When You See Smoke, Call Us

When truck owners in Nappanee need a diesel repair shop, they can depend on Locke Auto and Diesel Repair. Diesel engines are durable, but excessive wear and tear can take a toll, and when your truck needs TLC, it sends smoke signals. A defective fuel injector, injector pump, or the need for an EGR valve repair or cleaning can cause an incorrect air/fuel mixture resulting in the engine running rich. This causes back smoke and should be addressed before more harm is done. Burning engine oil creates blue smoke and could be due to damaged or worn-out valve guides/seals or piston rings and should be considered an emergency. Finally, white smoke indicates coolant is leaking into the engine’s combustion chamber, which could cause overheating, so you should drive right to our diesel repair shop at 28699 County Road 50 Nappanee, IN 46550 for service. If you see smoke or notice engine soot buildup, it’s time to visit the friendly team at Locke Performance. We’ll work diligently to identify the problem, fix it quickly, then back our work with a 36-month/36,000-mile warranty to keep your stress at bay. Our shop is equipped for Duramax, Powerstroke, and Cummins repair services. When you choose our diesel repair shop, you know your truck will receive our undivided attention.
