The vehicle is 2004 buick century. sometimes the temp guage rises and comes back down. during this time, clod air blows. sometimes the temp guage is 1/2 way and cold air blows. thermostat has been changed....


is your electric fans running constantly. and most times then not you`ll need a water temp sensor or water temp relay. usually the temp sensor on that model comes usually next to the thermostat with a little wired plug on top. or on the radiator. either way pull the plug while the motor is cold. unscrew the sensor and screw the new one in and replace the electric plug back on top of the sensor. 2 things: Cold motor, have every thing set up and ready because when you take out the sensor the coolant will start to come out. you will not loose much if you work quick. keep rags or paper towels below the sensor to keep coolant off the motor and smelling when it gets hot. you have also pour or hose off coolant after your done installing the new coolant temp sensor.

Radiator Fan for 94 centry does not come on. Engine overheats. I assume temp sensor is faulty. I have hot wired the fan to ensure the fan does work, but without those wires... no luck. I hate to just...


the ECM turns on the fan when the coolant sensor reaches a set temp. the fan is also turned on when the AC is on. there is also a fan relay in the circuit. none of these are very expensive. if the fan works when you apply direct voltage, the fan is good. replacing it will not solve your problem. an electronic component locator can show you where the temp sensor and fan relay are. your local auto parts store can look that up for you.

2000 buick century, where is the thermostat located. and what level should the antifreeze be? the temp guage on dash is staying on the c side what may be the problem?


The thermostat is in a housing on the engine. It's located where the lower radiator hose attaches to the engine. The coolant level should be right near the top of the radiator when you remove the cap, and the overflow canister should be filled to the indicated line (there are markings on the canister). If your gauge stays on cold, you may have a faulty coolant temperature sensor. If it will get to normal operating temperature while sitting still, but starts cooling down when you drive, you have a thermostat failure - it's stuck open, and will need replacement.

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.
