You should bring your vehicle to our shop if:

• There's Colored Smoke - All vehicles produce some exhaust, but a diesel engine can produce unusually colored smoke that will alert a mechanic to mechanical problems. Black smoke, for example, typically means the motor is receiving too much fuel and not enough air. This issue often results from a faulty injector or a clogged air cleaner. White smoke indicates the combustion chamber isn’t producing enough heat. Fuel containing water often causes this. Blue smoke is usually a sign the vehicle is burning engine oil because of a leaking turbocharger seal. When this happens, oil may seep into the intake and exhaust system, where the truck burns it like fuel.
• Your Engine Is Making Sounds - During a tune-up, repair professionals investigate any unusual knocking, banging, or pinging sounds from the engine. An expert diesel mechanic in Superior, WI will often use a process called a diesel purge to discover the problem. They run a special lubricant through the system, which allows the technician to isolate the noise and diagnose the problem more accurately.
• You Have Difficulty Starting - Several issues can prevent a diesel engine from starting. These include simple problems like dead batteries and more complicated repairs like bad fuel lines or burned-out glow plugs. The range of potential causes makes it time-consuming to attempt solving starting issues yourself. Obtain a general tune-up to get to the bottom of the failure efficiently.

If you notice any of the above warning signs, stop by today for service from the diesel mechanic Superior, WI relies on most.
