EGR Systems
When the temperature in the combustion chamber becomes extremely hot, nitrous oxides are formed, which then turn into smog. In order to reduce such occurrence, the exhaust gas recirculation system minimizes the temperature in the combustion chamber.

How do you do an ERG valve clean out on a 2001 Ford F-150?
4.2L, 4.6L, 5.4L and 6.8L Engines 1. Disconnect the negative battery cable. 2. Remove the vacuum hose from the EGR valve. 3. On the 4.6L engine, remove the nut and brake booster bracket. 4. On the 5.4L engine, remove the DPFE sensor retaining nuts and place the sensor to the side to allow access to the EGR tube. 5. Disconnect the EGR valve-to-exhaust manifold tube from the EGR valve. 6. Remove the EGR valve mounting bolts, then separate the valve from the intake manifold. 7. Remove and discard the old EGR valve gasket, and clean the gasket mating surfaces on the valve and the intake manifold. To Install: 8. Install the EGR valve, along with a new gasket, on the manifold, then install and tighten the mounting bolts. 9. Connect the EGR valve-to-exhaust manifold tube to the valve, then tighten the tube nut to 25-35 lbs. (34-47 Nm). 10. Connect the vacuum hose to the EGR valve. 11. On the 5.7L engine, install the DPFE sensor. 12. On the 4.6L engine install the brake booster bracket and the retaining nut. 13. Connect the negative battery cable.
Where is the 02 sensor located on a 1996 Chevy silverado?
my 96 with 5.7 ltr has 4 of them, 1 located by the exaughst manifold on each side, and also 1 located on each side by the converter
The egr is located on the front cylinder head where the belts are located, it has a five wire connector an a tube that goes to the intake pleneum.
Early 2004 egr's were vacuum and later ones were all electric.
How do you clean egr ports on a 2001 v8 4.6l expedition?
Sorry, I'm looking for the same answer. I just brought my 2001 Ford Expedition 4.6L V8 to the shop because the Check Engine Soon Lights is on. I paid $73 dollars. They told me my EGR Valve need replacing and the EGR ports need cleaning. Estimated price $600.00. So if anyone can tell us this I would and my wallet would be very greatful..
Where is the EGR valve located on a 1991 Geo Prism 1.6?
Underneath the intake manifold, it bolts on at cylinder # 4. or first from the drivers side. It is found right under the EGR Modulator. Disc like device with two vacuum line on the pasenger side and one vacuum line on the driver side. Best way to get to it is to remove the intake manifold.
Where are the idle air control valve and the EGR valve on a 1993 Chevy 1500?
It is on the left side of the TBI Throttle body, and it screews into the side of it.
with a electric connector plug on it. ( Idle speed control)
The EGR valve is on the lrft side of the intake manifold, close to the valve cover.
Will car run with disconnected egr valve?
If you mean disconnecting the electrical leads, Absolutely. If vacuum actuated, you'll have to plug off the active (sucking) end of the hose. If your egr is stuck it will probably run better. You will get a check engine light and won't pass emissions though...
Trouble code P0401 means: Exhaust Gas Recirculation Flow Insufficient Detected
Where is the exhaust gas recirculation valve EGR located on a 97 s10 Chevy blazer 43L AC v6?
It should be on the front of the intake manifold directly above and behind the water pump.
Where is a 1995 Firebirds egr located?

Where is the thermostat and EGR valve on a 1991 Silverado?
The thermstat is in the housing at the motor end of the upper rad hose. Two bolts hold it on. The EGR is on top of the intake manifold near the throttle body. It has a vacuum hose and two bolts. If I remember correctly the bolt are inverted torks. Which require a special tool to remove. Use a pair of locking plyers to remove, then replace bolts with standard ones.
Where is the egr valve located on the 2005 Chrysler 300c?
Passenger side, front of engine, just above the alternator.
What causes black sooty exhaust?
What can cause black sooty exhaust is bad valve guides. When the guides are bad oil leaks into the cylinder when the car isn't running. When the car starts it produces black exhaust.
Where is the egr valve on a 1997 ford ranger?
Start at the exhaust. Look for a pipe that goes to the intake. There will be a valve with a vaccuum tube, this is the EGR valve The EGR valve returns exhaust to reduce N.O. At idle it is closed, at 55 rpm it opens. You can test the part to see if it holds a vaccuum, otherwise that's about all it does. Most of the newer cars will also have a solenoid switch. Now this switch must be tested for ohms and if open will cause problems at smog test. A bad solenoid will cause a "fail"
Why is there a hesitation as you apply the accelerator?
A defective EGR Valve will cause hesitation on acceleration.
Does a 2000 pontiac gran am 4 cyl. Have an egr valve all that parts stores have is a gasket. Gm says it does not have one. Car shakes and shimmies when you stop at an intersection which everyone says check the EGR valve
How do you replace the EGR valve on a 2001 Ford Expedition and where is it located?
I may be able to offer some help. I have just replaced the EGR Valve on a 2002 expedition with the 4.6 engine. If the motors are the same from 01-02 here's your answer. The EGR Valve is located on the driver side of the motor. It is all the way at the rear of the motor near the firewall. The valve has a circular top with a vacuum hose attached. there is an outlet/inlet pipe below the top. There is a metal hose attached to the outlet/inlet. This hose runs up from the exhaust. I started by removing the plastic shroud from the top of the motor. Then I removed the nut on the rear bolt of the assembly to move the hose support out of the way. Next, I removed the rear bolt. Leave the front bolt in place for now. There is a nut on the top of the metal hose that comes up from the exhaust. Loosen this nut and remove the metal hose from the bottom of the valve. Now remove the forward bolt. Here is where I apparently missed a step. After replacing the valve I cleared the trouble code. The service engine light soon came back on. After speaking to some mechanic friends I was told I should have removed the metal hose and cleaned out the carbon or at least have run a pipe cleaner through it. NOTE: I purchased the replacement EGR Valve directly from Ford. I was given the wrong part. The parts guy said it was an error on their catalog. I suggest you take your old valve to the parts counter with you to avoid this problem.
I'm not a mechanic but this is how I got it done. Maybe others can give you better advice.
I had the same problem with my 1999 Expedition so we removed the EGR valve and cleaned out all the carbin and reinstalled EGR valve Undo the batt for about 10 min. to clear computer
