Diesel Motor Mechanic Cover Letter Template

Dear Hiring Manager, I’ve spent the last decade keeping heavy diesel engines on the road, and I know what it takes to get a machine back to work without the guesswork. In the last role, I rebuilt a cracked cylinder head on a fleet of 12 [Company Name] vehicles, cutting downtime by 28 hours per week and restoring reliability across the service fleet. I’m not chasing hero moments, just steady, practical fixes that let the team move forward. My hands-on approach covers fault diagnosis, dismantling and reassembly, parts replacement, and engine testing. I’m comfortable using diagnostic computers, cross-checking service manuals, and aligning work with roadworthiness standards. I pay attention to wear patterns, bolt torque, and clearance specs, so repairs hold up under load and vibration. There’s a story from a couple of months back that still sticks with me. A mid-life Cummins motor started losing power intermittently on a road train contract. I diagnosed a faulty turbo actuator, replaced the unit, and recalibrated the system. After road testing, the vehicle returned to service without repeat faults, and the workshop noted a clear improvement in overall engine response. I’m interested in contributing to [Company Name] and bringing my practical, no-nonsense approach to your diesel team. I’m available for a chat when it suits and can start soon if needed. Kind regards, [Your Name]
