Q: Ok so I have a Honda Civic 97 lx and what happened was that when I did an oil change the next day the car started over heating, the car only had pure water and no coolant, the over heating part happened during noon when I was driving on the freeway the next day and not the night I made the oil change... After that I decided to put 50/50 coolant but the car still over heats, a friend told me that I probably needed to do a coolant system bleed, I try to do it but I couldn't find the bleeding valve or bleed screw... can anyone pls tell me where that valve or screw is located, I discovered a sort of valve that is covered by a black rubber cap , its next to the engine I don't know if that's what I'm looking for.....: Your car does not have a coolant system bleeder valve built in. Most of the time you would bleed it using the coolant temp sensor as your bleeder. Remove it with the engine cold and start the car. As soon as a steady stream of liquid (without bubbles/air pockets) becomes visible, quickly thread the coolant temp sensor back in and snug it down. Shut the car and top off the coolant reservoir and your done. Good luck!

Q: so do v-6 engines mean 6 cylinders right?, but what are valves? sometimes they are like double the cylinders (12 valve v6). what do they do, and cars that have like 2.5L does that mean how much fuel is injected and does more mean more power?on a side note, what kind of engine is the evo x? is it 4 cylinder? but has really good technology in it and is that how it has such high bhp?also if anyone knows, i kinda know what torque is but can someone explain in laymen terms? does more=better?: Yes v6 means 6 cylinders (pistons). Each pistons need to have gas come in and out and so the valves open and close to do exactly that (breath). There are at least 2 valves per piston - one (set) for exhaust and another for intake. Sometime to make it breath easier, there are 2 valves on each set. The 2.5L mean 2.5 liters (the measurement of the pistons) or basically the engine. The larger the displacement the more powerful (theoretically). Of course the larger the displacement the more fuel need to be injected. The exception is TURBO charged engines which stuff extra air (and extra fuel) so even a small engine take more fuel than equal non-turbo engie. The Evo uses much more than high tech engine to be that good. Besides being powerful, it uses the computer to divide the power to all 4 wheels in such a way to keep the car pulling even in a hard turn. === The TORQUE is the actual measure of engine power. The horse power is a translation of torque into something that people understand (horse - power). Good Luck...

Q: Glob Valve or Gate Valve: Sea Chest Valve

Q: HowdyWas taking apart a screw down NR valve and screw lift valve and noticed the spindles were made out of different materials. Brass and Steel.I am aware that brass is non corrosive but why use steel in the other valve? Is it due to their operation, do they come or not come in contact with fluids? Is one cheaper than the other?The screw lift globe valve had a steel spindle and the screw down nr glove valve had a brass spindle.Also, if anyone knows what materials are used in the valve lid and seat are made of.Any ideas?Cheers: Brass is used in some cases because it it less likely to corrode. It is used in other cases because it is softer than steel and can act as a bearing surface. Steel is usually used because of its strength relative to brass. In some cases they are used in combination so the steel surface and the brass surfaces compliment each other to provide a smooth sliding surface. Bronze is also a popular material for some valves and parts of other valves. Usually in water or steam service. Many times the valve seats are made from a harder material such as stellite. See site below for more info on stellite.

Q: I somehow lost the valve cap to one of my tires. Do stores sell replacement caps? If so, would a place like Sears or VIP be a good place to look? If not, would a bike tire valve cap work?In the mean time, i took a cap off the fullest tire to put on this one(the lowest) was that good or bad idea?: Tire Caps For Cars

Q: The Hawker Tempest was the fastest piston powered airplane ever made, it had a sleeve valve engine. It was made obsolete, by the Me 262 and other jet engined fighters, But it's engine was the ultimate piston aircraft engine. Then piston engines became something for inexpensive planes, but why has the sleeve valve not undergone further development as a sports car engine?: i like to call them the two creation memories of Genesis the 1st tale which starts Genesis a million and ends Genesis 2:3 the 2d tale starts with Genesis 2:4 and keeps onward. on the tip of Genesis a million:27 it states that God created the two guy and lady which gave upward thrust to the perception that guy and lady have been created on an identical time interior an identical way wherein the guy replaced into Adam and since the story is going the female replaced into Lilith. yet of direction you will desire to comprehend that the Lilith tale is basically that a narrative in fact the Hebrews did no longer even supply her a acceptance the call originated latter on however the Lilith tale is folklore. The Lilith tale began for the period of the Babylonian exile of the Jews in spite of the undeniable fact that it would evolve for the period of the middle an prolonged time in Europe.

Q: I am trying to shut off the water valves under my sink to install a new kitchen faucet. The hand knobs appear to be damaged (thin soft metal). In addition, they seem to be seized up pretty well. So I can't shut them off by hand and not sure what I can use to close it off without damaging it further. My initial thought is to replace the valves. Any suggestions?: This is a common problem. Don't force/twist them or they could break off. You will need to shut of water to your house [assume it is a single family?] The shut off is frequently in the front of the house where the water enters and could be under a hose bib [outlet]. Don't confuse the water shut off handle with the water pressure regulator, a dome shaped metal cylinder attached to the incoming water pipe. If you can't find the shut off there is usually one on the water utility's side of the water meter - closest to the street or road and sometimes one just on the outlet side of the water meter that you can twist by hand. After shutting of the main water supply to the house relieve pressure at a low point - usually a hose outlet. This way when you remove the water supply valve under the sink you won't get a cascade of water. You may want to douse the shut off [sometimes called angle stops] with some penetrant like PB Blaster penetrant and let it sit. You may want to purchase 1/4 turn ball style shut off valves as opposed to the twist or gate style. Note the size inlet, IPS 1/2 inch, 3/4 etc. and the outlet size, generally 3/8' for new faucets. Take a photo with your phone or a digital camera and take it to the store when you purchase new shut off valves. If you have a dishwasher and the water supply goes to the hot valve, then be certain to get a shut off valve with two outlets and use it on the hot side. If you are in a condo or multi-family you will need their permission to shut off the water unless each unit has it's own shut off [more typical of town house style than apt style condos.]

Q: I want to switch off the water in the bathroom only due to replacing sink taps, will water still come out of the pipe if i turn the stop valve: Only water what is still in the pipes will come out but you will lose all your hot water in the hot water cistern if you have that type of hot water storage tank.

Q: The hot water in my bathroom is leaking from the faucet. I've shut off the valve below the sink, but it continues to dribble out. Also, there appears to be some rust build-up. Could that account for a failing valve?: It sounds like you have some lime build up in the valves if you can't shut them off or the rubber gaskets inside the valves are worn. Valves are made of brass which doesn't rust. only steel and iron rust. Try tightening the packing nut. That's the nut just below the shut off valve handle. If that doesn't work shut the warter off at the water heater and take the valve apart. First remove the handle from the stem with a screw driver, next remove the packing nut (usually 7/16) then put the handle back on a turn it counter clockwise. Inspent the valve stem, valve seat and the rubber gasket or washer for wear. If you see any lime build up (it will be a hard white substance) remove it with Lime Away or one of those brands. It the valve is very old you may have to replace it. If you own the house replace the valve with a quarter turn ball valve, They are more expensive, but will last a lot longer.
