- Q: How do you clean an EGR valve on a 1999 Ford Taurus DOHC? What do I do and what can I use? Will water work? I've read a lot about a plunger mechanism but I have no idea what this is. Please explain in the best detail you can how to remove, clean, and re install the EGR valve?
- The egr valve doesnt get dirty on its own; if there is a problem with foreign material in it, its coming from the exhaust stream, not the valve. But if you need to clean it anyway, then just unbolt it, push in the valves plunger from the bottom, and pick out anything blocking the valve from closing. They do not plug up. Also, check to make sure the vapor holes where the valve bolts on are clean, they do plug up. the mechanics of it are pretty basic.
- Q: What are the names of the main arteries and valves?????????REALLY NEED ANSWERS TODAY!!!!!!!!!!!
- Main arteries: Aorta (oxygenated blood from heart to body), Pulmonary Artery (DEoxygenated blood from heart to lungs). Main Valves: Tricuspid valve (separated right atrium and ventricle to ensure correct flow of blood), Bicuspid Valve( separates left atrium and ventricle), Aortic Valve( ensures blood flow from left ventricle into aorta). hey sorry only saw ur question today:P hope it helps!
- Q: The water in my tub/shower stopped working. I did my research on the net to discover the cause and I also went to Home Depot explained the problem. The worker at home depot helped me get the right part I needed to replace the valve stem. I came home, took the faucet handle off and can see what I need to do next. Everything seems perfect and ready to go, except I can't remove the old valve stem. It seems like the old one should just slide out and the new one replaces it. How do I get the old one out without damaging any of the pipes or hurting myself.
- Do you have a valve for the hot and one for the cold, or does one valve control both? If there are two valves they should just unscrew. You might need to go back to Home Depot and get a wrench designed for valve stem removal. (Before you go, spray it with penetrating oil such as WD-40 and let it do it's thing while you're gone. If it's just one valve for both, there's probably a collar that screws on and holds the cartridge in place. After that is off, the cartridge should slide out-ususally with a little 'persuasion' from some pliers. (But don't try to twist it) Hope you get it.
- Q: Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.
- Valves make a ticking noise due to: -normal wear -faulty lifter -faulty valve spring
- Q: I own a 2001 Chevy cavalier Z24 with a dual cam... Just got it tuned up and noticed oil in my spark plug sockets, which leaves me to assume either the valve cover gaskets or the cam carrier gasket is leaking oil... I would prefer to so this by myself considering I'm sure it's going to be costly.. Anyone have any ideas on how I go about replacing either?
- valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
- Q: I just installed a iac valve on my 2001 blazer but didnt go through the reset steps. Do i have to unistall and do the steps or go from here with the reset. Truck stalls out now and surges... Or could i just hava a defective part.
- The okorder /
- Q: When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!
- it is a common cause of murmurs in children, and ordinarily they grow out of it, you can relax.
- Q: The valve on my radiator has numbers on it to determine the amount of air/steam leaving the heating system. what number should i put it on and how would i determine it
- I would think the easiest way would be to put a thermometer on the radiator (with the bulb in the air flow), turn the heat on to one setting and record the temperatures each half hour for about 4 hours. Then, turn the adjustment to a higher (or lower) number and repeat that. That way, you'd know which way to turn to set it. Of course, the level at which you'd be comfortable would be found by trying different settings. Assuming the adustment is a valve, valves in the USA will open by turning counter-clockwise. Closing is, of course, clockwise. Hope that helps. EDIT: I received your email - I don't mind at all! OK, so you have only one valve for all the radiators. Without knowing anything else, I'd say you just removed the part called the bonnet (the upper half of a valve). It shouldn't matter which number it's set on if it's reinstalled correctly. When a valve is removed, the best way to put back is to open it slightly (turn counterclockwise to a low number), then reinstall the bonnet. Once it's back in, it should work like normal. If that doesn't work, perhaps you can get a plumber or a local handyman to check it. As to the upper ones being airlocked, it really sounds like there is a blockage in the supply line. I am assuming this is steam-heat radiator that is supplied by a boiler-type heating unit?
- Q: I've never replaced a shut off valve before but am wondering if there are any tricks in freeing up a stuck valve that wont close. Can this be done so I don't have to call anybody?
- turn off water to house, if your valve has a nut behind handle that has threads on inside of nut ie brasscraft style, you can go to store and buy new valve and replace stem. If pipe comes out of wall (angle stop) get that one, if comes out of floor (straight stop) get that one. remove new stem and old stem and switch. If nut behind handle has threads on outside of nut, then you must replace valve. ( you have to remove nut to see where threads are ( i don't but you might) depending on what type of pipe you have is what new valve you will need and also how close to wall or floor is how to attack problem tre..706yahoo 4 any more help
- Q: I have a 97 ranger 4.0L that takes 10w-30 and I'm going to be changing the oil soon. It has some valve clatter I'm just wondering if I can use a thicker oil such as 15w-30 or maybe a 10w40?
- I wouldn't go any thicker than 10w-40. I have seen 20w-50 in the parts stores, but this will put a lot of strain on the oil pump. You may regret it down the road, and it's just a little bit of noise. Good luck.
