VEGE Remanufactured 331F 2.4L 2389cc Car Truck Long Block Engine

Description

Bolt the VEGE Remanufactured 331F Car Truck Long Block Engine into chassis requiring dependable four-cylinder commercial pulling strength. This 2.4L 2389cc inline-4 car truck long block replacement produces 140HP across a durable cast iron block. Tall cylinder head height demands checking hood reinforcement clearance before securing final motor mount bolts to prevent chassis contact.

Heavy ASTM gray iron monoblock construction gives the VEGE 331F long block assembly structural rigidity under continuous commercial pulling cycles. The 5-main bearing bottom end supports a micro-polished forged steel crankshaft. Designed for 12V vehicle charging circuits, starter draw measures 155A during cold starts. Net dry weight lands at 320 lbs within an installation stance of 26in length by 23in width and 27in height. Sump oil capacity holds 4.5 quarts.

Key Features of VEGE Remanufactured 331F

Fleet maintenance supervisors buy VEGE Remanufactured 331F engines to complete an efficient commercial long block repower on light route pickups and utility service vans. This VEGE remanufactured long block provides direct replacement fitment for 2.4L four-cylinder commercial vehicle chassis.

• Five oversized main bearings absorb crankshaft torsional stress under continuous highway freight pulling.
• Hypereutectic pistons feature precision ground skirts for tight 0.0015in cylinder wall clearance.
• Hardened exhaust valve seats withstand high combustion temperatures during sustained highway grade climbs.
• Single overhead camshaft valvetrain optimizes intake air flow while eliminating valvetrain break-in wear.
• Heavy duty hydraulic timing chain tensioners prevent chain whip and maintain valve timing accuracy.
• High capacity oil pump supplies 48 PSI continuous pressure to main bearings and camshaft journals.
• Precision machined rear flange mates this 331F commercial core to original automatic or manual gearboxes.

Dyno Certified Thermal Diagnostics

Brake dynamometer trials establish this 331F long block engine produces 140HP at 5,200 RPM alongside 152 ft-lbs torque output at 3,600 RPM on standard commercial fuels. Oil pressure holds 46 PSI at operating temperature while coolant flow keeps operating temperatures at 182°F. Exhaust pyrometers register 1,180°F during full load step tests. Compression measurements verify 165 PSI across all 4 cylinders within 2% variance. Crankshaft journal runout checks below 0.0003in TIR on dial indicators.

Field Service Installation Bounds

Throttle cable pull mechanisms require 4 lbs force for smooth accelerator pedal action. Do not install this 2.4L four-cylinder car truck long block engine in passenger chassis requiring transverse drivetrain orientation without matching transaxle mounts. Fleet maintenance teams must check transmission torque converter pilot engagement depth before torquing bellhousing bolts to this 331F engine core.

• Change 5W-30 synthetic blend oil and filter every 250 operating hours or 3,500 miles.
• Inspect timing chain cover seal and front crankshaft damper every 500 operating hours.
• Torque intake and exhaust manifold bolts to 24 ft-lbs every 600 run hours.
