Left Remanufactured Chrysler Dodge Jeep 3.7L V6 Cylinder Head 2002-2004

Remanufactured Chrysler Dodge Jeep 3.7L V6 Left Cylinder Head (2002–2004)

Premium OEM-Quality Replacement for 3.7L V6 Engines

Restore your engine’s peak compression and thermal efficiency with this professionally remanufactured left-hand (LH) driver-side cylinder head, specifically engineered for the 2002–2004 Chrysler, Dodge, and Jeep 3.7L SOHC PowerTech V6 engine series. Utilizing a high-strength aluminum alloy, each unit is precision-machined to meet or exceed original equipment (OE) dimensional tolerances, ensuring a superior head gasket seal and optimal volumetric efficiency for the LH cylinder bank.

Every cylinder head undergoes a rigorous multi-stage remanufacturing protocol—including ultrasonic cleaning, precision deck resurfacing, and high-pressure leak testing—to eliminate common failure points such as valve seat drop or cooling passage obstructions inherent to early 3.7L castings. This unit is designed to correct common “misfire” codes and restore the factory-spec performance required for reliable daily operation. Whether you are performing a top-end overhaul on a Jeep Liberty, Dodge Ram 1500, or Dodge Dakota, this remanufactured LH head provides the structural integrity and cooling capacity required to regain your 3.7L V6’s original reliability.

🛠️ In-House Machining Process

• Cleaning: Fully disassembled and thermally cleaned.
• Soda Blasted: Castings are blasted with Sodium Bicarbonate. Because baking soda is water-soluble, there is zero risk of abrasive media clogging oil passages.
• Pressure Testing: Tested to 60 PSI to ensure no cracks or porosity leaks.
• Surfacing: All heads are resurfaced on our Rottler S85A for a precision gasket-sealing surface.
• Valve Job: Multi-angle valve job performed; every port is Vacuum Tested to ensure valves are seated 100% airtight.
