Our skilled technicians are highly experienced in advanced diagnostics, accurately pinpointing problems and performing long-lasting truck repairs. From minor adjustments to major repairs, we deliver exceptional service to reduce downtime and extend your engine's life.
Diesel Engine Parts Replacement
When engine components fail or wear out, replacement is critical. We supply and install high-quality parts for commercial vehicles to restore truck performance and reliability. We recommend regular maintenance to avoid costly repairs down the line and keep your vehicles in optimal condition. As part of our complete engine maintenance services, we replace:
- Block
- Pistons

- Valves

- Camshaft
- Connecting rods

Complete Engine Rebuilds
When major internal damage or high mileage affects performance, a complete engine rebuild can be the most cost-effective solution for many vehicles. Rather than replacing the entire engine, rebuilding restores critical components to OEM specifications while preserving your existing engine block and configuration.
Dieseltech handles full diesel engine rebuilds for commercial vehicles in Coquitlam. A rebuild typically involves complete disassembly, detailed inspection, machining as required, and replacement of worn components such as pistons, bearings, seals, gaskets, and other internal parts. Rebuilding often makes more financial sense than installing a new engine.
Diesel Engine Maintenance
Your drivers count on their vehicles to run their best. Routine diesel engine maintenance is essential for preventing breakdowns on the road. Our team provides maintenance services that include engine system checks, oil changes and filter changes, fluid top-ups and replacements, cooling system inspections, fuel system testing, belt and hose inspections, and performance diagnostics.

An illuminated check engine light indicates a fault within your engine or emissions system.
Excessive Smoke
Black, white, or blue exhaust smoke can point to fuel imbalance, oil burning, or coolant issues.

Types of Diesel Engines We Service

2-Stroke Diesel Engine
Common in older diesel trucks, 2-stroke diesel engines complete a power cycle in two piston strokes, delivering high power output with a simpler mechanical design. They are often found in older heavy-duty applications and vocational trucks. While durable, they require specialized knowledge for proper servicing and tuning. If you’re searching for diesel engine repair near me for a 2-stroke engine, our technicians have the experience to maintain and repair these legacy systems.
4-Stroke Diesel Engine
Used in most modern diesel trucks, 4-stroke engines complete the combustion cycle in four stages: intake, compression, power, and exhaust. They are more fuel-efficient, produce lower emissions, and have improved longevity compared to 2-stroke designs. Found in today’s highway tractors, fleet vehicles, and commercial transport trucks.
