The intake manifold was leaking antifreeze, which could cause the vehicle to overheat. Manufacturer was contacted by consumer. The engine locked up due to loss of coolant. The water pump started leaking at the shaft seal with less than 43000 miles on the vehicle. A dirty, oily substance was noticed in the radiator neck.

car   Radiator problem 2
Failure Date: 04/13/2004

I have a 1999 Buick Century , I took the vehicle to have a radiator flush and was advised that I couldn't have this job performed due to a leak or crack in the intake gasket. At this time I was very surprise to see the complaints and there is no recall. This is outrageous that no one seems to care this is a very expensive repair and should not be the responsibility of the consumer to replace. This should've been done by general motors.

car   Radiator problem 3
Failure Date: 04/12/2004

Cooling system defect in 1999 Buick Century. Cooling system is being containminated by brown substance in system, causing the system to overheat. Reported to dealer three times. They have a TSB out on this, but no clue on what is causing this. They have inspected the vehicle three times, flushed the system, and replaced the radiator cap, but problem reccurs. Now it is going in for the fouth time. Problem was not corrected under original warranty, now the extended warranty that I purchased is about to run out, yet having the same problem. If they have a TSB out on this, why can't they fix the problem once and forever?.

Failure Date: 04/20/2001

When looking under hood noticed radiator was full of gunk. Took vehicle to a mechanic, and they said this happens to all Buick Century vehicles.
