Oldsmobile Cutlass Supreme

I put this page together to explain four things, how to remove the radio, how to remove and disassemble the instrument cluster and how to set the clock.

Before you begin: I make no warrenty as to the accuracy of this information and I am not responsible for any damage, injury or anything else that happens as a result of you reading/using it.

Warning: A lot of this is recorded from memory. It very well could be incorrect, especially the screw counts.

Setting the clock

This describes how to set the clock on most (all?) 1988 Oldsmobile Cutlass Supremes. This may apply to simmilar models but I don't know for a fact.

1. Turn the car on (doesn't have to be running, just make sure the key is in the on position)
2. Turn the radio off (using the Power button)
3. Press the Set button, the word SET should light on the display
4. Use the Seek button to cycle through the hours and the Scan button to cycle through the minutes
5. Press the Set button to exit set mode

That worked for me. Special thanks to Kirk Kohen (who doesn't even know he helped) for posting the info in rec.autos.tech. View message on groups.google.com

Dash removal

This is required to get to the screws holding the radio and instrument cluster in place.

1. Remove the 4-5 screws from the underside of the top of the trim panel around the radio/instrument cluster
2. Carefuly slide the trim panel out and rotate the bottom upwards, it should just fit between the top of the dash and the gear selector

Radio removal

If you plan to remove the factory radio and replace it be aware that you will need an adapter kit. The radio is taller and wider than most. Also know that it has a different antenna jack than most. Before you buy a replacement radio measure the hole, mine was 1/2" too shallow to install my CD player.

1. Remove the 2 screws at the bottom of the radio bracket
2. Slide the radio out as far as it will go
3. Reach behind it and unplug the 2 connectors

Note: The wiring harness is attached to the back of the dash and may prevent the radio from coming out far enough to remove the connectors. If this happens carefully pull harder until the radio slides out about the lenght of itself, that's all the farther it will come out. If the connectors don't want to unplug, locate the red tabs at the back of them and pull the tab out of the connector, that should make them slightly easier to remove.

Instrument cluster removal

I'm doing this from memory so if it's not entirely accurate I apologize. It helps to remove the radio before removing the instrument cluster.

1. Remove the 4 screws holding the cluster in place
2. Carefully pull the instrument cluster forward, you may have to tilt it a little to get it to clear the dash
3. Reach behind it and unplug the connector

Note: The connector is actually 3 (or is it 2?) connectors attached together, you want to be careful not to get them pluged back in wrong. There is a tab on the connector that needs to be pushed to get the connector out.
