#1124 of 1492 Re: Antifreeze [rayt2] by phaedrus411 Aug 19, 2005 (5:53 am)
Replying to: rayt2 (Aug 15, 2005 6:47 am) Don't use DexCool unknowingly. This antifreeze, though marketed as "sterile", has been shown create a residue in the cooling system that can block flow and even eat away at the gaskets. This is not smoke and mirrors; there are several class action law suits being brought against GM at the moment for their continued use of DexCool and supposed knowledge of this problem. As GM has used DexCool exclusively for a decade or so, a recall is not going happen as it would most likely cost the company in the billions of dollars.   Continuing to use DexCool probably will not harm your vehicle. Just understand that the 100,000 mile slogan is bogus. When you have your coolant changed, get the system fully flushed to remove the residue and continue change it every 2-3 years.

Replying to: oilyrag (Aug 21, 2005 12:47 pm) Removal   1. Raise the window. If the window motor is inoperable, remove the window to gain access to the window motor retaining screws.    2. Remove the door trim panel.    3. Remove the water deflector.    4. Remove the door speaker.    5. Support the window.    6. Disconnect the wiring harness from the window regulator motor.    7. Remove the 3 bolts (1) from the window motor located on the front side of the motor. IMPORTANT: Do not allow the cable gear to come out of the housing. A failure will result with the cable coming off the spool.    8. Separate the motor from the cable housing by wiggling the window motor. Observe the orientation of the window motor.    9. Remove the motor from the door regulator assembly.   Install    1. Install the motor to the cable housing by wiggling it into place. NOTE: Refer to Fastener Notice in Service Precautions.    2.

#1130 of 1492 2K SIERRA Wheel Bearing Problem ???? by shiftless Aug 21, 2005 (4:46 pm)
I have a 2000 Sierra 1500 Std. Cab, Short Bed, 4WD, 40000 Miles. At about 30 to 50MPH there is an apparent "grinding" noise that appears to come from the left front wheel. The "grinding" seems to be in time with the wheel rotation and can be felt through the steering wheel. All symptoms completely dissappear when turning to the left (at speed). All indications are pointing to a failed left front wheel bearing as the cause. The wheel bearing was replaced but the noise is the same. Any ideas out there as to what the source of the problem might be?   Ed Replies to this message: weels (Aug 21, 2005 5:00 pm) lando2000 (Nov 28, 2005 7:35 am)

#1132 of 1492 Re: 91 GMC C/K 3500 head light switch getting HOT [larryd27] by weels Aug 21, 2005 (5:12 pm)
Replying to: larryd27 (Aug 19, 2005 7:10 pm) If you have too big a fuse it will allow more current (heat) through the entire circuit including the switch. I would start looking that you are using the correct rated fuse and are the headlights stock or high powered aftermarket or are there add - on lights in the circuit? If all that stuff looks right, start looking for a short somewhere. I've had trailer harnesses go bad internally to the plug and cause this sort of thing even though the plug looked fine on the outside. Good luck.  - Tim
#1133 of 1492 driver's side rearview mirror vibration by j_appleseed Aug 22, 2005 (9:14 pm)
I have 2000 Sierra 1500 and the driver's side mirror (OEM) vibrates excessively. I ordered a new one three weeks ago and received and installed it today. It's from CIPA Mirrors. After a test drive I've decided that's it worse than the OEM one I replaced. The passenger side mirror is as solid as a rock. Maybe I just received a bad mirror. Any info is appreciated.
