished.

2004 Ford Explorer V6 engine over heating i replaced gasket, thermostat, top housing unit and the o-ring now it is leaking from behind the base where the thermostat housing is bolted down to just behind...

There is a gasket on the base of the housing, the housing you speak off has the sensor and a heater hose and bolts to top of the intake and also hold the thermostant, this housing does contain a rubber molded gaske, i have replaced a few of these, heres the problem i have run into a couple where the plastic was eaten away in the area that holds the gasket in place. if you remove it you will see a groove that the gasket sits inside of, if the groove is broken then replace the housing but if its good then all you need is the gasket, you will need to ask for thermostat housing gasket to engine intake, this gets confusing to a parts person as they may think you are asking for the thermostat gasket, also in the rear bottom of the housing theres a hose connected to the housing make sure thats not your leak, the hose may also be leaking. good day

Car overheats.....even just idling and no heat coming inside, is there anything special i need to change thermostat?... and where is it located?

No, Just a ratchet and socket set, flat tip screwdriver, pair of pliers, thermostat, gasket scraper,hose clamps, and gasket sealant(if you want to use it). Question for you: How old are your hoses? 3 years or older? If so, might as well change them also. Remove the top hose( helps to have it all out of the way), Its metric, about a #12 or #13 socket to remove the bolts holding the thermostat housing cover off. Remove that (STOP) turn it over and clean it down to metal (want no leaks), remove the old thermostat, (STOP) and lets clean the block also (no leaks) down to metal. Replace the thermostat, apply a think coat of sealant, place the gasket, on the housing, apply a thin coat of sealant. Replace the housing. bolt back down, and replace the hose ( always use new clamps, safety first). Let is sit about 30 minutes, allow the sealant to set, start the car let it warm up, and then top off the radiator. (adding fluid when the engine is hot, will put it to the correct level. Hope this helps.

How difficult is it to change a thermostat in a 2002 Ford Focus?

The Thermostat Housing is located on the right hand side of the engine. Remember this is FWD configuration so think of it as being mounted on the "rear" of the engine in terms of normal V6, V8, L6, etc.

Trace the radiator hose (right side of radiatoras you are looking from the front of the engine) and you will find it leads to the "water outlet" on the thermostat housing. There are a total of 4 hoses attached to the Thermostat Housing. It is a black plastic (OEM) housing held onto the engine by 3 bolts. Note: ther are 3 Torx screws visible, they for the water outlet housing and can be worked on while the Thermostat Housing is off of the engine. Plastic can easily crack/score so be gentle whe removing the hoses and hardware.

This housing is notorious for leaking even when a new gasket (O-Ring) is installed. I suggest dressing the housing mount surface with a small bead of grey RTV along with a new gasket prior to installing. Be sure to use only a small bead in an effort not to get excess into the housing or to foul the gasket.

My 2004 yukon denali only heats up once i start driving, and starts to blow cold air when i stop or it idles. thinking it may need a new thermostat

Yes, it sounds like your thermostat is stuck in the open position.

Your thermostat is located under a metal housing on the top of the engine. The upper radiator hose connects to this housing. To change the thermostat you basically need to drain the radiator after your engine is cold, disconnect the upper radiator hose from the engine, and remove the bolts from the small housing. replace the thermostat, and clean the surfaces on both sides and replace the gasket too. reinstall the housing, attach the hose, and refill the radiator. start the engine, warm it up and check for leaks, then re check the coolant level after the engine cools off again

Replacing thermostat

Follow the top radiator hose to the engine. The hose is connected to a metal housing, and the thermostat is beneath the housing. Remove the housing (not the hose) from the engine (2 bolts), remove the old thermostat and gasket (scrape the old gasket off if necessary), insert the new gasket and thermostat, and replace the housing.

Car is oerheating boiling out of the spillout valve

Follow your top radiator hose to the engine. Just before the engine you'll see a metal housing with a series of bolts in it that the hose is clamped to. Drain your coolant below this level (you can remove your lower radiator hose or remove the splash shield and use the draincock) and undo the hose, then remove the bolts in the housing. Remove the front part of the housing and clean the gasket material from the mating surfaces. To replace, buy a thermostat from Autozone with a jiggle valve (a little piece of metal in the top that jiggles)- this will aide in orientation upon reinstallation. Make sure you either buy RTV sealant to make a gasket, or a gasket (the gasket will probably be cheaper). Use the piece of the housing that is removable from the engine to twist the thermostat until it fits within the cut-out (the thermostat and cut out are not perfectly round). You can use spray adhesive on the gasket to aid in placement on the piece of thermostat housing that is connected to the engine. Replace thermostat with the spring side facing engine and capped side facing the radiator. Tight bolts, fill coolant and bleed.

On the '02 Mountaineer, 4.0L 6 cyl, does the o-ring gasket go into the thermostat housing before or after the thermostat? Instructions I've found are vague and I cannot find a diagram of the housing...

The O-ring gets placed on top of the thermostat. Ford uses a two-piece hard plastic housing (non metal) and if you insert the O-ring before the thermostat then it will leak. That leak might cause some to over-tighten the bolts holding the housing together and leading to cracking of the housing. (The upper housing costs about $45 and lower about $65.) There is no gasket between the two housings.The thermostat is designed to allow the O-ring to fit snugly.

Changing the thermostat on this engine is very easy. It's only necessary to drain a small amount of coolant from the engine to start the repair.

You're going to lose some coolant, so have a bucket or other container ready. Follow the upper radiator hose to the point where it's connected to the engine. The hose is clamped to a metal housing which is bolted to the engine. Remove the bolts (not the hose) and lift the housing to expose the thermostat (may require a little prying with a screwdriver or similar tool). Note how the old thermostat is fitted (which end is up), lift it out of the engine, and then remove all traces of gasket from the housing and the engine. Install the new thermostat and gasket, replace the bolts, add coolant as necessary, and you're done.

Bad thermostat on 2004 F350 Diesel 6.0

Drain the coolant out and remove the thermostat housing from the top of the engine - where the top radiator hose meets the domed cover on the top of the engine. Note how the thermostat is situated and replace the new one facing the same way. You will need to remove all of the old gasket material using a plastic scraper so you don't scar the metal and create a leak. Make sure the gasket pieces don't fall into the engine opening. (stuff an old rag in the hole). The parts store will tell you how to put the new gasket in and whether you should use RTV sealant or not. If you need RTV, use just a little. Put the gasket and thermostat in, put the housing over them and tighten the bolts by cinching one then the other until they begin to get tight. You are working with pot metal and aluminum so don't get too aggressive in making them tight. Replace the top hose if you disconnected it, refill with 50/50 coolant and antifreeze and run the engine to normal operating temp and look for leaks. If you find one, let the engine cool and try tightening the bolts a bit more. Make sure that the hose clamp is good and tight too.
