Chrysler 3.6L Pentastar

JASPER® remanufactured Chrysler 3.6L Pentastar engines are built to meet, or exceed, OEM measured standards and have a 3 year/100,000 mile nationwide, transferable parts and labor warranty.  Click here for complete warranty information.  Our 3.6L Pentastar is a completely remanufactured engine with new wear parts, exacting tolerances, and live-run tested reliability.

The 3.6L Pentastar engine is commonly used in popular applications such as the Chrysler 200 and 300; Dodge Avenger, Challenger, Charger, Durango, and Grand Caravan; Jeep Grand Cherokee and Wrangler; and RAM 1500 and ProMaster.

The original 3.6L Pentastar engine is susceptible to issues that include: engine misfire (dropped valve seats, and valve guide wear), rod bearing failure, dry start-up and piston scuffing, oil consumption, piston slap, head gasket failure, engine oil contamination, low oil pressure, VVT failure and reliability.

JASPER remanufacturing advances include:

  • 100% replacement of early-style cylinder head valve seats with copper-infiltrated seats for improved heat dissipation and reduced wear.
  • 100% installation of NEW nitrided valves for improved heat resistance and reduced valve guide wear.
  • Valve guides are air-gauge tested to verify proper clearance between valve and guide.
  • 100% installation of NEW high-strength, Class 12.9 rod bolts to eliminate stretching, which can lead to bearing failure.
  • JASPER-designed piston with graphite coating helps prevent dry start-up and piston scuffing.
  • JASPER-designed pistons include 28% more major thrust bearing area to prevent dry start-up and piston scuffing.
  • Stronger JASPER-engineered pistons have a smooth, fully-machined, anodized crown which provides a thermal barrier and reduces carbon buildup.
  • JASPER’s piston design includes additional oil return holes (12 total) for increased oil drainback, to reduce oil consumption and prevent the oil rings from sticking.
  • JASPER installs a robust, two-piece 2.0mm oil ring for improved oil control.
  • JASPER piston rings include a steel top ring that has a PVD and DLC coating for longevity and less friction.
  • Additional accumulator groove is machined into the piston to decrease the pressure between the first and second ring land, preventing the upper (compression) ring from unsealing at higher RPMs.
  • 100% installation of synthetic, rubber-based PTFE (polytetrafluoroethylene) valve stem seals.
  • 100% torque plate honing of engine block, utilizing a torque plate and specially-designed, ARP2000® bolts, provides cylinder wall geometry that matches the cylinder head as a complete running assembly, for improved ring sealing.
  • JASPER-designed pistons include 20% more pin bearing area for better stability.
  • JASPER installs a thicker, PTFE (polytetrafluoroethylene) coated MLS (Multi-layer steel) head gasket.
  • Block and heads are resurfaced to a 50–150 Rz finish.
  • 100% installation of NEW engine oil cooler, and for ease of installation, assembly includes: oil temperature sensor, oil pressure sensor, knock sensor, and adapter harness.
  • 100% installation of a remanufactured oil pump that has been tested on JASPER-designed, stand-alone, oil pump testing equipment. Oil pressure and flow are measured with the solenoid on and off.
  • VVT’s are hydraulically tested using a state-of-the-art oil-controlled, test stand.
  • 100% live-run tested to verify proper compression, vacuum and oil pressure.
  • 100% tested intake and exhaust cam actuators to verify proper performance.
  • 100% black light leak tested to ensure the unit is leak free.
