- Change the fuel filters – Fuel filters are often taken for granted and overlooked in the maintenance schedule for diesel engines but letting these filters get clogged can lead to expensive consequences such as the damage of injectors and injection pumps
- Change out air filters – Keeping air filters around until they get clogged hurts mileage and makes the turbo work harder to deliver air to the engine.
- Changing fluids – Fluids that should be changed regularly include engine oil, coolant, transmission fluid, and power steering fluid.
- Warm the engine before heading out on the route – Engine parts warm up at their own pace, so have drivers warm the engines to allow oil to thin and lubricate the turbo and rest of the machinery properly.
- Pay attention to smoke coming from the engine – Black, white and blue smoke signify different issues with a diesel engine.
While a little smoke is normal in the cold, if smoke continues to be emitted when the engine is warm the bus should be taken in for service.
