FRASER ENGINES - 3.7L CHRYSLER, DODGE, JEEP ENGINE

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:

1. Built Better Than a Rebuilt Engine

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.

2. Updated to Solve Known Issues

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.

3. OEM Quality – Tested and Certified

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.

4. Strong Warranty Protection

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.

5. Affordable and Sustainable

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.

Fraser strongly recommends the remanufactured 3.7L as the best choice for performance, reliability, and long-term value.

Why Break-In Matters

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

Initial Start-Up (First 15–20 Minutes)

1. Prime the Oil System – Before starting, pre-fill the oil filter and crank the engine without spark/fuel to build oil pressure.

2. Check Fluids – Fill with manufacturer-recommended oil (typically conventional, not synthetic, for break-in) and coolant.

3. 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.

4. Monitor Gauges – Watch oil pressure, coolant temperature, and listen for abnormal noises.

5. Inspect for Leaks – Shut down and check for oil, coolant, or fuel leaks before proceeding.

First 500 Miles

• 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.

500–1,000 Miles

• 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.

After 1,000 Miles

• 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.

Additional Tips for Long Engine Life

• 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.
