SOURCE: 2002 Pontiac Grand Prix Thermostat

as you face the engine the thermostat bell is on the right (drivers side) Follow the radiatoe hose. Remove the two bolts and raise the bell still attatched to the hose. the thermostat is there with the rubber seal. You can gently pry the thermostat out with a screwdriver or something similar. Put in new thermostat be sure it is the same as the old one, and then replace or change the seal (be sure it is the smae size and thickness as the old one as I got the wrong size from Napa) Then replace the bell, and tighten, but not over tighten. I hope this helps!

SOURCE: Anti-theft code 1995 Pontiac Grand Prix

DO a google search for Radio lock codes with you make model vehicle,, for 7$ you can get it,,here is what I found for a 2000 gp..
1. Press and hold presets 2 and 3 for about 7 seconds until you get 3 digits on your display. This is the first 3 digits you will need, so write them down.

2. Press the AM/FM button to get the last 3 of the 6 numbers you will need. You only have 5 seconds to do this. If you wait too long before pressing the AM/FM button, the display will go back to LOC. If this is the case, just start over at step 1.

3. Call 1-800-537-5140, press 2 for Pontiac, press 620529 and hit the # key. The computerized voice will ask you for your 6 digit code you have written down. Enter that and press the * key. He will then give you your unlock code, and the option to get additional codes. The first one worked for me so do not worry about the additional ones.

4. Set the code into your radio by pressing the hour set button on your radio until it corresponds with the first 2 digits of your code, then press the minute set button until the last 2 digits of your code are entered. Immediately press the AM/FM button once the correct code is entered and the code SEC or "secured" will be displayed. This part of the procedure is outlined in your owners manual.

5. If you want, you can change your code so you will not forget it, or get rid of the theftlock all together. These procedures are outlined in your owners manual, read it if you would like to change these values.

6. turn on the power to your radio and enjoy.


Hints:

- The first 3 and the last 3 digits were the same on my radio. (for example first 3 were 123 and last 3 were 123) First I thought I was doing something wrong when the display wasn't changing, but I wasn't. Just to let you know it is a possibility.

- The dealer code 620529 is an actual dealer. If GM finds out that this code was leaked to the public, they will remove it from their system. If the dealer code does not work when you phone the 1-800 number, you can search for a new dealer code on the internet somewhere. If this does happen, PM me and I will try to find one that works for you.

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.
