Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Safety Precautions
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
- Route all wires and lines so that the original path is followed.
- Ensure sufficient clearance to all moving or hot components.
If special testing equipment is required during a road test, note the following:
- Testing and measuring instruments must be secured on the rear seat and operated by a second technician.
If the vehicle is involved in a collision while testing and measuring equipment is operated from the front passenger seat, the person sitting in that seat could be seriously injured when the airbag deploys.
To reduce the risk of personal injury and/or damage to the fuel injection and glow plug system, always observe the following:
- Only disconnect and reconnect wires for the glow plug and fuel injection systems including test leads when the ignition is turned off.
- Always turn the ignition off before disconnecting or connecting the battery. Failing to do so could damage the diesel direct injection system control module.
