SOURCE: Changing blinker on 2007 Pontiac G6

It's a monster pain to get to them, but it's doable. Once you empty the trunk, you'll see 4 black knobs - approx 1.5 inches in diameter. You'll need to remove all of these (they just unscrew, but they are plastic, so be careful not to strip the threading) in order to access the rear light assembly.

They're in there snug, but once you find the appropriate sized socket (I wish I could recall well enough to tell you what size, b/c I remember that it WAS an odd size), you'll have to remove all 3 bolts and then push the whole assembly out from inside the trunk.

Once the assembly is out, you will see the rear of the sockets, which simply push and turn to get the lamps out of. As long as you have everything open, I suggest changing ALL of the lamps (brake, tail, and turn signal) on BOTH sides, since the lamp life for all of these is about the same and it's such a pain to get to them in the first place.

SOURCE: my cd player in my 07 pontiac g6 wont play my cds

That usually happens with computer copied discs that are too thick, and are labeled data. You need to use Audio Blanks when you record CD's. Automotive CD players can be a bit more selective when playing owner created discs. If this happens with store bought CD's you may need a CD lens cleaner.

2008 Pontiac G6. I can't get it to rev over 4000 rpm after changing the crankshaft sensor. To reset the crankshaft sensor you have to rev the rpm past 5000.

Question edited for a lot more clarity. That is the worst written English and spelling I have seen for months! :>D
Question moved to model category.

It sounds like you are in Limp Mode. Was the crankshaft sensor, a proper OEM replacement of a cheap one from Mexico or China? They come faulty as new! Don't go cheap on sensors.

Or it has a rev limiter depending on what you are doing.

Where is the crank trigger 07 Pontiac 3.5vvt

I looked at info for 07 Pontiac G6 3.5L engine, the wiring diagram shows two crank sensors. I don't know which one your talking about?
A PM/permanent magnet sensor, two wires, there are notches cut in the crankshaft for the trigger. With a hall sensor, three wires, there may be a trigger behind the harmonic balancer?

I was told I have to replace the crankshaft seal and oil pan gasket on my 2000 chevy malibu and will cost approx. $380.00. Also is the rear main seal the same thing as the crankshaft seal??? Thanks!

Well sometimes.... the front crankshaft seal is usually called a crank seal, or the front timing cover seal but the rear crank seal is (usually) called the Rear Main crank seal. In order to replace the rear seal , the transmission will need to be removed. If its the front, then the harmonic balancer will be removed. $380 sounds cheap. As you will need a oil seal, oil pan gasket, oil, filter, labor and tax. Maybe even a lower engine mount.

Rear barring an seal replaced

I'm not sure if this is the right part of your car but, are you talking about the rear seal on the engine for the crankshaft?

If so:

Rear Main Oil Seal REMOVAL & INSTALLATION Fig. 1: Rear main seal installation for the 2.3L and 2.5L engines 85553306.gif
Fig. 2: Removing the rear main seal 85553307.gif
Fig. 3: Installing the rear main seal on the 2.9L engines 85553308.gif
If the crankshaft rear oil seal replacement is the only operation being performed, it can be done in the vehicle as detailed in the following procedure. If the oil seal is being replaced in conjunction with a rear main bearing replacement, the engine must be removed from the vehicle and installed on a work stand.
  1. Remove the starter.
  2. Remove the transmission from the vehicle, following the procedures in Section 7.
  3. On a manual shift transmission, remove the pressure plate and cover assembly and the clutch disc following the procedure in Section 7.
  4. Remove the flywheel attaching bolts and remove the flywheel and engine rear cover plate.
  5. Use an awl to punch two holes in the crankshaft rear oil seal. Punch the holes on opposite sides of the crankshaft and just above the bearing cap to cylinder block split line. Install a sheet metal screw in each hole. Use two large screwdrivers or small pry bars and pry against both screws at the same time to remove the crankshaft rear oil seal. It may be necessary to place small blocks of wood against the cylinder block to provide a fulcrum point for the pry bars. Use caution throughout this procedure to avoid scratching or otherwise damaging the crankshaft oil seal surface. To install:
  6. Clean the oil seal recess in the cylinder block and main bearing cap.
  7. Clean, inspect and polish the rear oil seal rubbing surface on the crankshaft. Coat a new oil seal and the crankshaft with a light film of engine oil. Start the seal in the recess with the seal lip facing forward and install it with a seal driver. Keep the tool, T82L-6701-A (4-cyl. engines) or T72C-6165 (6-cyl. engine) straight with the centerline of the crankshaft and install the seal until the tool contacts the cylinder block surface. Remove the tool and inspect the seal to be sure it was not damaged during installation.
  8. Install the engine rear cover plate. Position the flywheel on the crankshaft flange. Coat the threads of the flywheel attaching bolts with oil-resistant sealer and install the bolts. Tighten the bolts in sequence across from each other to the specifications listed in the torque chart in this section.
  9. On a manual shift transmission, install the clutch disc and the pressure plate assembly following the procedure in Section 7.
  10. Install the transmission, following the procedure in Section 7.

  7. Tighten the housing bolts 11 ft-lb (15 Nm) plus an additional 50 degrees.
  8. Ensure that the housing did not move out of specification. Repeat step 6 if the oil seal housing is not within the specified range. Replace the rear oil seal housing if the specified measurement can not be reached.
