How to Service the Heated Oxygen Sensors on Lincoln Town Car?

Initiate service of the Heated Oxygen Sensor (HO2S) by hoisting the vehicle into neutral gear position. First disconnect power from the right high HO2S electrical connector before removing the left high HO2S connectors. To remove sensors easily you should apply penetrating and lock lubricant on their threads followed by sensor disassembly. The Exhaust Gas Oxygen Sensor Socket is needed to take out the RH or LH HO2S based on requirements. The proper torque wrench mechanism must be determined for installation before securing the sensor with a 40 Nm (30 lb-ft) tightness. You should apply an anti-seize lubricating layer on HO2S threads after performing the removal operations in reverse order.

The service process for Heated Oxygen Sensor (HO2S) requires positioning the vehicle on a hoist at neutral. Remove the HO2S by using the Exhaust Gas Oxygen Sensor Socket while disconnecting its electrical connector and apply penetrating lubricant to aid the removal process. When installing the new HO2S you should apply high temperature nickel anti-seize lubricant to its threads using a light coat. The correct torque setting for the HO2S installation must be determined followed by tightening the sensor to 46 Nm (34 lb-ft) with the Exhaust Gas Oxygen Sensor Socket. Finally, reconnect the HO2S electrical connector.

Lincoln Oxygen Sensors

If you own Lincoln and want to keep it in top shape, choosing OEM Oxygen Sensors is a smart move. They are precisely engineered and follow strict factory standards. They are made in advanced facilities that use cutting edge technology. Each part goes through thorough testing to confirm strength and safety, so you can trust it. FordPartsDeal.com gives you genuine Lincoln Oxygen Sensors at some of the affordable online prices without cutting quality. Every OEM Lincoln part includes the manufacturer's warranty, easy returns, and super-fast delivery. So why wait? Shop now and get your vehicle back to peak condition.

Luxury automaker Lincoln Oxygen Sensors, a precisely engineered part, is applied to measure exhaust oxygen levels to enable the engine computer to adjust the fuel delivery to clean up performance and make it more powerful. All the Lincoln sedans and SUVs in the market today enclose passengers in a hush that is almost library-like courtesy of the Quiet Flight methodology that closes the wind openings and lets a coating of acoustic glass overlay the interiors. Long traffic crawls are transformed into lounge time by the usage of soft bridge-of-wear leather, open-pore wood, and bright and peaceful digital gauges. Co-Pilot 360 maintains a watch over lanes, blind spots, and high beams, whereas ActiveGlide allows you to avoid the wheel during approved highways, which is a blessing when you are on holiday slogs. The brand updates software automatically, and you wake up having new tricks without going to an automaker. Regular feedback from owners will ensure every Lincoln is improved regularly rather than waiting until it requires a complete overhaul, which will preserve their operational sanity. The task is easy when reaching a time to replace Oxygen Sensors and your good old Lincoln is running like the first day. Allow the exhaust to cool, unscrew the battery, find the sensor on the manifold or pipe, unplug the sensor, loosen the sensor with an O2 socket, wipe the bung, apply approved anti-seize on the new Oxygen Sensors thread, hand-start and screw the sensor on without gorilla strength. Connect the connector and battery back on, start the engine, clear the codes, and the renewed Oxygen Sensors provide clean data and your Lincoln sips fuel and eliminates emissions.
