Diesel Truck Engine Repair in Phoenix, AZ

Heavy-Duty Engine Repair in Phoenix

The engine is the most expensive component on your truck, so an accurate diagnosis matters. Emergency Roadside Truck & Trailer Repair repairs heavy-duty diesel engines at our shop at 315 E Pioneer St and diagnoses engine problems on-site with our mobile mechanics. We read the codes, test the system and explain the repair before any work starts.

Engine Repairs We Perform

• Turbochargers and boost leaks.
• Fuel injectors and fuel system repairs.
• Water pumps, thermostats and cooling components (coolant system repair).
• Belts, tensioners and pulleys.
• Oil leaks, gaskets and seals.
• EGR valves and coolers (EGR repair).
• Sensors, wiring and ECM faults.
• Engine brake adjustments and repairs.

Engine Symptoms Not to Ignore

Rising coolant temperature, oil pressure warnings, white or blue smoke and knocking noises can turn into catastrophic engine damage if the truck keeps running. Pull over safely and call us — a small repair today is far cheaper than an engine replacement tomorrow.

In-Shop vs. On-Site Engine Repairs

Sensors, belts, hoses, many turbo and fuel system repairs can often be done where the truck is parked. Repairs that require removing major components — cylinder heads, internal engine work or large leaks behind the engine — are done in our Phoenix shop where we have the equipment and space. We’ll tell you which applies after the diagnosis.

Protect Your Engine

Keep coolant at the correct level and mix, change oil and filters on schedule, replace air filters on dusty routes, and address warning lights promptly. Most major engine failures start as a small problem that was ignored.
