In the course of time, Buick has come up with new ideas like quiet tuning and driver-oriented features. The brand blended tradition with newer upgrades that fit modern lifestyles. Buick also displayed the bold Wildcat EV concept in 2022, showing its future design and all-electric direction. Buick continues with its long, responsible history and stylish designs.

Trust is Buick's advantage. The precise fuel injector brings easy starts and smooth passing. A high-strength subframe keeps the cabin quiet and straight over bumps. The headlamp assembly makes night driving clear and low stress. A tight, leak-free exhaust manifold keeps torque ready without harshness or fumes. Choose genuine Buick OEM parts to keep that calm feel. The factory fit prevents rattles before they begin and withstands performance in summer heat and winter cold.

Buick Parts Questions & Answers

  • Q: How to service and repair the Brake Master Cylinder on Buick LeSabre?
    A: Insert safe fittings over all the ports first and ensure they will not harm the seal valleys. Securely support the master cylinder at its mounting points to prevent warping while using the hoses to insert new fluid into its reservoir. Use delco supreme ii brake fluid gm p/n 12377967 or dot 3 equivalent parts to avoid damage to rubber components in the hydraulic system since water reduces boiling point and petroleum-based fluids swell them. Place a new supply of delco supreme ii brake fluid gm p/n 12377967 into the reservoir and push the cylinders down to their bottom positions with a smooth rod to prevent damage to internal parts. Depress then release the pistons repeatedly until the port lets fluid flow freely without air bubbles through it.
  • Q: How to replace the Cam Gear on Bank 1 (Right Side) Exhaust on Buick Enclave?
    A: You need to remove both lower Intake Manifold and the right camshaft cover to access the bank 1 exhaust camshaft position actuator. Untuck both the right camshaft position sensors before you remove the sensor actuator solenoids. When you rotate the crankshaft balancer bolt clockwise one turn and turn the balancer until the camshafts align parallel to the camshaft cover rail. Paint a stick onto the Timing Chain links and adjacent teeth of both the intake and exhaust camshaft position actuators before placing them on the baseplate. To create gap space between the actuator parts activate the open end wrench while moving the camshafts toward each other. Slide the en-48313 Timing Chain retention tool (EN-48313) legs backward by unscrewing it then position this tool between the camshaft actuators close to the Cylinder Head. Adjust the en-48313 moving control by turning the t-handle clockwise until the release feet tap the Timing Chain and center themselves in a link pocket to stop movement. First attach the en-48313 then expand the t-handle with an open end wrench. After installing the en-48313 in place, put an open end wrench on the actuator bolt to stop engine rotation before unwinding the right exhaust camshaft position actuator bolt and removing both parts. If removing both actuator parts, let the Timing Chain drop over the en-48313. Place the exhaust camshaft actuator alignment mark on its Timing Chain reference marks to match the marks you made during removal. Adjust the intake camshaft actuator alignment mark at the same time. Connect the exhaust camshaft actuator to its position on the camshaft before lightly tightening the installation bolt and taking out the en-48313. Secure the right exhaust camshaft position actuator bolt to 58 n.m (43 lb ft) and put back the right intake and exhaust camshaft position actuator solenoids then install right intake and exhaust camshaft position sensors followed by the right camshaft cover and lower Intake Manifold.
  • Q: How to replace a spark plug safely and correctly on Buick LaCrosse?
    A: The first step to replace a Spark Plug involves removing ignition coils followed by appropriate safety equipment including safety glasses along with compressed air precautions. Clear the Spark Plug recess area to stop dirt along with foreign debris from entering the cylinder block so it does not damage engine parts or soil the threads. A thread chaser should be used to remove contaminants touching the threads. The air compressor should be used to clean Spark Plug cavity while waiting for the engine temperature to drop to prevent thread locking during Spark Plug removal. The new Spark Plug installation requires using only vehicle-specified plugs that match the required temperature range since using incorrect plugs could cause severe engine damage. A round feeler gauge should measure the gap of new and reconditioned spark plugs to verify correct gap size according to specifications. Placing the Spark Plug thread into the Cylinder Head should be easy while making sure it reaches full seating using a thread chaser to prevent thread damage or overheating from improper seating or cross-threading. Follow installation of the Spark Plug by tightening it to 20 nm (15 lb ft) before putting back the Ignition Coil(s).
  • Q: How to replace a water pump on Buick Regal?
    A: Draining the cooling system and relocating the accessory wiring junction block is the first step to replace the Water Pump. Start working by first detaching the Water Pump Pulley bolts, then the Drive Belt, uninstalling both the Water Pump bolts and pulley from the engine. Move the Power Steering Pump aside while taking out its retention bolts. Then unfasten the Water Pump bolts followed by the Water Pump itself. Pick out the Water Pump Gasket and examine and prepare the parts where it meets. Set the Water Pump on its gasket and bolt the long Water Pump bolts to 34 nm while tightening the short Water Pump bolts to 22 nm. Fasten the Water Pump Pulley with a torque of 13 nm. Restore the Power Steering Pump unit alongside Drive Belt and accessory wiring before filling the cooling system.
