READ THIS FIRST - YEAR COMPATIBILITY INFORMATION
  • If you get the same year speedometer as your car, it will work 100%
  • 05-06 work with 05-06 and everything will work fine
  • 05-06 will partly work with 07+, you will only see the mileage and temperature, you lose all other DIC features
  • 07 will work on 08+, everything will work except the TPMS light (TMPS still works though)
  • 08-10 work with 08-10, everything will work
  • The speed will recalibrate and will show the correct information if changing from 120mph to 140/160 cluster
  • You can buy speedometers on ebay for $60-110 shipped
  • LS/LT/SS/Sport doesn't matter. Coupe/Sedan doesn't matter.

Tools Needed
Phillips head screwdriver - preferably a short one
Flat head screwdriver or small chisel
7mm socket
Socket ratchet/wrench with extensions
New speedometer/gauge cluster

This can take anywhere from 30 minutes to 2 hours depending on your tool handling skills are.

1. Start by removing the lower dash panel. This is the big piece under the steering wheel and has the compartment for your coins and trunk release. It is attached with clips. Pull on it, it may seem like you will break it, but you won't. You can use a "How to remove your dash" guide if you need more help.

2. Remove the dash pieces on the left and right side of the steering wheel. It has the dimmer and fog light switch.

3. Move the steering wheel all the way down. There is a little lever that locks the position on the bottom left side on the steering wheel.

--------------
4. Now under the dash pieces you removed is 1 bolt and 1 washer, star looking piece on each side. You need to remove the bolt. You also need to remove the washer piece by using the flathead screwdriver. Just wedge it out. This took the longest for me. You can cut it and break it if you want, it doesn't serve much of a purpose, I didn't put it back at the end.




--------------
5. On the roof of the cluster dash piece (that's what i call it) are 2 screws. Remove these using your short phillips head screwdriver.



--------------
6. Now the tricky part. Remove the cluster cover. This will require some tugging and bending and pushing. Be careful not to break it. Just try to remove it and you will figure out how to remove it.



--------------
7. Now there are 4 bolts holding the speedometer in place. 2 on the top, 2 on the bottom. Using your ratchet and extensions, remove the bolts. Be careful not to drop them.



--------------
8. Now pull the speedometer out a little. There is a wire connected in the back. Push down on the top of the connector to remove it. Once the wire is removed, pull the speedometer out. This also requires tricky hands.




--------------
9. Put the new speedometer in and plug the wire in. IMPORTANT: Turn the car to the ON position and test all the lights and DIC features to make sure it all works.



--------------

10. Once everything is working, put everything back.
11. Screw in the 4 bolts onto the speedometer.
12. Put the cluster dash piece back in.
13. Put 2 screws on the roof of the cluster dash piece.
14. Put the 2 bolts on the left/right under the dash piece. OPTIONAL: You can put the star washer things back if you want.
15. Put all the dash pieces back.

You are done!

i was just wondering (if its a dumb question sorry lol)

but i noticed you changed the gauge sticker? well the thing that says your speed and gas and rpm. you went from one that had a max speed of 110-120 (like my cobalt) and upgraded it to a nice one with the max speed now 180. does the speedometer reconfigure for that too??
because isnt it just like paper and the computer doesnt know that now the 60 mph is now further down, instead of at the top like it was?

:confused:

I didn't change the "sticker" face. I changed the whole unit. The car's "onboard computer by the engine" (BCM) sends a 50mph digital signal. The speedometer/RPM knows what a 50mph signal is. It will display 50mph accordingly. If i changed the "sticker" face on my old 120mph unit to a 160, then it would not be correct.

Was anyone able to confirm if a g5 cluster would work? I was literally about to hit "buy item" on a white 140mph cluster on ebay, but would like to check out the red g5 clusters as well...if they work

Think its the same as with our cobalt clusters? As in, same year means everything should work kind of deal?

I checked another cobalt related forum and they have a thread of one guy talking about his 140mph cluster that he has in his cobalt. He mentions its the same guidelines as before with only needing to match up years.

I have an 05 LS, so that means an 05 or an 06 g5 cluster would work for me then, yes? I googled around for a 2005 g5 cluster, but didnt see any yet.

Most people think that the only way to swap clusters is with the same year, thats not true.

Yes, any 05 or 06 cluster will work for you, there are a few on ebay (search "chevy cobalt speedometer")
