Chyrsler Dodge 4.0L V6 Remanufactured Engine – 2007-2010 FWD

Description

Front-wheel-drive torque steer vibration and timing belt hydraulic actuator failure under 259 lb-ft sustained cargo hauling compromise commercial dispatch deadlines until precision line honing stabilizes camshaft journals inside this Chrysler 4.0L V6 Remanufactured Engine. Built for 2007 to 2010 front-wheel-drive fleet vans, this 24-valve SOHC aluminum platform pairs high stroke displacement with cross-bolted main bearing durability.

Featuring high-strength A319 cast aluminum construction, this 60-degree V6 block features 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 cross-bolted four-bolt main bearing caps. Forged powdered metal connecting rods carry flat-top hypereutectic pistons with anti-friction skirt coatings. Dry block weight equals 385 lbs with a 5.5-quart structural oil pan capacity.

Key Features of Chrysler 4.0L

Fleet operators buy Chrysler 4.0L long block engine units to minimize maintenance costs on regional transport vehicles. Detailed machine shop inspection procedures verify all bearing clearances before final crating for transport to maintenance hubs.

• Extended stroke crankshaft increases displacement to produce 259 lb-ft of continuous pulling torque.
• Single overhead camshafts actuate four valves per cylinder through center-pivot roller rocker arms.
• Cross-bolted four-bolt main bearing caps provide maximum bottom-end rigidity under sustained load.
• Multi-layer steel cylinder head gaskets withstand 195 PSI dynamic combustion strokes without failure.
• Chrysler 4.0L high-pressure 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 lash adjusters maintain zero valvetrain clearance across extended fleet operational hours.

High Stroke Front Drive Metrics

Normal operating oil pressure maintains 22 PSI at hot idle and 45 to 65 PSI at 2,500 RPM cruise. Engine coolant temperature regulates between 192°F and 205°F through standard thermostatic flow. Power output measures 251 continuous horsepower at 6,000 RPM, providing 259 lb-ft torque at 4,100 RPM. A 10.2:1 compression ratio yields 185 to 195 PSI cranking compression. Heat rejection across radiator circuits reaches 4,100 BTU/min under Severe Commercial Fleet duty cycles across heavy regional freight corridors.

Front Drive Transverse Driveline Specs

The rear crankshaft hub incorporates an 8-bolt flexplate pattern engineered for commercial 62TE transverse 6-speed automatic transaxles. Crankshaft snout measures 1.259 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.

Timing Belt SOHC Priming Protocols

Pre-lubricate oil circuits with an external pressure canister prior to first start to charge the hydraulic lifter galleries and rocker shafts. Fill cooling system with approved HOAT 50/50 mixture using vacuum cooling tools to prevent hot spots. Not engineered for supercharged racing applications, continuous marine salt water usage, or vehicles exceeding factory gross axle ratings.

• Inspect external accessory belt drive alignment and fluid levels each shift.
• Check timing belt hydraulic tensioner pin extension every 50 operating hours.
• Change crankcase motor oil and heavy spin-on filter every 4,000 miles.
