Maintenance Tips for Your GMC Typhoon's Turbo-charged Engine
Mid-sized SUVs such as the GMC Typhoon are diamonds in the rough. Despite its truck-like exterior, lowered suspension system, and hot-rod posture, this three-door SUV could go from 0-60mph in under 6 seconds. It can go head-to-head with well-known sports cars such as the Nissan 300ZX Turbo, Chevrolet Corvette, and the iconic Ferrari 348ts. The Typhoon's secret was its powerful 4.3-liter LB4 turbo-charged V6 engine, which also included a Garret Water & Air intercooler. It also featured a self-leveling suspension and an all-wheel drive system. If you happen to own one of these high-powered SUVs, here are maintenance tips to keep its iconic turbo-charged engine in top condition.
- Observe correct driving habits.
Your driving habits can affect the performance of your engine's turbo charger. Observing correct driving habits will help maximize its lifespan and performance. After starting your engine, wait for at least ten seconds before driving your SUV. This allows engine oil to reach the turbo charger and lubricate its parts. While driving, let the engine warm up before stepping on the gas pedal. Let your engine accelerate slowly and build up speed. Don't push it to reduce stress on the turbo charger. After a long journey, don't turn off the engine immediately. Give the turbo enough time to cool down to avoid permanent damage. Let the engine run idle for a minute or two before turning off the engine.
- Pick the right type of engine oil.
Engine oil is the lifeblood of any vehicle, including your mid-sized SUV. However, using cheap or low-grade oil won't help protect your engine's parts and its turbo charger. A typical turbo charger has many moving parts, which need proper lubrication. Without effective lubrication, its parts could rub against each other, which could lead to friction damage. Pick the right type of engine oil based on your manufacturer's recommendations. It should have the right viscosity to keep all moving parts properly lubricated. The right engine oil will ensure smooth engine and turbo charger operation.
- Clean your engine's fuel injectors.
Aside from using the right kind of engine oil and changing driving habits, maintaining the fuel system should also be prioritized during engine maintenance. Your mid-sized SUV is sensitive to irregularities and disruptions with its fuel supply. Aftermarket fuel injection cleaners can help you clean your engine's fuel injectors. Add them to every tank of fuel to ensure clean fuel while driving. Also, don't forget to change your vehicle's fuel filter every 4,000 miles. This will also ensure that only clean fuel goes through your engine's turbo charger.
- Inspect the turbo charger for possible leaks.
Over time, certain parts in your engine's turbo charger may develop small leaks, especially in its pressurized intake system. This system is responsible for releasing boost pressure to regulate the turbo system's power. Inspect these parts for leaks by spraying your engine's turbo-to-intake manifold duct coupling with soapy water. Do this while the engine is running to see if bubbles form around these areas. If you see bubbles forming around these couplings, have it examined by a mechanic for cracks or damage. These leaks should be dealt with immediately to avoid costly repair or replacement jobs.
Bad driving habits, oil problems, and neglecting basic maintenance procedures can ruin your GMC Typhoon's turbo-charged engine. Don't let your iconic SUV go to waste and take note of these simple tips.
GMC Typhoon: A Big and Powerful Supercar that Left a Mark
The GMC Typhoon was sold in the market from 1992 to 1993 only, but even if it was short-lived, the vehicle definitely made its mark, especially among SUV aficionados. This vehicle is basically a high-performance version of the GMC Jimmy SUV—a model that lasted from the 1990s until the early 2000s. Here’s a brief glimpse into the specs as well as the changes and transformations of the GMC Typhoon from its introduction to the market until its demise.
1991: Design and development
In 1991, six prototype units of the Typhoon were created by General Motors based on the GMC Jimmy SUV. However, when comparing the two models, the Typhoon noticeably had major differences with the Jimmy, especially with its exterior components.
1992: Initial release
The Typhoon was officially introduced to the market in 1992, and it was released alongside the GMC Syclone. Both SUVs shared a lot of features and characteristics with one another. For instance, they both featured the Mitsubishi TD06-17C/8 cm2 turbocharger in their systems. They were also equipped with a Garrett water/air intercooler in their 4.3 L LB4 V6 engines, intake manifolds, fuel systems, and exhaust manifolds. Both trucks were also manufactured in General Motor’s production plant in Troy, Michigan.
The GMC Typhoon was only made available as an all-wheel drive, and its 4.3 L LB4 V6 engine was known for its power. In fact, it boasted 0-60 mph acceleration in 5.3 seconds. It was also capable of running a quarter of a mile in just 14.1 seconds at 95 mph. And just like the GMC Syclone, it was also furnished with a 4L60 4-speed automatic transmission and a BorgWarner transfer case. This caused the torque of the vehicle to become split, making it more stable. But aside from its under-the-hood components, it was also memorable for having 245/50VR-16 Firestone Firehawk SVX tires on alloy wheels. It was also equipped with large air dams with bulging fog lights. And during its short, two-year run, it was sold and produced in several colors such as black, frost white, apple red, garnet red, raspberry metallic, bright teal, aspen blue, radar blue, royal blue metallic, and forest green metallic. However, among all these colors, the most popular one was the black model, which sold thousands of units.
1993: Upgrades and improvements
In 1993, more colors were added to the Typhoon’s lineup. And aside from being an all-wheel drive, the vehicle became known for carrying upgraded brakes and having sports modifications added to its standard suspension. It also had a self-leveling rear suspension, which owners enjoyed a lot. In the end, over 4,697 units of the GMC Typhoon were produced and sold in the market. It was not replaced by any specific GMC model, but it definitely made a lasting impression in the SUV segment.
