This takes a deep well socket, and a little anti-seize on the threads.

Just remove the sensor, lube, and screw in a new one...then hook up your wire and your done.

SOURCE: o2 sensors on a 99 mercury cougar v6

I just got done replacing the O2 sensors in my 99 Cougar due to throwing a P0135 malfunction code. There's 3. Facing the engine there's one in the front coming off of the front header, which is easy to get to. Another more tricky one if between the engine and the fire wall on the rear header pipe. The third is under the vehicle behind the transmission pan on top of the exhaust. In order to replace the O2 sensor near the fire wall you will need to remove the 4 retaining bolts for the ECM module and move it out of the way. Additionally you will need to remove the 2 retaining nuts for a wiring harness that is seated below the ECM module. Pay close attention to the connectors because the front and under vehicle O2 sensors have round connectors the one near the firewall has a squared connector. I was able to replace all 3 by myself in approximately 35 minutes. If your throwing a O2 heater malfunction code it is most likely going to be the sensor near the firewall. make sure that you know someone with a code reader so the code can be cleared. If you're do for an emmissions inspection be sure to put at least 40 miles on the new O2 sensor with different types of driving (e.g. highway, coasting, decellerated turns and rapid acceleration). Gotta love project cars for your kids!!

Throttle position sensor may be at fault or the throttle body may need cleaning. If so equiped, the egr valve could be at fault.

1999 mercury cougar how to fix temp gauge


Remove the wire to the engine temp sensor and ground it...if dash gauge pegs replace the engine temp sensor. You can't fix the sensor, it's replace only.
If the gauge in the instrument panel is tango uniform you'll have t? replace the instrument cluster or the gauge if it's separable. Check with your lincoln/mercury dealer or Ford (they picked up mercury) dealer to find ?ut.

Where is the temp gage sensor location 2001 merk cougar


Hi there,

The temperature gauge relies on readings from the Engine Coolant Temp (ECT) Sensor.

The ECT sensor is usually located on (or near) the thermostat/coolant housing.

Refer to component No. 8 (2.0L Engine):

Refer to component No. 9 (2.5L Engine) locate under bypass tube:

Hope this helps.

1993 Mercury Cougar XR-7 V-6, Overheating


Your problem could be the coolant temp sensor, or it could be the gauge itself, but something 2 do is if you can get it to a dealer, or a parts store. If you cant get it there, you can get an OBD I scanner and retrieve the code and know why the check engine light is on, but it could be from any of the sensors on the car, would be best to get it scanned.

Temp. gauge not working after having a heater core replaced.


if the engine cooling system was not filled and air bleed out the system may have an air pocket and this keeps the gauge from reading correctly.
