2014 Jeep Grand Cherokee 3.6L Engine Replacement Cost

A 2014 Jeep Grand Cherokee 3.6L engine replacement usually means a used Pentastar V6 or a remanufactured unit — used units run about $1,900–$2,600 for the part itself; remanufactured pricing is quoted per unit, so call for the current price on your VIN. The two failures that most often end in replacement are the oil filter housing leak and the rocker-arm tick.

Oil filter housing and cooler leaks The plastic oil filter housing and cooler assembly is the best-known Pentastar weakness. It cracks and leaks oil, often pooling in the valley and dripping onto the ground or the exhaust. Caught early it is a component repair; left alone, low oil can damage the engine.

Rocker-arm tick A ticking noise from the top of the engine that does not fade with temperature can mean worn rocker arms or lifters — the Pentastar's other well-documented failure. If the tick is confirmed internal and the cam is scored, replacement is usually the practical path.

Overheating from coolant loss Thermostat housing and water pump leaks are common at higher mileage. An engine that runs hot needs a cooling-system diagnosis first — replacing an engine will not cure overheating caused by a failed thermostat or pump.

Start with the remanufactured option if you plan to keep the vehicle. A remanufactured engine is fully disassembled, inspected, and rebuilt to specification with new wear components, and it is tested before it ships. It costs more than a used unit, but it arrives with the stronger warranty — up to 5 years with unlimited miles, parts and labor — and it corrects the wear that killed the original. A used engine is a pull from a donor vehicle: the lower-cost path, sensible when the rest of the vehicle is solid and you need it running again without a large outlay. Used units carry up to 5 years or 50,000 miles of parts-only coverage. Either way, confirm the VIN, the engine code, and 2WD versus 4WD before you order, and have a licensed shop do the install.

We back every engine we sell, and the two warranties are different in a way that matters when you choose. A remanufactured engine carries up to 5 years of coverage with unlimited miles (gasoline, non-commercial, 2001 and newer), parts and labor included, with labor reimbursed at $50 per hour per the Mitchell labor guide after an approved claim. A used engine carries up to 5 years or 50,000 miles, parts only, with no labor reimbursement. Both require installation by a Licensed Automotive Repair Facility, and used units must be installed within 14 business days of delivery with the heat tabs intact. Remanufactured units also carry a refundable core charge, returned when your old engine comes back to us.

Replacement is the right move when the failure is isolated to the engine and the rest of the vehicle is worth saving — solid body and frame, good tires, no major suspension or electrical issues. A quality used or remanufactured engine can extend the life of an otherwise good vehicle by years at a fraction of the cost of a replacement vehicle. Get an honest assessment first: if the vehicle also needs major work elsewhere, or the repair cost approaches the vehicle's value, the math changes. Proper diagnosis from a trusted mechanic is the essential first step — don't replace what doesn't need replacing, but don't pour repair money into an engine that is already mechanically compromised.
