If you are a truck driver, then you know that the turbocharger is an essential engine component. It increases the engine’s power and efficiency, allowing you to cover more miles in less time. However, a failing turbocharger can be a nightmare for any driver, especially if you’re on a tight delivery schedule.
Don’t panic! When you know what to do when your semi-truck turbo fails, you can take the right course of action and get everything back in working order.
Stay Calm and Pull Over
As soon as you notice something unusual with your semi-truck, remain composed and find a safe spot to pull over and park. Signs that something is wrong include the following:
- Sudden and significant loss of power
- Strange whining or grinding noises coming from the engine
- Excessive exhaust smoke
Safety should be your top priority, so activate your hazard lights to alert other drivers of your situation. Also, park away from traffic to protect yourself and your vehicle. Remaining calm and collected will help you think clearly and take the necessary steps without panicking.
Turn Off the Engine and Let It Cool Down
After safely parking, immediately turn off the engine to prevent further damage and avoid the risk of overheating. Allow the engine to cool for at least 15–20 minutes so that you don’t burn yourself when touching engine components. This cooling time also gives you a moment to breathe, assess the situation, and determine your next steps without the risk of worsening potential mechanical issues.
Check for Visible Damage or Leaks in the Turbo
Carefully inspect the turbocharger for visible signs of trouble, such as oil leaks, which could indicate a blown seal. Cracks might suggest structural damage, while strange noises could signify damage that requires urgent attention. Use a flashlight to examine the area around the turbocharger and associated piping to avoid overlooking subtle signs of wear, including hairline cracks or leaks.
Replace the Turbo if You Have a Spare
Having a spare turbo on hand can prove invaluable, especially if you’re in a remote area where immediate professional assistance is unavailable. You’ll need wrenches, screwdrivers, gaskets, and seals for the replacement. If you don’t know how to replace a turbocharger, leave that to the pros.
If you do know how to replace a turbo, take your time to consult the truck’s manual or an online guide to avoid mistakes. After swapping the components, secure all bolts and connections and test the new turbo by running the engine.
Call for Roadside Assistance or a Mechanic
If replacing the turbo yourself is not an option due to a lack of tools, expertise, or confidence, it’s best to contact a professional for help. Having contact information for reliable roadside assistance or a trusted mechanic stored in your phone or vehicle can help to get your truck back on the road. During the call, tell roadside assistance about the problems you’re experiencing and any visible damage. This information will speed up diagnosis and repairs.
Keep Track of Warning Lights or Error Codes on the Dash
Frequently return to the cabin and check out the dashboard for warning lights or error codes that may appear, such as the check engine light or turbo-related indicators. These alerts can help you understand the problem and prioritize the troubleshooting steps to address the issue. Note the codes or lights, and share them with the mechanic when they arrive. These will make diagnosing the issue more efficient and accurate.
Get a Diagnostic Tool To Read Codes and Identify Issues
Investing in a diagnostic tool can be incredibly helpful, as it allows you to read the error codes on your vehicle’s onboard computer yourself. This tool could potentially speed up the repair process by identifying the problem before professional help arrives. In some cases, you could reset minor issues or misfires yourself!
Inspect Connected Components
Thoroughly check the condition of components connected to the turbo, such as intercoolers, air filters, and hoses. These parts play a significant role in the turbo’s functionality by supporting airflow and maintaining pressure. Ensuring they are in optimal condition is important, as issues with these components can negatively affect the turbo’s performance and engine health. Look for clogs, cracks, or loose fittings that could be restricting airflow or pressure. When you know what to look for and how to clear the filters, you can prevent future performance problems.
Look for Loose Connections or Damaged Parts
Be sure to conduct a meticulous inspection for loose connections or visibly damaged parts around the turbo, such as seals or gaskets. Loose connections can lead to leaks or pressure loss and impair the turbo’s efficiency. Tighten loose connections promptly and replace damaged parts to prevent issues that could exacerbate the situation. Sometimes, a single loose bolt or clamp can cause significant problems if you don’t immediately take care of it.
The Importance of Regular Maintenance and Servicing
Establishing a routine maintenance schedule that includes regular checks on the turbo system is essential for keeping your semi-truck in good condition. Turbochargers are subject to wear and tear over time, but regular servicing can help you identify issues before they worsen. We recommend scheduling inspections for your vehicle’s turbo system every few months or at specific mileage intervals. Also, documenting each maintenance session can help you track the health of your vehicle’s turbocharger over time, making it easier to keep future problems from happening.
