I have a 2007 chrysler 300c 5.7 engine. I am trying to replace the egr valve.. I have removed 3 bolts but am having a hard time removing the bolt closest to the alternator...

Hi thanks for your question' The electronic EGR valve and solenoid assembly is attached to the rear of the left cylinder head ,

1. Remove electrical connector (5) at top of EGR valve solenoid.
2. Remove tube mounting bolt (1) at intake manifold.

1. Remove two bolts (4) connecting EGR tube (1) to valve assembly.
2. Remove gasket located between EGR tube flange and EGR valve assembly.
3. Remove two EGR valve mounting bolts (5).
4. Separate valve assembly (3) from engine.
5. Remove and discard metal gasket located between cylinder head and valve assembly.

Exhaust Gas Recirculation (EGR) System The exhaust gas recirculation (EGR) system is designed to:

• reintroduce exhaust gas into the combustion cycle.
• lower combustion temperatures.
• reduce the formation of oxides or nitrogen (NOX).

The amount of exhaust gas reintroduced and the timing of the cycle varies by calibration. Timing and volume are controlled by the following:

• engine rpm
• engine vacuum
• exhaust system back pressure
• engine coolant temperature
• air charge temperature
• throttle position

The EGR valve (EGR valve) (9D475) is vacuum-actuated. The vacuum hose routing diagram is shown on the Vehicle Emission Control Information (VECI) decal. The EGR system is a differential pressure feedback EGR Sensor system. Differential pressure feedback EGR Sensor is a subsonic closed loop EGR system. The differential pressure feedback EGR system:

• monitors EGR flow rate by the pressure drop across the metering orifice located in the EGR tube.
• uses a differential pressure feedback EGR sensor as the feedback device.
• uses the EGR valve only as a pressure regulator, rather than a flow metering device.
• controlled pressure is varied by the valve movement using vacuum output of the EGR vacuum regulator solenoid (9J459).
• allows for a more accurate assessment of EGR flow requirements.

Hope this helps

Sounds like you have a carbon buildup in the valve. The EGR should be located near the altenator on the right side of the engine, depending on what engine you have. 4 bolts, 2 8mm and 2 10mm.. take it off and careful not to lose the metal gaskets.. spray the valve down with carb cleaner and wipe it out.. pump the valve to make sure it plunges ok and replace. should fix your problem. Or you can replace the valve yourself new for about $80.
Here is the procedure if you care to do it yourself.

Tools: 8 mm socket, 10 mm socketEquipment: Replacement EGR Valve, Replacement EGR Gasket (metallic)1. Disconnect the electrical fitting attached to the EGR valve. You will need to unlock it (red tab) and then depress the latch near the rear of the fitting before sliding it off.2. Disconnect the vacuum tube connected to the top of the EGR valve using an 8 mm socket. It may be easier to remove the entire vacuum tube by diconnected it at the top of the engine as well (also 8 mm).3. Using a universal socket joint (I found using a 1/4" drive was necessary to get the clearances around the alternator), remove the 2 bolts holding the EGR valves to the exhaust manifold of the engine using a 10 mm socket. The bottom bolt is a very tight clearance.4. Remove the valve and gasket.5. To install, reverse the steps using the new EGR Valve and EGR Gasket.6. The 10 mm bolts should be torqued to 225 in-lbs7. The 8 mm bolts that fasten the vacuum tube to the EGR valve should be torqued to 100 in-lbs.
Tip: I have found that if you loosen the alternator mounting bolts, you can get just a little more wiggle room to get a socket on the bottom bolt.

Good luck, i hope this helps, please rate me a fixya.

The EGR valve is usually not servicable. Just replace it. it works in an ugly environment.

P0404 IS EGR POSITION SENSOR PERFORMANCE..YOU NEED A NEW EGR VALVE..RECOMMEND DISCONNECTING BATTERY WHILE REPLACING EGR VALVE..SOMETIMES CODE WILL NOT GO AWAY EVEN AFTER REPLACING VALVE AND CLEARING CODE WITH SCANNER..VALVE IS LOCATED ABOVE ALTERNATOR ON END OF CYLINDER HEAD..THE BOTTOM BOLT CAN BE TRICKY TO REMOVE AND HAVE HAD TO REMOVE ALTERNATOR TO GET BOLT OUT..YOU WILL NEED A NEW GASKET FOR TUBE AS WELL..ABOUT 120 BUCKS FROM DEALER(CAN)

if this is a 4.7l engine, the valve is on the left rear of the intake. loosen the 8mm bolts that hold the egr intake tube to the egr valve, remove the egr bolts, disconnect wiring, remove valve and tube together, attach intake tube loosely to new valve, install new valve, tighten tube bolts to egr using a swivel socket, this is not a 5 minute job, so dont attempt unless you have some time and patience.

Found the info!!

This Dodge EGR valve is a certain kind of device that is mounted right on your intake manifold which controls the amount of exhaust gasses back into your engine.
On a 2005 Dakota with 4.7 liter engine (non-HO), the EGR valve is located near the intake manifold on the driver's side right up against the firewall. It's hard to spot as it sits lower than the intake manifold. To change it, remove the electrical connector. There's a red tab that needs to be pushed to one side and then you have to squeeze down on a tab to get it free. Using a 13 mm socket, remove the bolt that you can see. I had to use a 3 inch wobble extention and then a 8 inch extension with a deep well socket to reach it with my 3/8 inch ratchet. There's a second bolt that you can't see between the EGR valve and the firewall. With a little trial and error and a lot more luck, you can reach the hidden bolt with the 3 inch wobble extension and a 13 mm deep well socket. Attach the ratchet after the socket is on and remove. This one isn't easy and if there's any Dodge engineers reading this one, a couple of extra inches of clearance between the valve and the firewall wouldn't have killed you no matter what the cost accountants said. With both bolts removed, you should be able to pull out the metal pipe that connects the manifold to the EGR valve out of the manifold (Pull to the right) and then you can lift the valve out. For assembly, the metal pipe connecting the intake manifold the EGR valve has to be removed and reinstalled on the new valve. It's held on with 2 5/16th" bolts. You should put the rear bolt on tight, but leave the front bold loose for the reinstall as some adjustment is necessary to get it put back together and the rear is a pain to tighten when installed. Line up the bolts that attach the valve and get the rear 13 mm bolt (The one you couldn't see on disassembly) started. Do not start the other 13 mm bolt as you'll need to pivot the valve and pipe to the left in order to reinsert the pipe into the intake manifold. Once the pipe is in the intake manifold. Start the other 13 mm bolt and tighten both 13 mm bolts and then the 5/16" bolts holding the pipe onto the valve. Reinstall the electrical connection. Please don't forget to rate!!!!
