Chrysler Dodge EDZ 2.4L L4 Remanufactured Engine – 2003

Description

A 9.5:1 compression ratio combined with 50 PSI hot cruise oil pressure outputs 150 continuous horsepower to propel gross payload laden commercial fleet transport runabouts using this Chrysler EDZ 2.4L Remanufactured Engine. Configured for 2003 commercial fleet vehicles, this 16-valve dual-overhead-camshaft iron block engine incorporates twin balance shafts and vehicle-specific sensor trigger configurations.

Featuring seasoned high-strength gray iron construction, this inline-four cylinder block incorporates dual balance shaft tunnels and an Ra 28 micro-inch deck surface finish. Internals include a nodular iron crankshaft supported by five main bearing bulkheads, forged powdered metal connecting rods, and aluminum alloy pistons. Bores receive diamond plateau honing with a 45-degree angle. Dry block weight equals 335 lbs with a 4.5-quart oil sump capacity.

Key Features of Chrysler EDZ

Commercial logistics operations buy Chrysler EDZ remanufactured engine platforms to keep regional delivery sedans and utility vehicles operating without mechanical delays. Experienced engine machinists align-hone each bearing saddle to eliminate parasitic friction under grueling regional transit conditions.

• Twin internal counter-rotating balance shafts cancel four-cylinder engine vibration harmonics.
• Dual overhead camshafts actuate four valves per cylinder to optimize intake charging efficiency.
• Multi-layer steel cylinder head gaskets withstand 180 PSI dynamic combustion strokes without failure.
• Cast iron block architecture provides exceptional rigidity under continuous urban stop-and-go driving.
• Chrysler EDZ high-pressure oil pump maintains 50 PSI steady fluid volume to overhead valvetrain gear.
• Hydraulic lash adjusters maintain constant valve clearance without manual mechanical adjustment.
• Diamond plateau cylinder honing provides rapid moly ring seat without cylinder bore burnishing.
• Fluoroelastomer front and rear crankshaft seals stop motor oil seepage past journal boundaries.

Dual Overhead Camshaft 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 190°F and 205°F during vocational service cycles. Dyno-verified output reaches 150 continuous horsepower at 5,200 RPM and 165 lb-ft torque at 4,000 RPM. A 9.5:1 compression ratio operates within 175 to 185 PSI cylinder pressure thresholds. Radiator circuits reject 3,100 BTU/min heat during severe commercial fleet operations across regional freight corridors.

Transverse Four Cylinder Driveline Specs

The one-piece rear main crankshaft flange carries a 4-bolt flexplate pattern engineered for commercial 41TE transverse automatic transaxles. Crankshaft snout measures 1.181 inches with precision keyways for dynamic balancer installation. Crankshaft endplay checks out between 0.003 and 0.007 inches using precision dial indicators. Torque converter pilot bore centers commercial automatic transaxle input shafts without friction.

Balance Shaft Four Cylinder Priming

Pressure prime all internal oil galleries with approved 5W-30 motor oil before initial crankcase ignition. Ensure the cooling system is vacuum bled to avoid air locks inside the cylinder head water jackets. Not engineered for high-boost turbocharger conversions exceeding 5 PSI, marine salt water use, or vehicles exceeding factory gross vehicle weight limits.

• Inspect external engine hardware and fluid levels with exact attention each shift.
• Check accessory drive belt alignment and tension every 50 operating hours.
• Replace crankcase motor oil and spin-on lubricant filter every 4,000 miles.
