** How to Tell if You Need an EGR Valve **

Edited by Anthony Morgan, Maluniu, Teresa

Cars with Exhaust Gas Recirculation (EGR) valves help to reduce nitrous
oxide emissions. However, a faulty or defective EGR will cause motor to
shake, poor emissions, lack of power and stalling in extreme situations.
The EGR is an expensive component. Cleaning a stuck EGR valve will save you
money and is easy to complete.

* Steps *

1. 1
*Locate the EGR unit in the engine compartment.* It is usually located on
the top or side of the intake manifold and secured by 2 or 3 bolts
depending on the make and model of vehicle.

2. 2
*If your EGR is obscured by another component, you will need to remove that
component from the car to gain access to the EGR unit.*
3. 3
*Remove the negative battery cable.* This is a safety measure and will also
ensure that you do not accidentally short-circuit a component while working
on your car.
4. 4
*Remove the electrical connection from the EGR.*
5. 5
*Remove the bolts holding it to the manifold.*
6. 6
*Inspect the gasket for any damage or cracks, replace it if necessary
before re-installing the EGR.*
