At Fraser Engines, every remanufactured engine is updated to meet or exceed the latest OEM Technical Service Bulletins (TSBs). That means recurring factory-identified issues are corrected before your engine ever leaves our facility—ensuring greater reliability, performance, and longevity.
Our process is far more than a simple rebuild. Every engine goes through a rigorous, multi-stage remanufacturing procedure that includes:
Complete Disassembly – Engine is fully torn down to the bare block for precise inspection.
Thorough Cleaning – Components are cleaned with high-pressure and chemical treatments to remove all oil, carbon, and debris.
Precision Inspection – Blocks, heads, crankshafts, rods, and other critical parts are magnafluxed, measured, and checked against OEM tolerances.
Block & Head Machining – Surfaces are decked, honed, and align-bored to exact factory specifications.
Component Replacement – Worn or out-of-tolerance parts are replaced with new OEM-quality or upgraded components (bearings, pistons, rings, lifters, gaskets, seals, oil pump, timing components, etc.).
TSB Updates Applied – Design improvements and manufacturer fixes are incorporated, eliminating known factory issues.
Precision Assembly – Engines are reassembled in a controlled environment, with exact torque specifications and clearances.
Testing & Quality Control – Each engine undergoes pressure testing, oil flow checks, and strict final inspections to ensure flawless performance.

When it comes to replacing your Chrysler, Dodge, or Jeep 3.7L engine, you have options. But here’s why choosing a Fraser remanufactured 3.7L is the smartest investment you can make:
A rebuilt engine only fixes the failed components. A Fraser remanufactured 3.7L engine goes through a complete tear-down, machining, and rebuild process. Every major wear component is replaced with new or upgraded parts — pistons, rings, bearings, seals, gaskets, oil pump, timing chains, guides, and tensioners.
The 3.7L V6 was widely used across Chrysler, Dodge, Jeep, and Ram vehicles, but it has several well-known issues:
Valve seat failures leading to misfires and compression loss
Dropped valves damaging pistons and cylinder heads
Timing chain and tensioner wear on higher-mileage units
Oil consumption and sludge buildup due to poor maintenance histories
At Fraser, we incorporate all factory TSB updates during remanufacturing. These issues are fixed before your engine ships, ensuring long-term reliability.
Every 3.7L engine we remanufacture undergoes a rigorous process that exceeds OEM standards:
Complete hot-tank and pressure cleaning
Magnaflux inspection for cracks and flaws
Cylinder block boring and honing to precise tolerances
Cylinder head resurfacing and full valve replacement
Crankshaft regrinding and balancing
New timing chains, guides, and tensioners installed
Final oil flow, compression, and leak-down testing
The result is a remanufactured 3.7L Chrysler/Dodge/Jeep engine that performs like new — or better.
Most Fraser remanufactured engines include a 4-Year / Unlimited Mileage Nationwide Warranty, with coverage that varies by unit. For maximum peace of mind, we also offer Fraser No-Fault Warranty programs:
3-Year No-Fault ($99.95) – $50/hr labor coverage
5-Year No-Fault ($495.00) – $95/hr labor coverage
10-Year No-Fault ($999.00) – $95/hr labor coverage
No-Fault means guaranteed replacement, no inspection, no hassle.
A remanufactured 3.7L engine from Fraser costs far less than a brand-new crate motor, while still delivering OEM-level performance and reliability. Plus, remanufacturing reduces waste — making it the eco-friendly choice for Chrysler, Dodge, Jeep, and Ram owners.
Our remanufactured 3.7L engines are direct-fit replacements for:
Jeep Liberty (2002–2012)
Jeep Grand Cherokee (2002–2010)

Fraser strongly recommends the remanufactured 3.7L as the best choice for performance, reliability, and long-term value.
A remanufactured engine is built with precision-machined surfaces, new piston rings, bearings, gaskets, seals, and updated components. The break-in process allows these components to properly seat and ensures long-term reliability. Failure to follow break-in procedures can cause:
Excessive oil consumption
Premature wear or scuffing
Overheating issues
Warranty denial for improper installation or neglect
Prime the Oil System – Before starting, pre-fill the oil filter and crank the engine without spark/fuel to build oil pressure.
Check Fluids – Fill with manufacturer-recommended oil (typically conventional, not synthetic, for break-in) and coolant.
First Start – Start the engine and immediately bring RPM to 1,500–2,000 for the first 15–20 minutes. This allows proper camshaft and lifter break-in while ensuring good oil splash.
Monitor Gauges – Watch oil pressure, coolant temperature, and listen for abnormal noises.
Inspect for Leaks – Shut down and check for oil, coolant, or fuel leaks before proceeding.
Avoid High RPM & Heavy Loads – Keep RPM under 3,500 and avoid towing, hauling, or aggressive driving.
Vary Engine Speed – Do not use cruise control; vary speeds to help piston rings seat properly.
Short Trips vs. Long Trips – Mix city and highway driving, but avoid extended idling or long highway trips at constant RPM.
Oil Change at 500 Miles – Drain the break-in oil, replace filter, and refill with fresh conventional oil. This removes metal particles from the seating process.
Continue varying engine speed.
Light to moderate loads are acceptable, but no full-throttle accelerations.
At 1,000 miles, perform a second oil and filter change.
Switch to high-quality synthetic or synthetic-blend oil if desired.
Normal driving, towing, and hauling can resume.
Maintain regular oil changes every 3,000–5,000 miles (conventional) or 5,000–7,500 miles (synthetic), or as recommended by Fraser Engines.
Always use premium filters (Fram Ultra, Wix, Mopar, Motorcraft, AC Delco, etc.).
Maintain proper cooling system function – replace thermostat, water pump, and radiator hoses during engine install.
Replace spark plugs, wires, and sensors if worn.
Use only manufacturer-approved coolant and oil specifications.
