Question about 2003 GMC Yukon Denali
How much should i have to pay to replace the catalytic converter in this 2003 yukon denali
I would estimate the part is about 200. Usually there is about a 75 dollar fee for installation. Muffler shop would be keeping old one as part of price.

What may appear to be correct, can actually be INCORRECT. If you removed without touching the other two components, you definitely have the WRONG ONE.
Personally, I have never heard of having to remove torsion bars or oil pans to replace catalic conv.
If still in doubt. Let MIDAS do the job. Save yourself aggrevation. Unless you are really handy which you appear to be since you were able to remove it. Installing would be the reverse, provided you have the correct part. Suggest you take your vin number next time to the place where you bought it, they should be able to give you the correct one. If not, replace with OEM. Aftermarkets sometimes cause vehicle to fail emissions test. Goooooooooood Luck!

It is best to allow the engine to cool down for about 3-hours before starting this job. This is for safety and convenient reasons. It also helps to minimize the loss of coolant. Coolant draining into the environment should be avoided.
After the engine cools down, disconnect the negative terminal of the battery.
Location: The Denali's engine coolant temperature-sensor is located (threaded) into the cylinder-head just above the spark-plug. It is good thing to remove the spark plug wire in the coolant temperature-senor's immediate area. This will allow more room to work it out.
It is removed by first undoing its electrical plug, and then using a deep socket with wrench to loosen the coolant temperature-sensor.
Once done, verify that the electrical connector is replaced in its proper location. Then coonect back the negative battery terminal.

2003 GMC Yukon - My power mirrors stopped working.... all fuses have been checked and they are all good. Any ideas? These are the power folding mirrors. The function that allows you to fold them in for car washes etc still works.... they just will not adjust when you change drivers, or when you try to adjust them with the controls. Any ideas would be appreciated!

hi,my friend, you can try,
Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
Inspect the downstream heated oxygen sensor (HO2), replace if necessary
Replace the catalytic converter
