Hello jameli_noman: My name is Roger and I will help you. The radiator has a sensor in it that is supposed to since low coolant. A couple of things can cause a problem. 1. The sensor is working and coolant is low. 2. Coolant sensor is defective. 3. Coolant sensor is contaminated by oil deposits. I would look at #3. If you were low on coolant? The coolant had to of gone somewhere. Look close at the corners of the intake manifold. Where the intake meets the cylinder heads. If you see what looks like a slimy oozy build up and you should see traces of coolant in this mess. You have a intake gasket causing the problem. This leak will let minute amounts of oil into the coolant system. This will cause the sensor to be contaminated. You can disconnect the sensor. But this defeats the early warning of low coolant and engine damage. Should you have any more questions please just ask. I will reply. Please rate the answer as this way I know it was of use. Thank You for using Fix Ya. Roger

Low coolant light, temp normal


try adding it via the reservoir. make sure you have a 50/50 mix of water and antifreeze. If you want to cheat, cheat on the side of more antifreeze than water. Look for a leak in the hoses and water pump to find out if she has a larger problem that is causing the loss of coolant. look for drips under the car.

'98 Century--Sporadic over-heating


Be sure to have heater (not defrost) on when refilling rad with coolant, and leave cap off until rad fan has come on & off 2 or 3 times, then replace cap. Airlocks are common on vehicles cooling systems, and will cause symptoms you are describing.

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.
