⚠️ Important Warranty Restriction

Use of TRD Equipment VOIDS Warranty: This engine is remanufactured strictly to naturally aspirated OEM specifications. The installation of forced induction systems, including TRD Superchargers or aftermarket performance tuners, alters factory cylinder pressures and operating temperatures, immediately voiding the up to 7-year / 1-million-mile warranty protection.

Why Choose Our Toyota 1GRFE Remanufactured Engine?

Sourcing a salvage yard V6 means inheriting someone else’s skipped oil changes or stretched timing chains. A completely remanufactured long block resets the clock to zero hours. The stringent build protocol for each Toyota 1GRFE Remanufactured Engine includes:

1. Thermal Cleaning & Disassembly

The entire aluminum V6 block is fully disassembled and thermally cleaned in specialized ovens to safely lift away hardened oil varnish, carbon scale, and stubborn coolant residues.

2. Magnaflux Structural Inspection

Utilizing advanced magnetic particle and dye penetrant testing, the aluminum blocks and cylinder heads are scrutinized for microscopic stress fractures that could cause long-term failure under towing loads.

3. Precision CNC Surface Machining

All deck surfaces on the engine block and cylinder heads are CNC machined to exact micro-inch finishes, guaranteeing a perfectly flat, unyielding seal for the multi-layer head gaskets.

4. 100% Brand-New Wear Parts

Reassembled with all-new main bearings, pistons, rings, lifters, high-flow oil pump, Viton™ valve seals, freeze plugs, galley plugs, and a completely new timing chain assembly featuring upgraded tensioners.

Automated SIM Testing Protocol

Reliability is non-negotiable for a truck powertrain. Before securing the crate for freight transit, every Toyota 1GRFE Remanufactured Engine undergoes stringent SIM rig testing:

  • Fluid Pressure Validation: The cooling and lubrication systems are fully pressurized to test oil flow across all journals, confirming there are no blockages or internal leaks.
  • High-RPM Spin Testing: The crankshaft is spun dynamically by an electric motor to verify uniform compression across all six cylinders.
  • Valvetrain Integrity: The DOHC timing chain setup is monitored during the spin test to ensure zero slack and perfect valve seat sealing.

Vehicle Compatibility for the Toyota 1GRFE Remanufactured Engine

This 4.0L V6 (3956cc) DOHC long block assembly is a direct drop-in replacement for the following Toyota truck and SUV applications:

Year Range Make Model Engine Details
2005 – 2006 Toyota Tundra V6 4.0L 3956cc
2005 – 2009 Toyota 4Runner V6 4.0L 3956cc
2005 – 2011 Toyota Tacoma V6 4.0L 3956cc
2007 – 2009 Toyota FJ Cruiser V6 4.0L 3956cc

Installation & Initial Break-In Guidelines

To preserve the comprehensive warranty and ensure maximum lifespan for your new Toyota 1GRFE Remanufactured Engine, strict adherence to these installation practices is required:

  1. Radiator & Cooling Flush: Completely flush or replace the radiator assembly. Debris from a previous head gasket failure will destroy the new engine if circulated.
  2. Oil Priming: Fill the crankcase with high-quality conventional break-in oil and manually crank the engine with the ignition disabled to prime the oil galleries.
  3. 500-Mile Break-In Period: Drive at varying speeds and loads for the first 500 miles. Avoid towing, extended idling, or constant RPM highway cruising to allow the piston rings to seat against the newly cross-hatched cylinder walls.
