Pontiac G6 EGR Valve
In Pontiac G6 vehicles, the EGR Valve is used to control the circulation of exhaust gases back to the combustion chamber, and therefore reducing the emission of air pollutants whenever the air-fuel mixture is sub-standard. This system is to reduce nitrogen oxide (NOx) emission by using a part of exhaust gases, which contribute to the reduction of combustion temperature and to the enhancement of the engine performance. Various types of EGR Valves have been incorporated in Pontiac G6 models from only a simple orifice jet to sophisticated valves that operate on the signals derived from the engine such as the coolant temperature and manifold vacuum. The contemporary EGR systems can include backpressure transducers to adjust flow according to realized load. Although they are useful to reduce the emission, EGR Valges in Pontiac G6 cars tend to be clogged with carbon, thus need occasional servicing.
Each OEM Pontiac G6 EGR Valve we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Pontiac G6 EGR Valve Parts Questions & Experts Answers
- Q: How Does the EGR System Reduce NOx Emissions and How Do You Replace the EGR Valve and Pipe on Pontiac G6?A: Nitrogen oxides or NOx are products of combustion chamber and are formed from the combination of oxygen and nitrogen from incoming air particularly at temperature rise of 2500 degrees F and above NOx when emitted out in the tail pipe react with reactive organic compounds, hydrocarbons, and sunlight to from H2O and photochemical smog with contribution to forming O3. EGR is a method of reducing nitric oxides by circulating exhaust back into the cylinders causing, dilution and cooler burn. These concern the 2008 and earlier 3.5L V6 engines as the four cylinders do not employ an EGR system. The EGR system is evaluated by the Powertrain Control Module along with the EGR Valve and other sensors that factor its intrinsic working. Energising the solenoid effectively opens the EGR valve by lifting the pintle which permits the passage of exhaust gas from exhaust manifold to the intake manifold when the control module short circuits the power supply to the EGR valve through a transistor. The EGR valve utilizes a position feedback circuit also to take care of the pintle position - a sensor checks the position so that the EGR maintains the right status. High flow of EGR causes stalling of the engine, or rough idle while low flow can cause high combustion temperatures which can lead to spark knock or overheating. To remove the EGR valve, one needs to detach the electrical connector, remove the securing bolt and the mounting bolts, and preceded to clean the mating surfaces before installing a new gasket before reinstalling the bolts and connector in reverse order. In EGR pipe replacement, you need to take out the upper flange bolt of the EGR valve, and the lower flange bolts of the exhaust manifold, clean the pipe and then re-install it after making sure that the threads of the mounting flange bolts have been coated with anti-seize compound.
