Detaching the Oxygen Sensors
Oxygen sensors monitor the oxygen content material within the exhaust gases and supply suggestions to the engine management module (ECM) to regulate the air-fuel combination. To detach the oxygen sensors from the Subaru Legacy 2017, comply with these detailed steps:
- Find the oxygen sensors on the exhaust manifold or exhaust pipe. There are normally two oxygen sensors, one upstream and one downstream of the catalytic converter.
- Clear any grime or particles across the oxygen sensors utilizing a wire brush or compressed air.
- Disconnect {the electrical} connectors from the oxygen sensors by urgent down on the discharge tab and pulling them straight out.
- Use an oxygen sensor wrench or a 22mm open-end wrench to loosen the oxygen sensor from the exhaust manifold or pipe. Watch out to not overtighten the wrench, as this will injury the oxygen sensor.
- Pull out the oxygen sensor from the exhaust manifold or pipe.
**Warning:** Don’t pull on {the electrical} wires when detaching the oxygen sensors. This may injury the wires and have an effect on the efficiency of the oxygen sensors. - Examine the oxygen sensor for any indicators of injury or contamination. If the sensor seems broken, change it with a brand new one.
- Utilizing a wrench, fastidiously loosen the nuts and bolts that safe the mounting brackets to the catalytic converter.
- As soon as the nuts and bolts are free, gently pry the mounting brackets away from the catalytic converter utilizing a flat-head screwdriver or pry bar.
- Disconnect any electrical wires or sensors that could be linked to the mounting brackets.
- Take away the mounting brackets from the automobile.
- Examine the mounting brackets for any injury or corrosion. If any injury is discovered, change the mounting brackets earlier than reinstalling the catalytic converter.
- Lubricate the bolts and nuts with an anti-seize compound to stop them from seizing sooner or later.
- Put on security glasses and earplugs whereas slicing.
- Help the exhaust pipe to stop it from falling.
- Use a pointy blade for a clear reduce.
- Park your automotive on a degree floor and interact the parking brake.
- Enable the engine to chill fully to stop burns.
- Put on gloves and eye safety.
- New catalytic converter
- Wrench set
- Socket set
- Oxygen sensor socket
- Penetrating oil
- Exhaust sealant
Eradicating the Mounting Brackets
To take away the mounting brackets from the catalytic converter, comply with these detailed steps:
After eradicating the mounting brackets, you may proceed to take away the catalytic converter from the exhaust system.
Chopping the Exhaust Pipe
Step 7: Making the Cuts
To make exact cuts, mark the precise places the place the catalytic converter can be eliminated:
– **Entrance Lower:** Measure 6-8 inches away from the catalytic converter towards the engine and mark.
– **Rear Lower:** Measure 6-8 inches away from the catalytic converter towards the tailpipe and mark.
Utilizing a reciprocating noticed or a hacksaw, fastidiously reduce by the exhaust pipe on the marked places. Make sure the cuts are straight and clear.
