The security light came on my 2002 buick centry

You need to scan for ABS codes. If ABS light is on you will have normal braking only.

My 1987 buick centry limited cuts off when i drive but when i start it back up it will start right bacc up at times some times it starts and die agin but when it dies the battery light and service engine light comes on but once it starts the service engine and battery light goes away and dont do it agine tell it cuts off agine

the 2002 buick century does not have a 3.6L V6 it has a 3.1L V6 in order to replace the thermostat you have to remove the exaust crossover pipe the book time is 2.4 hours so it is a pretty good job...good luck

i have a 1995 buick centry and my anti lock light came on should i be concerned about anything? my bracks work fine.

computer reading is right front excess speed variation what does that mean?

just remove the tire and hub. then it should slide out

your auto headlamps are operated from a photo (light) sensor on the dash.-thats where you start and end, just replace the sensor...wow $800, they were gonna rob you blind!

drop the gas tank

You might want to check the ECT (engine coolant temperature sensor) It could be defective and telling the PCM (car's computer) that the engine coolant is cold all the time.
