I HAD THIS PROBLEM ALSO ON MY 2002 BUICK CENTURY AT ABOUT 58,000 MILES. I HAD NO PROBLEMS WITH OVERHEATING OR ENGINE MISS OR POWER. THE WAY I TOOK CARE OF THIS PROBLEM WAS TO DRAIN ABOUT 1 GALLON OF COOLENT FROM THE SYSTEM AND POUR ABOUT A QUART OF LIQUID CASCADE AUTOMATIC DISH WASHING SOAP IN THE RADIATOR . YOU NEED TO REFIL THE SYSTEM WITH PLAIN WATER AND BLEED ALL THE AIR OUT OF IT. IF YOU DO NOT BLEED THE AIR OUT IT WILL OVERHEAT QUICKLY. AFTER YOU GET ALL THE AIR OUT DRIVE IT ON THE HIGHWAY AND GET THE CAR UP TO NORMAL OPERATING TEMP FOR ABOUT AN HOUR OR SO. I LEFT MINE IN FOR ABOUT 200 MILES. THE REASON BEHIND CASCADE IS IT WILL NOT FOAM LIKE SOAP AND IT BREAKS THE OIL DOWN. AFTER HIS IS DONE HAVE THE SYSTEM FLUSHED AND REFILLED WITH DEXCOOL ANTIFREEZE. AFTER I DID THIS 5000 MILES LATER NO OIL IN COOLANT. I DON'T KNOW WHY,BUT NO MORE OIL.

#101 of 575 This Is *NOT* A Tire Problem
Feb 10, 2006 (7:02 pm)
Have taken our '99 Century (70,000 miles) to dealership twice. Both times they insisted that the tires were out of round, unbalanced. Not at all the case. (I'd just put new tires on the first time. Put more new ones on the second time. Problem not solved.) PROBLEM: When driving between start and up to about 25 miles per hour, the car feels like the front right and back left tires a waaaay out of round. I can watch my hands moving back and forth on the steering wheel. When getting up to normal speed (45ish +) roughly 90% of the problem goes away. Dealership says they've checked everything and have no idea. (I'll save the electric window system failures for another time.) Any ideas? Thanks in advance for the help.

I had the head gasket replaced, that fixed the problem. Too cold here to run water through the rad.
You would think something as important as the head gasket wouldn't look so flimsy!!!!
But the car is all good now, runs like a champ!

That condition is almost always caused by a defective tire (usually a shifted belt) or excessive lateral runout in a wheel. Simple task to check the wheels with a runout gauge to verify they're running true.

I've got a 98 Buick Century and the mechanic said I needed the owners manual to turn off the light. I bought the car from my grandfather who has alzheimers and he's lost the manual and (obviously) doesn't know where it is. Anybody know how to turn the light off?

The powertrain control computer has detected an out of range signal from one of it's monitored sensor circuits, stored a diagnostic trouble code, and turned on the CEL. Start by having the codes retrieved (AutoZone will do it no charge) and repairing the fault.

#107 of 575 1999 Buick Century Relay location

Does anyone know where the relay is that turns the headlights on automatically at night. This same relay turns on the dash lights automatically. It is not located in the relay box or fuse box on the firewall. Anyone know where this is? 1999 Buick Century Custom. Mike
