Automotive Heavy Mechanic Cover Letter Template

Dear Hiring Manager, Opening hook: I’ve spent years on diesels and heavy drive trains, keeping fleet uptime high by diagnosing faults quickly and getting engines back to work. In my last role I trimmed down repair times by around 15% with sharper fault finding and a disciplined approach to engine disassembly and reassembly, using electronic diagnostic gear to verify the fix. Skills alignment: I’m comfortable with diesel motors in trucks and buses, plus the mechanicals around transmissions, brakes, suspension and steering. I’ve used a range of diagnostic tools to interpret faults, and I’m practical about replacing worn parts by welding, bolting or soldering where needed. Routine maintenance, oil sampling and electrical system work are all in my wheelhouse, and I’ve trained apprentices alongside me to keep standards steady. Evidence story: At [Previous Company], a chronic fuel-injection issue would slow a line of engines and hit productivity. I traced intermittent faults with the scan tool, inspected EFI and cooling loops, and rebuilt the affected injector harness. After the fix, engine efficiency improved and hot-shot jobs moved through the workshop with fewer delays. It was a team effort, but the steady, methodical approach kept us on track rather than chasing false positives. Professional close: I’m keen to talk about how I can support [Company Name] with reliable diagnostics and solid on-site maintenance. I’m available for a chat this week or next to discuss the role in more detail. Kind regards, [Your Name]
