5 Things That Can Fail with A Chevrolet Turbo

Contamination in the Lubricating Oil

Contaminated Lube Oil is often a main cause of turbo failure. Inconsistent lube oil changes will often lead to an accumulation of carbon deposits in the lubricating oil. These soot deposits, subsequently, obstruct the little oil passages in the turbo, resulting in inadequate lubrication.

You can avoid this trouble by having your lubricating oil changed routinely. Also, make sure to complete engine maintenance at the recommended intervals. It is also essential to make use of the proper quality of high quality lubricating oil, as suggested in your owner’s manual.

Damaged Compressor Wheel

If a foreign object, like a little speck of debris, makes its way into the turbo and hits the compressor wheel, the damaged compressor wheel can cause your turbo to break fast. To avoid this kind of a catastrophe, you must ensure the air cleaner is effective and also does not enable any foreign particles to pass through.

Defective Exhaust Turbine

Engine Shut Down With Hot Turbo

A turbocharger normally is exceptionally warm after use. If you shut off the engine, the turbocharger will stop spinning. As a result, the turbine shaft comes to rest in one spot while exceptionally warm.

This heat can result in the shaft flexing somewhat, causing an imbalance in the turbo system. To prevent the effects of a hot stop, prevent shutting the engine down while it’s {hot}. Continue to run the engine at idle for a little while to allow the turbo to cool off while oil is streaming within it. When the engine has cooled down properly, you can shut your engine down.

Lengthen The Life Of Your Chevrolet Turbocharger

Chevrolet turbochargers are expensive. You don’t want to replace it really often. To avoid this need, you should do your best to safeguard it to make certain that it performs properly and holds up a very long time.

Below’s a few of the actions you can do to safeguard your turbo from destructive wear and tear:

Replace Your Oil Routinely

Turbochargers encompass moving elements that rotate at exceptionally high speeds. They also run under extreme temperatures and stress. It is essential, consequently, that they get an endless circulation of top quality engine oil. To make sure the turbocharger always operates properly, we’d recommend performing an oil change a minimum of every 5,000 miles.

Also, stay with the truck manufacturer’s recommendations for lube oil type and weight.

Remember to Allow Your Engine To Warm Up

Engine oil becomes thick when it is cold outside, which brings about an inadequate flow through the engine, subjecting the moving components, including the turbocharger, to higher danger of deterioration. So, just how do you lessen this danger?

Whenever you want to drive your truck when it is cold, you should remember the engine oil warm-up time. Be easy on the accelerator to stay clear of placing excessive pressure on the oil pump. You don’t want the pump to work extra hard to move the thick oil through the engine.

Thick oil can not lubricate the moving components effectively, which can result in destructive problems in the turbocharger system. It is recommended to be easy on the accelerator for at least the first ten minutes of driving with a cool engine.

If you live somewhere especially chilly, you may likewise consider having an oil pan heating unit installed.

Be Careful Not To Exceed The Limits Of Your Turbo

It is critical that you recognize the limits of your vehicle’s turbo. After that stay clear of exceeding that limitation. Whenever you are traveling, it is advisable to be gentle on the accelerator.

It holds true that turbos undergo strenuous testing and also are developed to last for a very long time. Nonetheless, being too aggressive with the accelerator can create stress on the turbo system as well as cause expensive effects. In addition to boosting the life-span of your turbocharger, gentle cruising can also help improve diesel mileage.

When Passing, Always Shift Down

A turbocharger can substantially increase your vehicle’s torque. However, it is not a great idea to allow the turbocharger system deal with 100% of the truck’s accelerative performance. Downshifting when passing is vital.

No matter the passing situation, downshifting into a lower gear could assist the turbocharger to hold up longer than it would if you rely totally on the turbocharger when passing.

Allow the Engine to Cool Before Shut Down

Turbos generate great deals of heat when spooling. If you shut the engine off right away after reaching your destination, the residual heat will lead to boiling oil inside the turbo. This can, in turn, cause the accumulation of carbon deposits, which can result in corrosion as well as premature engine wear.

Once you get to your destination, it is a good idea to leave the engine to run for a couple of minutes at idle to permit the turbocharger to cool off so you can switch the engine off without overheating the engine oil.

Prevent Blipping the Throttle Prior To Switching the Engine Off

When you push the fuel pedal, the turbines within the turbo will begin rotating. When you turn the engine down, the oil that lubricates the inside of the turbocharger will quit flowing. But, the turbine will keep on revolving.

This puts a lot of stress on the bearings, leading to rubbing and also an increase in temperature that creates serious troubles with the turbo. The very best method to lessen this danger is by permitting the engine to idle for a few minutes before turning off the engine.


Chevrolet turbos do an excellent job at increasing performance and promoting diesel economy. When your turbocharger begins to wear down, you’ll have to fix it or have it replaced. Two significant issues can trigger your turbocharger to break: leaks and also obstructions.

You will need a trustworthy diesel mechanic to examine your turbo for breaks and also make certain that the seals are functioning perfectly. Malfunctioning gaskets can cause your turbo to be inefficient when it pertains to pumping of air into the engine.

Obstructions, however, can be caused by a buildup of soot deposits or various other outside fragments leading to the engine getting insufficient air.

Another usual root cause of turbocharger failure is normal wear and tear. If you discover that your vehicle is lacking power and experiencing poor take-off power, or that you are adding a greater amount of lube oil than normal, might be a good time to start looking for replacement Chevrolet turbochargers.
