- 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.....
- You can also get a good bit of the air out by removing one end of the upper radiator hose from the car and filling it with antifreeze. I recently had a 93 Civic in my shop that DID have a bleeder valve on it. If your car does the person above gave you the correct method of bleeding it.
- Q: We need to replace our erg valve, but we cannot locate it.
- i'm no longer attentive to that style. some cam sensors are on the front of the engine. some are under the valve conceal. My advice could be, to call the save that offered you the sensor and ask them or call a dealership. in many cases they are satisfied to help. grasp tech 40 yrs.
- Q: what's the differences of American standard valve standard and Europe valve standard.Like API598 and ISO5208 , EN12266 valve inspection standard, or API600 valve design manufacture standard,and EN598,
- It is hard to say generally. Each valve standard will cite other relevant standards, so it is API system and ISO system. Usually it has some differences between API and ISO valve, but it is similar. Most time the design Principal is same, the structure of valve is similar. For example , API swing check valve, it has an hanging system without bolt outside of body, but DIN swing check valve has an bolt for stem. The dimension obviously is different, API calculated by inch, but ISO usually use metric unit. Of course it can be transformed to same dimension. Below is some API standard, and ISO or DIN Standard. We are just able to discuss this topic for specific standard. For API598 and ISO 5208, in my opinion, it is a little different, but in fact, the differences is not very big, if an valve able to pass API598, usually same for ISO 5208. Same for ISO5208 to API 598.
- Q: Can a dirty or faulty EGR valve cause overheating. My 2001 PT Cruiser is overheating but only on very hot days and when the air conditioning is on. Back flushed and pressure tested the radiator, changed the thermometer, fluid was low but doesn't seem to be loosing fluid since refilled. Check engine light came on and indicated poor air flow through the EGR valve. Is it worth replacing prior to pulling the radiator to check that for the problem with overheating? Mechanic I trust doesn't think the EGR can cause overheating.
- This people above do not know much about EGR's which one of the main purposes is to lower combustion temperatures by introducing exhaust fumes into the intake. So yes it can add to the overheating problem. source GM tech
- Q: does it moves up and down with the valve stem??
- Poppet valve is the commonly used term for a standard, mushroom- shaped engine valve.Obviously, the mushroom head is part of the valve, so yes, it does move up and down with its stem.
- Q: hi guys..What is different between globe valve and stop check globe? Is that stop check globe=SDNR JIS std?
- I am not even sure what you are talking about. a globe valve is a type of valve that can stop the flow by turn a handel on top of the valve. A check valve on let the flow go one way and stops the flow the other way. hope this help Globe valve From Wikipedia, the free encyclopedia Jump to: navigation, search A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.[1] Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug[2] can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.[3][4][5] In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel. Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.
- Q: If this prolapse considered heart disease. I was diagnosed years ago with it . My doctor at the time told me this is not heart disease and now I googled it and it said this is heart disease. Another person said this is valve disease ? I never asked my current doctor if it was or not. She checks me every 3 months because I have a heart murmur that you can have with this prolapse. whenever I have filled out questionaires about health history when they ask me if I have heart disease I always check no. If this considered heart disease or valve disease. I've never been to a cardiologist for it. Should a person have at least one evaluation from a cardiologist for this ?
- Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.
- Q: I saw that they sell a kit to block off the egr valve in my dodge neon. Since this was on a performance site what will this do? Will blocking off the valve give me more horsepower? Should I do it or not? Thanks
- The EGR valve only opens when there is hard excelleration.That can cut down very slightly on your power.Your fuel system is compensated for the slightly lean affect it gives when open.If it's working correctly, you will gain very little performance by blocking it. But just blocking it off, will help a little, you probubly you won't notice though.
- Q: I have a hot water oil burner. I need step by instructions on how to replace the pressure relief valve.Do you know?Please help me.
- Your precise, the priority could desire to have long previous away with the previous valve. Your new valve could be defective. in the previous you substitute it however there's a reliable probability your furnish rigidity is to extreme. it must be filling at a extreme rigidity to start with and then as quickly as heated it exceeds the shrink. This sounds like a greater sensible clarification and could greater healthful the priority. while you're hooked to a municipal water furnish they could be in possibility of pay the cost of having a ''rigidity regulator'' put in. or you will could desire to foot the bill.
- Q: I went look at a car, and the guy selling the car said that the engine valve is leaking. Is this a big deal? How urgent would it need to be fixed? How much would that cost?
- No, the valve cover can't cause that. You're check engine light is probably disabled by the same *** that cut your catalytic convertor off. Thanks for cutting off your cat a polluting so you can drive your stupid truck around. Screw everyone as long as you can go squirrel hunting or whatever you do in that truck. It's hard to say what's wrong with it because you have negated the computers ability to control the fuel flow properly. It could be the mass airflow sensor or maybe a stuck fuel injector. Even with the computer whacked, a real mechanic should be able to figure it out pretty quickly if he has the proper diagnostic equipment. You may want to just change the O2 sensor anyway as it probably hasn't been changed for quite a while.
