How to Install a NTK Performance Oxygen Sensor (Front) on your 2011-2014 GT Mustang

• NTK sensors are designed for the use in automobiles only

• Use the correct part number as listed in the application listing

• DO NOT drop or use an oxygen sensor that has been dropped as this may have caused shock damage to the ceramic element

• DO NOT use any compounds on or around the sensor unless labeled as oxygen sensor friendly products

• DO NOT use impact wrench or conventional socket type wrench to install sensor

• DO NOT allow sensor or lead wire to touch exhaust manifold or any other hot component

• DO NOT expose this product to water, oil, windshield cleaner, anti-corrosion oil, grease, terminal cleaner, etc.

• DO NOT use leaded fuels, silicone or metal based additives

• DO NOT store under high humidity conditions

1. DISCONNECT OLD OXYGEN SENSOR CONNECTOR FROM VEHICLE HARNESS USING EXTRA CARE NOT TO DAMAGE CONNECTOR, AS IT MUST BE REUSED.

2. REMOVE OLD SENSOR FROM VEHICLE USING AN O2 SENSOR SOCKET OR 22MM WRENCH. PLACE THE OLD AND NEW OXYGEN SENSORS SIDE BY SIDE

ON A FLAT SURFACE, PREPARING TO MAKE AN ACCURATE CUT OF THE LEAD WIRES. CUT THE LEAD WIRE(S) OF THE OLD SENSOR TO A LENGTH THAT

WHEN THE PLUG END IS SPLICED TO THE NEW UNIVERSAL SENSOR, THE OVERALL LENGTH WILL BE THE SAME OR SLIGHTLY LONGER THAN THE OLD

SENSOR.

IMPORTANT!! (BEFORE MAKING THE CUT, ADD 2” TO 3” OF ADDITIONAL LENGTH TO THE PLUG END TO ALLOW FOR THE EXTRA WIRE NEEDED

WHEN MAKINGTHE STAGGERED SPLICE) - SEE FIG. 1 (PG 3)

3. STAGGER-CUT WIRE LEAD(S) STRIPPING OFF APPROX. 1/ 4” OF INSULATION FROM THE END OF EACH WIRE.

>>> FOR STEPS #4 AND #5 PLEASE REFER TO THE ATTACHED WIRE PLACEMENT & COLOUR CODING DIAGRAMS

(PAGES 4-12) TO DETERMINE PROPER WIRE MATCHING OF UNIVERSAL SENSOR LEAD(S) TO CONNECTOR LEAD(S)

FOR EACH SPECIFIC APPLICATION (HEATER WIRES ARE NOT POLARITY DEPENDANT

4. A) ON UNIVERSAL SENSORS WHERE HEAT-SHRINK TUBE(S) ARE ALREADY INSTALLED: INSERT JUST STRIPED PORTION OF WIRE(S) INTO CRIMP

TERMINALS OF NEW SENSOR AND CRIMP TERMINALS

B) ON UNIVERSAL SENSORS WHERE HEAT-SHRINK TUBE(S) ARE NOT INSTALLED: INSERT JUST STRIPED PORTION OF WIRE(S) INTO CRIMP TYPE "BUTT"

CONNECTORS (APPROX. 1/4”) AND CRIMP.

5. AFTER ALL CONNECTIONS HAVE BEEN MADE, SLIP THE HEAT SHRINK TUBE OVER THE CRIMPED CONNECTIONS AND HEAT THE TUBE WITH AN APPROPRIATE

HEAT SOURCE UNTIL THE CONNECTION IS COMPLETELY SEALED, TAKING CARE NOT TO OVER-HEAT OR BURN TUBING (SEE FIG. 3, PG 3).

6. REMOVE PROTECTOR CAP JUST PRIOR TO INSTALLATION

A) FLANGED APPLICATIONS- (WHERE FLANGE IS NOTALREADY INSTALLED ON SENSOR) INSTALL FLANGE TO EXHAUST MANIFOLD FIRST, THEN MOUNT

SENSOR IN FLANGE (A COPPER GASKET IS BONDED TO THE FLANGE & NO ADDITIONAL GASKET IS REQUIRED)

B) FLANGED APPLICATIONS- (WHERE FLANGE IS ALREADY INSTALLED ON SENSOR) (IT IS IMPORTANT TO USE THE SUPPLIED GASKET BEFORE

INSTALLING SENSOR)

7. IF NOT ALREADY COATED, APPLY (ENCLOSED) ANTI-SEIZE TO OXYGEN SENSOR THREADS

8. INSTALL SENSOR BODY ENSURING LEAD WIRE IS NOT TWISTED OR BENT

9. INSTALL ALL SENSORS WITH NEW GASKET SUPPLIED & TORQUE TO PROPER SPECS AS BELOW:

M18 SENSORS - INSTALL FINGER TIGHT THEN 1/2 -3/4 TURN WITH WRENCH / O2 SENSOR SOCKET 35-45NM

M12 SENSORS - INSTALL FINGER TIGHT THEN 3/4 - 1 TURN WITH WRENCH / O2 SENSOR SOCKET 18-23NM

10. CONNECT AND ROUTE LEAD WIRE AS ORIGINALLY INSTALLED

Warning: Anti-seize compound may cause irritation to the skin or eyes. In case of contact, wash affected area with soap and water. In case of eye contact, flush with water for 15 minutes. If irritation persists, consult a physician. If swallowed, do not induce vomiting.

Keep out of reach of children.

THE FOLLOWING ILLUSTRATIONS REPRESENT THE MOST COMMON CONNECTOR TYPES FOUND ON THE MAJORITY OF DOMESTIC AND IMPORT APPLICATIONS IN USE. NOTE THAT THIS IS NOT AN ALL INCLUSIVE LIST AND APPLIES ONLY TO THE NEW O2 SENSOR. WIRE COLORS ARE INCLUDED FOR CONVENIENCE AND MAY VARY ACCORDING TO DIFFERENT MANUFACTURERS. HOWEVER, PROPER WIRE PLACEMENT AS SHOWN IN THE ILLUSTRATION SHOULD BE FOLLOWED.

MAKE SURE THE POSITION OF THE OLD CONNECTOR MATCHES THE DIAGRAM AND CONNECT NEW SENSOR WIRES AS INDICATED (HEATER WIRES ARE NOT POLARITY DEPENDANT.
