Mazda 2.5L V6 Remanufactured Engine – 2000-2001

Description

Circulate high-pressure oil reserves and balance rotational mass to conquer severe stop-and-go fleet transit demands across punishing inner-city municipal corridors using the Mazda 2.5L KL Remanufactured Engine. Built for 2000 to 2001 applications, this 24-valve 60-degree V6 engine delivers balanced rotational smoothness and dependable stamina for commercial fleet transit operations.

High-strength die-cast aluminum block construction includes thin-wall cast-iron liners plateau-honed to Ra 25 micro-inch finishes. A micro-polished forged steel crankshaft rides within line-bored main bearing saddles, coupled to forged steel rods and lightweight hypereutectic aluminum pistons. Sump capacity measures five quarts, with an overall engine dry mass of 345 lbs.

Key Features of Mazda 2.5L KL

Municipal fleet managers buy Mazda 2.5L KL remanufactured engine assemblies to restore peak vehicle utilization rates. Automated cold-test spin verification ensures perfect valve seating and balanced internal compressions.

• Quad-cam 24-valve cylinder heads maximize charge air intake velocity across variable load ranges
• Variable resonance induction system broadens engine torque output across mid-range cruising speeds
• Multi-layer steel head gaskets resist thermal warping between aluminum heads and block deck
• Precision plateau honing creates optimum oil retention crosshatch for extended piston ring life
• High-flow internal trochoid oil pump provides 50 PSI pressure to protected bearing journals
• Compact 60-degree V6 architecture minimizes torsional vibrations without external balancer shafts
• Mazda 2.5L KL crate assemblies receive thorough ultrasonic testing across high-stress zones
• Precision-lapped intake and exhaust valves ensure tight combustion chamber seal under load

Mechanical Ratings Thermal Criteria

This V6 produces 170 horsepower at 6000 RPM and 165 lb-ft continuous torque at 4800 RPM using a 9.2:1 compression ratio. Cranking compression limits verify between 170 and 180 PSI across all cylinders. Coolant operating temperature ranges between 185°F and 200°F, with oil pressure holding 20 PSI at idle and 55 PSI at 3000 RPM. Thermal heat dissipation totals 3100 BTU per minute under Severe Commercial Fleet service.

Transaxle Interface Crankshaft Geometry

The rear crankshaft flange uses an eight-bolt flywheel mounting pattern with a 1.259-inch pilot hole dimension. Front crankshaft snout measures 1.181 inches with a keyway for timing drive location. Dial indicator measurement establishes crankshaft endplay within 0.0035 to 0.0075 inches.

Commissioning Rules Structural Exclusions

Technicians must pressure-fill internal oil galleries with break-in lubricant prior to turning the key. This engine is not engineered for aftermarket turbo kits exceeding 5 PSI boost, nitrous systems, or heavy commercial trailer towing exceeding vehicle chassis ratings.

• Check fluid levels and cooling lines each shift
• Change motor oil and filter every 4000 miles
• Inspect timing belt drive every twelve months
