SOURCE: How to change a water pump on a 1999 Buick Century 3100?

the water pump on the 3.1 isnt to hard to change ...

  1. Disconnect the negative battery cable.
  2. Partially drain the cooling system into a suitable container.
  3. Remove the drive belt guard.
  4. Loosen the water pump pulley bolts before removing the drive belt. This should help keep the pulley from turning as the bolts are loosened.

SOURCE: 1999 Buick Century thermostat question.

patience , and a 13 MM wrench , you gotta get your arms in there deep , that lower bolt does not need to come all the way off , the thermostat housing has a slot at the bottom for easier access , loosen it about 3.4 of the way and you can get the housing out , experience says a premium thermostat will give you grief trying to reinstall , get a regular duty thermostat .reverse procedure.

SOURCE: how do I change the fuel filter in a 1999 Buick Century Custom?

Philly, the fuel filter is attached to the frame in front of the gas tank, under the driver side of the car. You must relieve the pressure in the fuel line before you start, and it is also recommended that you disconnect the neg. battery cable. After disconnecting the neg. cable, remove the gas cap. Next, look under the hood on the fuel rail for a shrader valve (like the type on a bicycle tire). Place a rag under the valve, remove the cap, and press the valve in with a plastic pen to relieve the pressure in the line. You can now go under the car to remove the filter. You can disconnect the fuel lines easily with an inexpensive plastic disk made for this purpose (only a few $ for several sizes at a parts store). Be careful of fuel in the line that will drain out, no smoking or sparks during this procedure. Should be 1 bolt securing filter to frame. Note arrow on new filter, and install in the correct direction. Replace cap on shrader valve, put gas cap back on, reconnect battery cable. The low coolant light is probably a faulty sensor signaling that it's low, when it's actually ok. Look for wires coming from the reservoir bottle, you should be able to find the sensor at the end of the wires to replace it. If you change the fuel filter in a garage, leave the door open for air circulation, gas fumes can explode easily, having the door open will help dissipate the fumes.

It is in the side cover on the valve body. The transmission needs to be removed to access the solenoids.

Buick Century ECU location


The vehicle's Powertrain Control Module (PCM), is a powerful on-board computer that controls most powertrain related functions, hence its name. Earlier versions were often called the Engine Control Module (ECM) or Engine Control Unit (ECU) but as the computers have become more advanced and, as more and more demands have been placed on them to control more driveline functions, the computers have come to be called Powertrain Control Modules, more accurately reflecting its increased role in vehicle operations.

The PCM in your W-Body vehicle is located underhood, in front of the right strut tower near the engine coolant reservoir.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer. Thank you for using Fixya, and have a nice day.

Electronic power steering


It could be the electronic power steeirng module . With the gauges dropping out like that , the module could be bring down the data bus . Don't know how much you know about automotive electronic's an how the insturment cluster know's what speed to set speedo at an how full fuel gauge is an rpm on the tach .
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM calculates the vehicle speed based on the class 2 message indicating the wheel reference speed from the electronic brake control module (EBCM) if:
• The ECM/PCM detects a malfunction in the vehicle speed sensor circuit.
• The IPC detects a loss of class 2 communications with the ECM/PCM.
The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of class 2 communications with both the ECM/PCM.

012 GM Class II Communications

Checking the vehicle modules for DTC'S - diagnostic trouble codes is the first place to start .
The Power Steering Control Module (PSCM) receives a class 2 vehicle speed message from the Engine Control Module (ECM) via a class 2 serial data circuit. The PSCM uses this vehicle speed message, and other inputs, to determine the desired amount of steering assist.

DTC C0475
DTC C0476
DTC C0545

DTC C0900

your best bet ,take it to a qualified GM repair shop .
