Pontiac Letters and Arrow Head

Use dental floss, 4lb fishing line, or stiff piece of plastic/paper to work through the glue that holds them. There are holes behind the arrow head however.


The 05 GTO has a really bad thin paint. Get The clear Bra 3M stuff, it really helps.

Press unlock button once for left door. Press and hold for .5 seconds for both or press twice. Turn signals flash twice, and horn chrips twice. If chrips 5 times then there is a problem with the door lock. If lock system is overloaded, power supply is cut for 30 seconds. If they flash three times (the lights) when pressing unlock, then an attempted break-in has occurred (turn ignition on, look at trip computer display for the ALARM ACTIVATED message. They will show until the trip computer MODE button is pressed).

Power Steering

The GTO power steering system uses Dexron III ATF. Make sure you USE ATF, and not Power Steering Fluid! Your pump will go out using power steering fluid.

Changing the Power Steering Fluid.

Do not reuse any drained power steering fluid regardless of appearance or condition.
