Buick Rainier Guides

Looking back at the past design and quality of Buick parts, the vehicle is undoubtedly an expression of unique innovations. In its very first platform, Buick showed expandable land machine and sports car concept. David Dunbar Buick by then, the inventor of the vehicle's basis of Buick's success which is the overhead valve engine pioneered the construction of this vehicle. After several years in the industry, Buick Motor Company has become one of America's largest car makers, and in the hands of William C. Durant transformed as the General Motors, which by now turned to be the largest name in car making.

Buick descended to stay as a division under GM, and a marque that brought to life different types of platform that successfully gone through the market. One of the contemporary creations of Buick is the Rainier. Only in 2000 was its introduction to the market. Buick Rainier was then a mid-size sport utility vehicle. It has got complete Buick Rainier parts that were injected with the recent technology developed by that time.

Presently, Buick Rainier carries a more sophisticated engineering. Some of the performance parts were modified. Additional equipments were included in order to make the performance more refined. And modern accessories were made available for more comfortable ride experience, so as for cooler appearance. Basically, Rainier presents a concept that stands behind the shadows of Chevrolet Trailblazer EXT and GMC Envoy XL, Tahoe and Yukon. It's a Rainier that's available in two-wheel drive and four-wheel drive. The power is being generated from Standard 4.2-liter DOHC 24-valve inline-c6 Vortec 4200 engine and optional 5.3-liter OHV Vortec 5300 V8 engine which are both matched by a 4-speed automatic transmission system. The first engine kicks 275 horsepower and 275 lb-ft of torque, while the latter brings 300 horses and 330 lb-ft of torque.

Though it doesn't offer as much as the features present with its rivals, Rainier also features a whole lot of Buick Rainier parts which can truly be enjoyed by the drivers and passengers. But if you want to push the performance of your Rainier near the Trailblazer EXT's and Envoy XL's, what you have to do is pamper it with modified aftermarket Buick Rainier parts. Custom Buick Rainier parts would be the more ideal that OEM and factory Buick Rainier parts. These products are enriched with the substances that actually expand the capacity of the Buick Rainier to go further.

FAQs—Buick Rainier

I'm truly satisfied with the smooth ride that my Buick Rainier is giving me, and I want to keep it that way. How can I make sure of that?

Smooth ride can be attributed to a well-built suspension system. You have to make sure that every single part of the system is in its utmost condition. And that is possible with proper maintenance regimen. Regularly check the alignment of the parts to avoid swaying. Imbalance affects tire contact on the ground, thus the vehicle becomes unstable and risky at high speeds. Also keep an eye on worn spring bushings, damaged coil springs or spring bars, loose u-bolt, and problematic bearings because they can make the vehicle incessantly jolt even on paved roads. Not all causes of bumpy ride come from a problematic suspension system part, though.

High-risk leaning and pitching can be traced back to loose wheel knots, misaligned wheels, insufficient tire pressure, non-balanced tire size, and even improper brake adjustment. And so, thorough inspection is required if you want your Rainer to always ride smoothly. But when the task becomes too difficult for you to handle, get an expert's hand.

Buick Rainier is definitely one of the quietest SUVs I've ever driven. Lately, though, I'm disturbed with the increased noise that I hear from the inside. What could possibly cause it?

If the unusual noise is not coming from under the hood or the chassis, it could be the air conditioning system. If it is still not the cause, you will have to inspect your weatherstrippings. Worn or cracked weatherstrippings will let engine and wind noise in. And when you shift to higher gears, it will be intensified. Replace the whole part instead of simply fixing the affected portion. This way, you will not only bring back quietness in the cabin but also prevent rain water, moist, and outside temperatures from ruining your ride as seasons change. You may also install window air deflectors to help reduce wind noise.

My brakes are not responding well, although my pads are new and fluid is not leaking. How could that be?

There are a number of reasons why brakes become unresponsive, and topping the list is the quality of the brake pads. Substandard ones wear unevenly and fast. When brake fluid leaks go along, stopping becomes almost impossible. It is wise then to never undermine quality, not even a drop of leak. If unresponsiveness is caused by sticky brakes, you will have to check whether the brake linings have gone out of place or if the springs are too tight or too loose. This condition can actually lead to overheating. And since the brake fluid is flammable, your brakes are at risk of getting burnt. Furthermore, your wheels and tires are going to be affected, adding costly repair and replacement. Worse, your life is endangered. Also check if the brake master is problematic and prevents the fluid from returning even after releasing the pedal. The piston could have been stuck, thus affecting the brake shoes. So, realign, readjust, and replace as necessary.

A Series of Firsts in the Buick Rainier

Considered as the successor to the Oldsmobile Bravada, the Buick Rainier was a mid-size luxury SUV produced by General Motors from 2004 to 2007. This vehicle was also the first SUV sold under the Buick marque since the 1920s. Here’s a quick look at the Buick Rainier and its short but solid run.

Design and development

Though the Buick Rainier looked much like the Oldsmobile Bravada—save for its front fasica—there are a lot of firsts that can be found in this vehicle. For instance, it’s the first body-on-frame, V8 engine-powered, rear-wheel drive Buick since the 1996 Roadmaster. It was also the first Buick model to have the QuietTuning sound insulation feature, which gave the vehicle sound dampening features infused in its design. For instance, the hood and the firewall were furnished with thick, sound-absorbing pads and the vehicle also had triple door seals and acoustic laminate glass.

The GMT360 platform

The Buick Rainier was made available to the market in one configuration only, and it was built to carry five passengers comfortably. It shared the GMT360 platform with five other vehicles—the Oldsmobile Bravada (its predecessor), Chevrolet TrailBlazer, GMC Envoy, Isuzu Ascender, and Saab 9-7X. The 360 platform replaced the GMT330, but it shared nothing with its predecessor. It featured new technology and was notable for its hydroformed frame rails and independent front suspension.

Powertrain

Like all the other vehicles created under the GMT360 platform, the Buick Rainier was only made available with a 4-speed automatic transmission. Buyers were also given a choice between two kinds of engines. The first one was a 4.2 L Vortec I6 engine, which had its cylinders arranged in a straight line along the crankcase. The second one was a 5.3 L Vortec V8 engine, which packed a punch in terms of power.

CXL trim

In 2007, Buick came up with a special CXL trim for the Rainier and this served as the upscale model for the vehicle. This Rainier CXL was furnished with a superb sound system, thanks to its Bose stereo and XM Satellite radio.

Last year

2007 was the Buick Rainier’s last year in production. And for this final year model, the brand threw in several features in the vehicle. For instance, it was made available in the upscale CXL trim, which was packed with luxurious features. The Rainier was also offered in an all wheel drive option and it was also furnished with a standard rear air suspension. It was also equipped with several other features like the OnStar directions and connections for navigational purposes, a Standard StabiliTrak, and a heads-up display, which projected the speed of the vehicle as well as other important information on the windshield. The following year in 2008, the Rainier was finally replaced by the Buick Enclave, which was a brand-new crossover SUV.
