Hello I will help you with your question,
Just to make sure we are talking about the same part look at this diagram. There are no fuel lines that I am aware of to change this valve but it might be possible to install it backwards so check the orientation of the original.
The nut for the lines is a 10 mm nut but that is on the front of the engine I believe
Here is the service information to change the valve
- Disconnect the electrical connector from the solenoid.
- Remove the two mounting bolts from the base of the EGR valve.
- Remove the EGR Valve.
- Inspect the EGR passages in the crossover water pump housing for deposits.
- Clean the EGR passages as needed.
- Clean the mounting surface for the EGR valve.
- Install cleaned or replacement EGR valve using a new gasket.
- Install the two mounting bolts at base of EGR valve. Tighten the 2 mounting bolts to 24 Nm (18 lb ft).
- Connect the electrical connector to EGR solenoid
You can try cleaning the valve first, its worth a shot
EGR Valve Cleaning
Whenever the EGR valve is removed, or during regularly scheduled EGR system maintenance, the EGR system should be inspected and cleaned. This will insure that the EGR system will function properly under all operating conditions. Proper EGR system service consists of the five steps listed below:
Caution: When removing components for cleaning, avoid breathing fumes and swallowing EGR exhaust deposits as bodily injury may result.
EGR System Service
- EGR System Diagnosis. Diagnosis of the EGR system should be performed if required by engine performance or engine driveability symptoms and no PCM DTCs are set.
- EGR Valve Pipe Cleaning and checking for leaks. Clean and check the EGR pipe from the exhaust manifold to the EGR valve and the EGR pipe from the water pump crossover to the throttle body spacer.
- EGR Valve Cleaning. If the EGR system is operating correctly, the EGR valve can be removed, checked for deposits, cleaned, and replaced. Use the procedure below for this operation.
|3.1.||Remove the EGR valve from the engine.|
|3.2.||While holding the EGR valve in your hand, using a pencil eraser or other suitable soft instrument to depress the pintle several times. The pintle should move in and out smoothly, replace any valve that exhibits tendencies to stick.|
|3.3.||While holding the EGR valve base in your hand, try to rotate the connector housing. Repeat for the coil housing. Replace any valve that exhibits looseness.|
|3.4.||Inspect the EGR valve pintle and seat for deposits. Use a cloth or other suitable soft device to remove deposits. Remove all loose particles. If deposits are such that pintle/base interface can't be cleaned adequately to allow pintle to seal against the seat, replace the valve. Damage to the powdered metal EGR valve base will occur if cleaned with solvents, sharp tools, wire brush/wheel or sand blasting. Cleaning by these methods is not recommended.|
|3.5.||Inspect the passage in the Crossover Water Pump Housing for deposits. Remove all loose particles.|
|3.6.||Replace EGR valve on engine, using a new gasket.|
- EGR Passages in Crossover Water pump Housing.
|4.1.||Remove Crossover Water pump Housing.|
|4.2.||Remove 2 plugs (2) and clean passages with a wire brush. Remove all loose particles.|
|4.3.||Put Crossover Water pump Housing back on engine.|
- Wash-up after any contact with deposits from the EGR System.
The best part of that is to test the pintle for free movement
