Buick Parts Questions & Answers

  • Q: How to remove and install the starter for Buick Century and Regal?
    A: To remove and install the starter, begin by disconnecting the negative battery cable and raising the car on jackstands. Remove any starter braces or shields in the way, then remove the starter motor-to-engine bolts and allow the starter to drop down. Disconnect the solenoid wires and battery cable before removing the starter. To replace the solenoid, remove the starter from the vehicle and remove the screw and washer from the motor connector strap terminal. Remove the screws retaining the solenoid housing to the end frame assembly and twist the solenoid clockwise to remove the flange key from the keyway slot. Remove the solenoid assembly and install the new one by positioning the solenoid body on the drive housing and turning it counterclockwise to engage the flange key in the keyway slot. Install the screws to retain the solenoid housing to the end frame. For an overhaul, start by removing the starter from the vehicle and disconnecting the field coil straps from the solenoid. Remove the through-bolts to separate the commutator end frame, field frame assembly, drive housing, and armature assembly. On diesel starters, remove the insulator from the end frame and the shift lever pivot bolt. On 25 MT diesel starters, remove the center bearing screws and the drive gear housing from the armature shaft. Slide off the 2-piece thrust collar from the armature shaft and use a piece of pipe or socket to drive the retainer toward the snapring. Remove the snapring with pliers and slide off the retainer and starter drive. To reinstall, lubricate the armature shaft and install the starter drive and retainer. Place the snapring on the shaft and tap it into place. Slide the retainer and thrust collar onto the shaft and squeeze them together with pliers. Lubricate the drive housing bushing and engage the shift lever yoke with the clutch. Install the drive assembly into the drive gear housing and reassemble the remaining components. For brush replacement, disconnect the field coil from the motor solenoid terminal and remove the starter through bolts. Remove the commutator end frame and washer, then remove the field frame and armature assembly from the drive housing. Remove the brush holder pivot pin, brush springs, and brushes. Install the new brushes and reassemble the components in reverse order.
  • Q: How to check the condition of the balljoint for Buick Enclave,Chevrolet Traverse and GMC Acadia?
    A: To check the condition of the balljoint, start by raising the front of the vehicle and supporting it securely on jackstands. Apply the parking brake and block the rear wheels to prevent any rolling. Then, use a prybar to test for excessive movement between the balljoint and steering knuckle. Additionally, have an assistant move the top of the tire in and out while checking for any excessive movement at the balljoint stud nut. If any excessive movement is detected, further measurement with a dial indicator can be done for confirmation. For the replacement process, begin by loosening the wheel lug nuts, raising the front of the vehicle, and removing the wheel. Remove the control arm and drill out the rivets securing the balljoint. Clean the control arm and install the new balljoint using the supplied fasteners. Finally, reassemble the control arm.
  • Q: How to check Fuel Pump on Buick LaCrosse?
    A: The fuel pump check involves listening for the whirring sound made by the fuel pump when the ignition key is turned ON. If the pump does not come on, check the fuel pump fuse, relay, and wiring. If they all work, the fuel pump is likely defective. If the pump runs continuously, the PCM may be defective. Begin the engine and the gauge reading is compared to the proper pressure specifications. If the pressure is too low, there may be a faulty fuel inlet strainer or blockage in the fuel lines. If it is too high, replace the regulator. The key to the engine must be in the OFF position when checking the psi level. Any fuel leaks should be checked for and the system should be cleaned up.
