Bring Your Vehicle to J&S for Diesel Diagnostics

GMC and Chevy diesel engines power some of the country’s most capable trucks, but even these well-designed engines breakdown from time to time. When there’s something amiss with your GMC or Chevy engine, bring it to a service center that can provide accurate and complete diesel diagnostics and repair. 

Issues J&S Diesel’s Service Center Can Address

Loss of Power

Loss of power in a diesel engine may be caused by a number of issues. While an actual breakdown can cause loss of power, the issue is more likely due to poor diesel engine maintenance. For example, any of the following maintenance items can lead to power loss:

  • Clogged fuel filter
  • Clogged exhaust pipe
  • Dirty air filter
  • Dirty spark plugs

A service center that can perform complete diesel diagnostics will be able to determine exactly what’s causing your truck’s loss of power and address the issue.

Check Engine Light

A check engine light may come on for something as simple as a loose gas cap, or for a more serious issue like a failing airflow sensor. The first step in diagnosing this issue is running a specialized computer to pull up the exact code that’s triggering the check engine light. From here, a service center will know what probably needs maintenance or repair.

If your truck’s check engine light comes on, it’s particularly important to take the truck to a service center that specializes in diesel diagnostics. There are a few diesel-specific issues that can trigger this light, and a non-diesel service center won’t be as prepared to diagnose or address these issues. For example, a failing nitrogen oxide sensor or low diesel exhaust fluids could cause the check engine light to go on. These are issues that a non-diesel service center won’t normally fix.

Vehicle Stalling

When a diesel engine stalls, there’s likely a problem in the fuel system. This isn’t the only issue to check, though. A faulty fuel pump, poor fuel mixture and low fuel pressure can all cause a diesel engine to stall regularly or intermittently. Of course, the engine will stall if you run out of fuel, too. Other potential causes of stalling include a dead battery, a dirty air filter, clutch-related issues (on manual vehicles), a malfunctioning coolant sensor and loss of spark.  

A diesel service center will be able to determine which of these is causing your truck’s engine to cut out.
