The Buick Rainier is a mid-size SUV that first saw the world in 2003 and managed to stay in production up to 2007. Featuring a conventional body-on-frame construction and rear-wheel drive (all-wheel drive was optional), this capable and functional SUV was a good choice for those who wanted to get high cargo capacity, comfort, and practicality. When it comes to the engine, the Rainier offered a 4.2L I6 or 5.3L V8 engine mated to a 4-speed automatic transmission. Needless to say, these engines are powerful and require a fairly large amount of fuel, so engineers implemented several emission control systems to make the motors more eco-friendly.
Traditionally for more or less modern gasoline engines, such systems include positive crankcase ventilation, catalytic converter, EGR, and EVAP system controlling gasoline evaporation in the fuel tank. The designs of these systems vary in different models, but the working principle is mainly the same. Also, some of their parts require servicing or replacement over time. If you need high-quality Buick Rainier emission control parts, browse our online catalog. Here you will find a large assortment of products sorted by categories and model years. Place your order, and our professional team will ship the required replacement parts to your address.
