Diesel engine servicing includes an oil change, inspection of the glow plugs, examination of the gaskets and attachment bolts and cleaning or replacement of the fuel and air filters. Regular maintenance is essential for vehicle safety, engine longevity and fuel efficiency. CarsDirect also recommends topping off each fill-up with a bottle of purifying diesel engine treatment, which prevents accumulation of sediments and impurities.
According to CarsDirect, most aspects of regularly scheduled diesel engine maintenance are simple, easy and do not require professional attention. It is critically important, however, to observe the following safety precautions while working on a diesel engine.
Engine fluids become extremely hot while the engine is running. The only way to avoid the risk of scalding and chemical burns is to wait for the engine to cool before servicing begins. CarsDirect cautions against performing any work on a running engine. It is also important to thoroughly stabilize the engine before removing any bolts, nuts and other support hardware. Falling engines cause potentially lethal human injuries and irreparable engine damage.
Diesel engine bolts endure extreme thermal and mechanical operating conditions. Checking and re-tightening these bolts is an essential element of every servicing session. Automotive Troubleshooting Secrets recommends checking the bolts at regular intervals between servicing appointments. This reduces the risk of engine damage caused by failed bolts.
