Bank 2 Sensor 1 is on the driver side - follow the right side of the engine down the headers which attaches to the catalytic converter. The o2 Sensor you're asking about (Bank 2 Sensor 1) is before the Catalytic. The o2 Sensor after the Catalytic is Bank 2 Sensor 2. Bank 1 Sensor 1 is on the passenger side as well as Bank 1 Sensor 2.

Timing Belt & Sprockets Removal & Installation 3.2L Engine To Remove:
TDC compression stroke timing marks gm_car_cad_cts_04_tmg_mrks_tdc_comp.gif

  1. Before servicing the vehicle, refer to the precautions at the beginning of this section.
  2. Remove or disconnect the following:
    • Timing belt cover
    • Crankshaft damper
  3. Rotate the crankshaft in the engine rotation direction, clockwise using the J 42098 or other suitable tool until the # 1 cylinder is at Top Dead Center (TDC) on the compression stroke. The reference marks on the camshaft gears should be aligned with the corresponding notches on the rear timing belt cover, as well as the mark on the crankshaft sprocket and oil pump housing. Timing marks 60 degrees from TDC gm_car_cad_cts_04_tmg_mrks_60_frm_tdc_comp.gif

  4. Rotate the crankshaft counter clockwise using the J 42098 or other suitable tool until 60 degrees Before Top Dead Center (BTDC). The 60 degrees BTDC point can be identified by the index mark on the oil pump cover. Using the J 42069-10 or other suitable tool gm_car_cad_cts_04_j42069-10.gif

  5. Install the J 42069-10 or other suitable tool to the crankshaft sprocket with the knurled bolt.
  6. Rotate the crankshaft in the engine rotational direction, clockwise using the J 42098 until the lever of the J 42069-10 or other suitable tool firmly contacts the water pump pulley flange. The # 1 cylinder is at TDC at this point.
  7. Secure the moveable lever of the tool to the water pump pulley flange. Tools in cam gears gm_car_cad_cts_04_tools_in_cam_grs.gif

  8. Install the J 42069-1 and the J 42069-2 or other suitable tools to the camshaft gears. If the J 42069-1 or the J 42069-2 or other suitable tools do not fit into the teeth of the camshaft gears, it may be necessary to loosen the upper idler pulley and turn the eccentric or camshaft gears until the tool can be inserted.
  9. Loosen the timing belt tensioner nut.
  10. Loosen the upper idler pulley bolt.
  11. Remove or disconnect the following:
    • Lower idler pulley bolt
    • Lower idler pulley and spacer
    • J 42069-10 or other suitable tool from the crankshaft sprocket WARNING
      After timing belt is removed, never turn camshaft and crankshaft independently. Do not remove J 42069-1 and the J 42069-2 or other suitable tools while the belt is removed.

A/C water leak, passenger side Where

A/C water leak, passenger side Where is the drip pan located?

Posted by on

Answer

  • Most Helpful of 2 Answers

I have a similar problem with a 2003 cadillac cts. The water drips from the bottom area of the glove compartment. If you would stick your hand under and feel around, there is a removable panel ( two small bolts and one star screw) there , you will fell the sponge on the other side of the panel is wet. I removed this panel and ran the air conditioner and place a large mirror on the floor and shine a flash light up but did not see any water dripping.
The Driver side has a similar panel, I removed that also but saw nothing, not even the canister. But the out side pipes from the AC show the canister leads in the hood under ther driver side.
Any way I looked under the car and found the drain hose. It is located under the driver seat area. I tried fishing a coat hanger through it and it went a long way up. If you look on the side panel where the parking brake is located you will see this hose going to the top of the hood. You will need to depress the parking brake for a better view. I tried the Ac bot no condensation water came throug.
I late found a similiar hose on the passenger side. I tried to push the wire in but did not get too far.
One of these hoses drain the Sun ( moon) roof.
I then took a cap from a silicone tune ( u know the screw on tip that you cut at 45 degrees) That I inserted into the tube under car, then I insert a small funnel into the silicone cap , next with my garden ready and flowing , I force water up through the AC drain hose. Dont do too long, 5 to 7 secs is good. You will see the water come through the other drain hose. It is best to have some onlookers. Note some water might flow up to the moon roof drain and into the car so place some towel on the seat.
That works for me.
Thanks all
and good luck

ok, woodhujr,if im not mistaken you had another help request of cranckcase pressure...that problem is causing your leak.
ccny, i have no idea what you are talking about, feel free to enlighten us...
Howard, the best advise i have for you in replacing the valve cover gasket(s) is to get a repair manual for this car/engine and follow the steps as outlined there. I couldnt try to give you step by step instructions in this little box without way oversimplifying.

The ABS, Traction Control and Brake Warning Lights

The ABS, Traction Control and Brake Warning Lights came on in my 2003 Cadillac CTS. I took it to a mechinac who turned the rotors and replaced the pads. The lights came back on but the brakes seem perfect. The mechanic did not know how to reset these warning lights. Do the lights mean there may be another problem or do they need to be manually reset and, if so, how do I do it.
