Buick is not only the oldest American auto manufacturer still active today – it is also one of the most accomplished car brands in the world. Ever since its introduction in 1899, Buick has been a pioneer in the world of luxury vehicles. The appealing interior, inspired by classic American living rooms, even brought Buick an affectionate nickname among buyers: “the moving couch”. These days, along with Cadillac, Buick represents the luxury segment of GM, America’s leading automaker. In addition to its groundbreaking technological innovations, Buick has always been known for its visually appealing, recognizable design.

Over the years, Buick has been changed a lot, but its popularity continues to grow, as the last few years turned out to be a huge success for the company. Both old and new Buick models clearly hold a special place in the hearts of car buyers around the world. Luckily for them, keeping a Buick of any age in spotless condition is easy with the selection of Buick replacement engine parts that you can purchase from our online store. From complete replacement engines and cylinder heads to gaskets, seals and plugs – you’re guaranteed to find anything you need to repair your Buick’s engine.

      Fan Belt? Alternator Belt? Serpentine Belt? Similarities and Differences
      Look up "fan belt" in any modern automotive dictionary, and you'll typically find a definition that reads, "An endless belt used to transmit power from a crankshaft-driven pulley to a pulley driving the fan, alternator, or other engine accessory. It is usually V-shaped in cross section with the point of the V fitting into a groove in the pulley".

      Performing a Basic Engine Tune Up
      This article will guide you through a generic tune up on most any car or light duty gasoline-powered vehicle built within the last 20 years or so. We will presume that you are tuning up your engine because it has reached the mileage or time point to do so, and that you are NOT performing a tune up to cure an engine performance defect. We make this distinction because not all running/performance issues will be solved via a simple tune up.

    Amazing Purchase
    I didn't intend to buy a valve cover. However when I saw a photo of this valve cover I was very impressed with this product and its finish. I made up mind to order it. This valve cover met all my expectations. It has great design and quality. I quickly installed it. Firstly, I wanted to fix it using T-bar bolts. Afterwards I decided to use hold downs and had no problems.
