Ford Mazda 2.3L L4 Remanufactured Engine – 1989-1994

Description

Command 100 horsepower and 2.3 liters of dyno-certified four-cylinder displacement while holding engine coolant temperatures below 195°F during grueling municipal delivery and compact utility routes inside this Ford 2.3L Lima Remanufactured Engine. Built for 1989 to 1994 commercial compact trucks, this OHC iron block engine features twin-plug distributorless ignition timing and a round-tooth timing belt drive.

Cast from high-density gray iron, this inline-four block features five main bearing bulkheads and an Ra 28 micro-inch deck surface finish. Internals include a nodular iron crankshaft supported by line-honed caps, forged steel connecting rods, and aluminum alloy pistons. Bores receive diamond plateau honing with a 45-degree angle. Dry block weight equals 305 lbs with a five-quart oil sump capacity.

Key Features of Ford 2.3L

Municipal fleet managers buy Ford 2.3L remanufactured engine platforms to keep compact vocational trucks operating without mechanical downtime. Experienced engine machinists align-hone each bearing saddle to eliminate parasitic friction under grueling regional haul conditions.

• Dual spark plugs per cylinder accelerate flame travel across shallow combustion chambers under load.
• Round-tooth timing belt drive profile minimizes tooth wear and prevents premature belt stripping.
• Cast iron cylinder block casting provides structural rigidity during continuous urban stop-and-go driving.
• Ford 2.3L high-volume oil pump maintains 45 PSI steady fluid volume to overhead valvetrain gear.
• Hydraulic lash adjusters maintain zero valvetrain clearance across extended fleet operational hours.
• Multi-layer head gaskets seal combustion pressures across extended operational duty hours.
• Diamond plateau cylinder honing provides rapid moly ring seat without cylinder bore burnishing.
• One-piece fluoroelastomer rear main seal locks motor oil inside the crankcase envelope.

Twin Plug Lima Operational Ratings

Engine oil pressure holds 18 to 22 PSI at hot curb idle and 40 to 55 PSI under loaded cruise conditions. Operating thermostat regulation maintains water temperature between 185°F and 200°F. Power production yields 100 continuous horsepower at 4,600 RPM and 135 lb-ft torque at 2,600 RPM. A 9.0:1 compression ratio maintains 155 to 165 PSI dynamic cranking compression. Radiator heat rejection reaches 2,800 BTU/min under Severe Commercial Fleet operation across metropolitan routes.

Twin Plug Lima Driveline Dimensions

The one-piece rear main seal crankshaft incorporates a 6-bolt flywheel flange pattern on a standard circular pitch. Front snout diameter measures 1.181 inches with a precision woodruff keyway for mechanical damper retention. Crankshaft thrust endplay checks out between 0.003 and 0.006 inches on dial indicators. Pilot bushing recess accommodates commercial manual and automatic transmission input shafts without binding.

Twin Plug Lima Engine Break In

Pre-lubricate oil galleries with an external pressure tank before initial ignition to coat all bearing surfaces and cam lobes. Fill crankcase with SAE 5W-30 synthetic blend lubricant and bleed cooling system air pockets under vacuum. Not engineered for marine salt water service, forced induction turbocharger systems exceeding 6 PSI boost, or gross vehicle weights exceeding 5,500 lbs.

• Inspect external engine hardware and fluid levels with exact attention each shift.
• Check twin coil pack wiring and spark plug wire insulation every 50 operating hours.
• Perform oil changes with approved motor lubricant every 3,000 miles.

Twin Plug Lima Commercial Warranty

Covered by a 3-Year / 100,000-Mile commercial fleet warranty covering structural block defects and internal parts. The reinforced shipping container contains the remanufactured long block engine, high-flow oil pump, oil pickup tube, complete installation gasket kit, spark plug seals, pre-lube instructions, and hot-test dyno reports.
