SOURCE: drain the antifreeze on a oldsmobile silhouette
Under the bottom of the radiator on the there is a drain ****, you will have to raise the car and crawl under it to see it, be careful to not break it, the screw in plug is fragile, it will be hard to unscrew.

first, code b0100 is a fault in the restraint system. front end sensor, restraint sensing diagnostic module or communication between the 2 are suspect problems po420 is an efficiency problem with catalytic converter. most likely would need new converter, but exhaust leaks and oxygen sensor malfuctions can also set code. if this vehicle is under 80,000 miles and does need converter, dealer should repair for free under warranty. that is federally mandated.

The first thing i would check is all 4 abs sensors at the wheels.You can do this with a volt meter set on ac voltage and spin the wheel if it generates voltage at all on the meter its good.
SOURCE: Getting DTC code P0404 and P0420. What should I do?
The 420 will not go away with egr replacement. it means the computer has detected a problem with the catalytic converter. eGR valve is at the rear of the engine. Not easy to get to on vans.
