Pontiac Grand Prix PCV Valve

The PCV Valve in Pontiac Grand Prix vehicles plays the important role of regulating emission and improving engine performance. Since the PCV Valve recirculates the combustion byproduct gases back to the combustion chambers, there is maximum burning of the gases, thus curtailing on emissions. Depending on the conditions of the intake manifold vacuum, PCV Valve closes the gas flow during idling time and opens it during the load to help in ventilating crankcase gas without any hindrance on the operation of an engine. Moreover, the PCV Valve also serve as a flame arrester and help in ensuring good draw through by preventing the positive pressure from entering the crank case. Therefore, maintenance of the PCV Valve is critical to its proper functioning avoiding accumulation of contaminated engine oil, leakage and other complications that may cause PCV Valve to be replaced.

Each OEM Pontiac Grand Prix PCV 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.
