SOURCE: how to replace a coolant level sensor, 2000 buick century

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

SOURCE: Trying to flush the radiator--cannot find the bleed valve for coolant.

The drain should be on the drivers side at the bottom of the radiator, facing the driver. It's a plastic "wing" that unscrews. There should also be a bleeder for exhausting the air from the system when you refill. The bleeder I'm familiar with is a brass screw screwed into the thermostat housing. (where the top hose attaches at the engine)

One good way to find where a coolant leek is coming from - is - when you get home and the car is good and warmed up - "hot".. Park it up on ramps if you have them.. Right after you shut it off - it will build even more pressure in the cooling system.. At this time car is off - open the hood and look (from under the hood and from under the car if you have ramps) for leeks,, listen for the "hissssss".. If the leek is just to small and/or to difficult to find - take it to a shop or oil change place for a compression test of the cooling system to locate the leek..

Hopefully its just a hose leek..


Good luck..

I can't locate the radiator drain plug on my 2001 buick century. Help!


Not all radiators have them, just remove the lower radiator hose and spray hot water through it from the top till it comes out clear, usually works better anyhow... Note: if your coolant is nasty and all brown and gummed up its cause you have a leaking intake gasket and oil is mixing with your coolant,, if this is the case you may have to replace the radiator as well as the gasket on the intake..

How do i drain the old coolant from radiator. does the drain plug comes out or just turns to one direction. thanks


hi,, yeah you just turn it out, right to tighten, left to slacken, remember to remove your cap and leave a hose of running water flowing through the radiator to help wash out all the old stuff.

PS.. IF cant find the radiator drain plug, remove the button radiator hose..

I have a 2002 buick century custom. Apparently there is a problem with the antifreeze that was used in these vehicles. What do I need to do to repair the damage caused by this problem


You need to drain the old antifreeze and flush the entire cooling system with a commercial product such as Prestone Super Flush. After flushing according to the directions on the product you will want to fill the cooling sysstem with plain water and let it circulate through the system. Drain the system again and repeat the process until the water is clear of any antifreeze. Refill the system with the proper mixture of antifreeze. Make sure you use a quality antifreeze that is compatible with your make and model of car. The auto parts store personnel can help you select the right antifreeze. DO NOT refill it with Dexcool. That is the antifreeze that GM put in originally that is causing the problems. Dexcool not only forms a gummy sludge in the cooling system, it also attacks certain gasket materials and causes coolant to leak into the engine. Hopefully, this hasn't happened yet.

2002 Buick Century - low coolant indicator lit up twice in an hour and hasn't done it again. The dealership suggested a complete coolant flush and radiator flush. They said lower intake gasket is leaking...
