How to Maintain the Downstream Oxygen Sensor on Chrysler 300M?

Don't start work yet on the downstream O2 sensor, since the hot exhaust system can burn you if it is not cooled first. First, remove the negative battery cable then jack up the vehicle and support it. Remove the wire connector from the O2 sensors and try not to pull the wire going into the sensor. Remove the Snap-On oxygen sensor wrench (number YA 8875) to remove the O2 sensors. For installation, understand that the new oxygen sensors are coated in anti-seize compound by the manufacturer, so an extra coating isn't needed. Fit the O2 sensor and tighten it to a torque of 28 N.m (20 ft.lbs.), after that plug in the O2 sensor wire plug. When sure of the wiring, drop the car, hand insert the negative battery terminal and then tighten the cable.

How to Replace an Engine's Oxygen Sensor on Chrysler 300M?

Oxygen sensors are mounted in the outlet flange of the exhaust manifold and the engine is equipped with two such upstream heated sensors. Before you install a new oxygen sensor, wait until the engine has cooled down, since the exhaust manifold, exhaust pipes and catalytic converter get extremely hot while the engine is running. Release the negative battery cable and disconnect the hidden oxygen sensor electrical connection, not directly pulling on the wire. Remove the oxygen sensor using Snap-On YA8875 or a crow's foot wrench. Following removal, use an 18 mm X 1.5 + 6E tap to clean the exhaust manifold threads. If the original sensor is used, grease the threads first using Loctite 771-64; sensors that are new are pre-greased and require no additional product. After tightening the sensor to 28 Nm (20 ft. lbs.), attach its electrical connector again, then link the negative battery cable up again.

Oxygen Sensor is an important part that greatly increases effectiveness and durability of Chrysler 300M automobiles. Being an element of accurate transmission, this Oxygen Sensor is used to determine the amount of unburned oxygen in exhaust gas to maintain optimum air-fuel mixture and reduce pollution. Since the Oxygen Sensor produces a voltage signal in proportion to the amount of oxygen, the engine control computer is able to make changes to the fuel injector pulse width and monitor the vehicle's performance in a distinguished "closed-loop" fashion. Usually, the Chrysler 300M models are equipped with zirconium dioxide-based technology; there are upstream sensors that give instant feedback for air-fuel ratio regulation, and downstream sensors that analyze the catalytic converter status. This two-fold allows for improvement of fuel economy and is also a safety factor that helps diminish emissions. The Oxygen Sensor is suitable for a number of 300M models; thereby, enabling drivers to break the benefits of efficient engine operations across the board. Some of them include air/fuel ratio sensors that are installed in the new models apart from a broad measurement range and higher accuracy as opposed to the traditional Oxygen Sensors; all these make the Oxygen Sensor to stand out in the marketplace. In conclusion, this product guarantee's the reliability and performance of the Oxygen Sensor as a vital part for any Chrysler 300M owner seeking to preserve the car's performance and safety.
