SOURCE: serpentine belt replacement
You will only need to locate the fan belt diagram to replace it on correctly and a 1/2 breaker bar or ratchet to back off the tension er while replacing belts check the tension-er bearing if it feels ruff when you turn it replace it. Check water pump also to see if it turns smooth same with the alt.
SOURCE: adjust a headlight 2005 grand prix
The adjustment screws/nuts should be located either on the top of the headlamp assembly,
behind the headlamp assembly, or near the frame rail by the radiator
support.
You will have vertical adjustment screws for each independent beam
(separate highs and separate lows, but will be same screw if highs and
lows are the same bulb). You may also have additional horizontal
adjustment screws as well
Park
your car on a level ground 30 feet from a wall and measure the height
from the ground to the bulb and mark on a wall (do this for highs beams
and low beams if the bulbs are separate, if highs and lows are the same
bulb, only do it for the lows)
For Low Beams: If the headlights read VOR, then
aim the brightest part or cutoff part just below the mark on the wall.
If it says VOL or nothing, aim them 2 inches below the mark on the wall.
For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
SOURCE: how to remove the door panel on a 2005 grand prix
Just an philips screw, you'll need to remove screws that are by the door handle,
arm rest, under door and side of door and then gently pull back on the
panel as there will also be retaining clips attached and you don't want
to break them.
If needed, you can pull back the weather seal
(can't reuse it, but it's not that important) and you will be able to
access everything inside the door.
Hope helped with this (remember rated this).
SOURCE: 2005 pontiac grand prix, code p0641 came on. What
DTC P0641 The powertrain control module (PCM) provides a 5-volt reference to the
following sensors:
The throttle position (TP) sensor 1
The accelerator pedal position (APP) sensor 2
The engine cooling fan speed sensor
The AC pressure sensor
The fuel tank pressure (FTP) sensor
The oil pressure sensor (OPS)
The PCM monitors voltage on the 5-volt reference circuit. If the voltage
is higher or lower than required, DTC P0641 will set.
Conditions for Setting the DTC
The PCM detects a voltage that is higher or lower than required on the
5-volt reference circuit. The above condition is present for 1 second. Action Taken When the DTC Sets The control module illuminates the malfunction indicator lamp (MIL) when
the diagnostic runs and fails. The control module records the operating conditions at the time the
diagnostic fails. The control module stores this information in the
Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3
consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and
passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures
are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool.
Yes i can be dangerous, depending which issues mentioned above has triggered the code such as a faulty gas peddle position sensor. the code can also cause a reduced engine power to activate.
Thank you for using Fixya and best advice is to have the dealer address these issues. A tech 2 scanner would be needed to address the P0641 DTC code.
