Common Diesel Problems

Hard Starting

Glow plugs, fuel delivery, or compression issues. We diagnose and fix the root cause.

Loss of Power

Turbo problems, clogged fuel filter, or restricted exhaust (DPF). Your truck should pull strong.

Excessive Smoke

Black, white, or blue smoke indicates different problems. We identify and repair the cause.

Check Engine Light

Modern diesels have complex emissions systems. Professional diagnostics required.

Diesel Maintenance Schedule

Diesel engines need different maintenance than gas engines:

• Oil changes: Every 5,000-7,500 miles (diesel oil only)
• Fuel filter: Every 10,000-15,000 miles (critical!)
• Air filter: Check frequently, especially in dusty conditions
• DEF fluid: Top off regularly
• Coolant: Diesel engines run hotter - maintain properly

Why Diesel Expertise Matters

Diesel engines are fundamentally different from gasoline engines. They require:

• Different diagnostic tools and knowledge
• Understanding of turbochargers and boost systems
• Emissions system expertise (DPF, EGR, SCR)
• High-pressure fuel system knowledge
