When people talk about the longest-lived automobile nameplates in the United States, one of those which inevitably surfaces is the one called GMC Suburban. The GMC Suburban is a large sports utility vehicle best described as an all-steel suburban carryall. The GMC Suburban is also one of the largest sports utility vehicles in the market. It has a maximum seating capacity of nine.
The GMC Suburban is the brainchild of the General Motors Corporation. Introduced way back in 1936, it was a vehicle based on a commercial panel truck. Instead of having a huge, windowless cargo area, however, the vehicle possessed a large passenger compartment. Two doors as well as a two-piece tailgate adorned the exterior of the vehicle.
From 1941 to 1946, GMC Suburban parts like bullet-shaped headlights manifested themselves on the facade of the GMC Suburban. General Motors also endowed the vehicle with an inline six engine capable of generating 93 horsepower. 1947 saw the GMC Suburban having flush-mounted headlights, wider grille and passenger compartment. The Hydra-Matic automatic transmission was also introduced to the GMC Suburban around this time of its existence.
Over the years, the GMC Suburban saw many changes and innovations, most of which were made possible in order to give the vehicle an edge over its competitors. It was something General Motor succeeded in actually doing. Splendid paraphernalia like wrap-around windshields, hooded headlights, jet pods, foot-operated parking brakes and tilt steering wheels were introduced as parts of the vehicle in a succession of years. This made the GMC Suburban one of the most sophisticated sports utility vehicles in the market as far as such features are concerned.
The GMC Suburbans of today have continued to uphold the character original GMC Suburban vehicles have been known for. Although they have seen numerous face lifts and makeovers over the years, they continue to carry the essence of what a true-blue GMC Suburban should actually be.
My GMC Suburban is consuming too much oil. What's the problem with it?
Most vehicles, especially the new engines of today, normally consume approximately half a quart of engine oil every 3,000 to 5,000 miles. As the vehicle ages, it's normal that the oil consumption goes up. However, if it is using up too much engine oil, this should cause concern. One common sign that the engine is using up too much is oil is if the exhaust is emitting blue smoke. A lot of vehicle problems can arise from too much burning of oil like damaging the spark plugs, oxygen sensors, and the catalytic converter. Not only that, it can also damage the whole engine.
The most common causes of high engine oil consumption are worn or faulty valve guides and piston rings. If the clearance between the valve guides and stems is too far or if the valve guide seals are already worn out, damaged, or not properly installed, engine oil will be sucked down to the guides and into the cylinders. Compression in the engine is still possible, but you're going to have to refill the engine oil often. It's a different story if the problem is caused by faulty or worn piston rings as the engine will have low compression.
This problem can only be fixed if the worn-out or damaged parts are replaced with new ones. If you are not knowledgeable in replacing the broken parts, it is best to seek the help of a professional mechanic.
There's a knocking noise coming from my engine when I start my GMC Suburban. Am I in trouble? What's causing it?
It's a big YES. If you hear a knocking noise coming from your vehicle's engine, you should be worried. Your engine is made up of various moving parts and if one or more fail, you can start to hear a knocking sound coming from inside it. The probable points of failure can come from faulty big end bearings, damaged engine oil pump, low engine oil pressure, broken valves hitting the pistons, and so on. When you hear the knocking noise, you should pull over immediately and check the engine oil, or it will be wise not to use the vehicle and have it towed and brought to a service center. If you continue to drive while hearing the knocking sound, your engine can get damaged and the damage may be irreparable.
I'm having trouble starting my vehicle. What's causing it?
If you are having trouble starting your vehicle, you should first check your battery if it is still working properly. Make sure that it is still charged. If not, you should have it charged. If it is already more than five years old, you should have it replaced as it might be already dead. However, if the battery is still okay, you should start checking the ignition system and its components. The problem can be coming from faulty spark plugs and wirings. Make sure that the spark plugs and wirings are working properly.
