Well my friend hate to be the bearer of bad news but here it is

if you have been running hott for and extended period of time with a high milage vehicle most likely your head gaskett is blown...remove the rad cap (cold) and take a sniff if smells burnt you will have to get some motor work

What octane gas should I use for a 1996 Buick Century

Most vehicles are designed to run on 87 octane, unless specified different in the owners manual. The knock sensors on your engine will detect an engine knock and advance or ****** the timing accordingly. If your engine is spark knocking, your "Check Engine" light should be on detecting a faulty knock sensor, hope this helps, Gary

The heat in my 1999 Buick Century stopped working

could be a vacuumn device in the heater system itself, or a thermostadt problem just above the water pump, unless you have more than minium experience with repairing autos, take it to a good mechanic, should be less than $100 fix.

Lights not working well

mine does it too i think they all do after time it's actually a non-replacable bulb. you have to replace the whole cluster once you pull the the dash apart its one plug and four screws. or you can knock on it in the area where it tells you the gears and miles and it will light up (like your knocking on a door)
