Ford Mercury 2.5L V6 Remanufactured Engine – 1999-2000

Description

Command 170 horsepower and 2.5 liters of dyno-certified quad-cam displacement while holding engine coolant temperatures below 200°F during grueling municipal transport and commercial route operations inside this Ford 2.5L Duratec Remanufactured Engine. Built for 1999 to 2000 commercial platforms, this updated Duratec 25 engine features returnless fuel delivery, composite intake runners, and deep-skirt aluminum block architecture.

Featuring high-strength A319 cast aluminum construction, this 60-degree V6 block incorporates cast-in iron cylinder liners honed to an Ra 25 micro-inch deck finish. A micro-polished forged steel crankshaft spins on tri-metal bearings within an integrated lower bedplate. Forged powdered metal connecting rods carry flat-top hypereutectic pistons with anti-friction skirt coatings. Dry block weight equals 350 lbs with a 5.5-quart structural oil pan capacity.

Key Features of Ford 2.5L

Municipal fleet supervisors buy Ford 2.5L remanufactured engine platforms to keep municipal fleet sedans running without schedule disruptions. Each production unit undergoes line-boring and dynamic balancing to guarantee smooth operating performance across wide RPM bands.

• Returnless electronic fuel delivery system optimizes rail pressure under varying engine loads.
• Four overhead camshafts actuate four valves per cylinder to optimize intake charging efficiency.
• Structural cast aluminum lower bedplate ties all five main bearing caps together to stop crankcase twist.
• Multi-layer steel cylinder head gaskets withstand 190 PSI dynamic combustion strokes without failure.
• Ford 2.5L internal gerotor oil pump maintains 50 PSI cruising lubrication inside critical galleries.
• Cast-in iron cylinder liners provide long-term wear resistance inside a lightweight aluminum housing.
• Forged steel crankshaft incorporates induction-hardened fillets to eliminate rotational fatigue cracks.
• Hydraulic bucket tappets maintain zero valvetrain clearance across extended fleet operational hours.

Returnless Quad Cam Operational Ratings

Operating parameters require 20 PSI hot idle pressure and 45 to 60 PSI hot cruise pressure under load. Operating thermostat regulation maintains coolant heat between 192°F and 205°F during vocational service cycles. Dyno-verified output reaches 170 continuous horsepower at 6,250 RPM and 165 lb-ft torque at 4,250 RPM. A 9.7:1 compression ratio operates within 175 to 185 PSI cylinder pressure thresholds. Radiator circuits reject 3,600 BTU/min heat during severe commercial fleet operations across regional freight corridors.

Returnless Duratec Transaxle Driveline Specs

The rear crankshaft hub incorporates a 6-bolt flexplate pattern engineered for commercial CD4E automatic transaxles. Crankshaft snout measures 1.102 inches with precision keyways for dynamic balancer installation. Radial dial indicators confirm crankshaft endplay between 0.003 and 0.007 inches across all thrust surfaces. Precision-ground pilot hub bores seat automatic torque converters without radial runout.

Returnless Quad Cam Priming Boundaries

Pressurize the internal main oil gallery with 5.5 quarts of 5W-30 motor oil using an oil priming tank before turning the ignition key. Bleed cooling circuit air to prevent localized hot spots around exhaust ports. Not engineered for continuous marine vessel operation, alcohol-fueled race conversions, or boost levels over 6 PSI.

• Check cockpit oil pressure gauges and fluid sight glasses each shift.
• Inspect composite intake runner vacuum actuators every 50 operating hours.
• Drain crankcase engine oil and install fresh spin-on filter every 4,000 miles.

Returnless Quad Cam Warranty Details

Protected by an elite 3-Year / 100,000-Mile commercial fleet warranty covering parts and block manufacturing integrity. The reinforced transport crate includes the remanufactured long block engine, high-output oil pump, oil pickup tube, complete engine gasket set, installation guidelines, and dynamometer balance test reports.
