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.

Some are in the inlet to the evaporator and some could be in the condenser line. You can get a new orifice tube on autozone for $5 - 20

SOURCE: Low Coolant light flashing on 1996 Buick Regal 3.8

The low coolant sensor should be located in the passenger side radiator tank, You need to take it out and clean the sludge off of it for it to work right. Or you can just unplug it and forget about it, the light will go out and it won't cause any problems.

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)

93 buick. Century blow back tank boiling


If you are talking about the coolant over flow??? You may have a bad radiator cap, maybe low on coolant, maybe thermostat. You haven't provided a lot of details here so it's hard to say for sure.

2002 Buick Century continue to run hot although I have replaced the thermastat and the radiator and checked anifreeze levels - what's else could be wrong?


Turn your a/c on, both fans will start. The temperature switch is located on the intake behind the thermostat housing, but it isn't near as hard to replace.

Heater on 2003 Buick Century only works when the rpms are up


Your likely problem is low coolant level. Check to make certain that your coolant level is topped up in the radiator and that coolant is also in the reservoir at the appropraite level as shown when on container when the engine is hot or cold. When the coolant is low, you have to have higher RPMs to get the coolant to pump through the system and heater core.

Radiator Electric Fan Motor on a 2003 Buick Century won't come on when temp gets high


I have a 1997 Buick Century with the same problem. Both my fans work if the A/C is
on as they should. If your turn off the A/C the passanger side fan will not come on
and at an idle the coolant in the radiator will boil, you can hear it in the overflow tank.
If you are driving there is enough air flow thru the radiator that the coolant doesn't
boil and the car doesn't overheat. I have replace the water pump, the thermostat.
and the ETS or engine temperature sensor mounted just above the thermostat in
the thernostat housing, to no avail, I still have the same problem. The only other
thing is the coolant level sensor in the radiator, which I haven't replace yet due
to the fact you have to pull the radiator in order to replace it, which is a major
undertaking. I have a low coolant indicator on all the time on the dash so I have
a pretty good idea the coolanat level sensor is bad. The coolant level is not low
so that sensor is not working as it should. I hope this may help with your problem.
To test you fan raise the hood when it is cold and top off the radiator and fill the
overflow tank to the cold mark. Start the car and let it idle with the A/C off and
see if the drivers side fans comes on. It will have to get to operating temp
before the fan will come on. If it doesn't come on replace the radiator low coolant
sensor on the passanger side of the radiator. If that doesn't fix the problem
replace the thermostat and the Engine Temperature Sensor at the thermostat
housing with an A/C Delco Engine Temperature Sensor. Good Luck..

Low coolant light


In the surge tank, there is a sensor that detects the level of the coolant. It's most likely the sensor is stuck on the low position. All this sensor does is slide up and down as the coolant level goes up and down. You can tap the side of the surge tank near where the sensor plugs in and see if it will dislodge. You'll see the 2 wire plug at the bottom of the tank towards the front.
