Nissan VG30 3.0L V6 Remanufactured Engine – 7/83-4/87

Nissan VG30 3.0L V6 Remanufactured Engine – Professional Overview

The Nissan VG30 3.0L V6 Remanufactured Engine provides a replacement solution for compatible Nissan applications produced from July 1983 through April 1987. This engine belongs to the Nissan VG30 V6 family and is identified by Block Cast #V52 and VIN Code H.

For replacement-engine buyers, accurate identification is essential. Vehicle fitment should be confirmed using the applicable vehicle information, model-year details, and casting numbers before ordering. This helps ensure that the replacement engine corresponds with the original powertrain configuration.

The engine is remanufactured rather than simply inspected and resold. Its process involves disassembly, cleaning, component inspection, machining, replacement of specified internal components, reassembly, and final SIM testing.

Compatibility, Applications, and Engine Identification

This Nissan 3.0L V6 replacement engine is listed for applications covering the 7/83-4/87 production period. The supplied identification information specifies a VG30 V6, Block Cast #V52, and VIN Code H.

Because engine configurations can vary between vehicles and production periods, buyers should verify compatibility before purchasing. Casting numbers and vehicle-specific fitment information provide important reference points when matching a replacement engine.

The VG30 platform is a 3.0-liter V6 engine configuration, making this replacement relevant to Nissan vehicles that originally used the specified VG30 application.

For additional replacement options, buyers can also explore related remanufactured Nissan engines, V6 replacement engines, and other engine assemblies within the engine category.

Remanufacturing Process and Quality Control

The engine undergoes a comprehensive remanufacturing process intended to restore the assembly to a serviceable condition.

The process begins with complete engine disassembly. Components are separated so that individual parts can be cleaned and evaluated rather than simply inspecting the engine externally.

Cast-iron components are hot tanked, while aluminum components are thermally cleaned. This deep-cleaning stage prepares the components for inspection and machining.

During inspection, Magnaflux testing uses magnetic particles to identify microscopic cracks and fissures that could affect long-term engine reliability. Components are also visually inspected.

The deck surfaces are CNC machined, and new components are incorporated during assembly. Listed replacement components include bearings, pistons, rings, lifters, oil pump, gaskets, Viton valve seals, freeze plugs, and galley plugs.

Depending on the engine configuration, the timing system receives either a new timing chain with new tensioners or a new timing belt with a new tensioner. Where applicable, an engine using a timing-driven water pump also receives a new water pump.

Engine Assembly and Performance Verification

Following machining and component replacement, the engine is carefully reassembled according to the remanufacturing process.

A critical part of the quality-control procedure is SIM testing. After assembly, the engine’s cooling and oil systems are fully pressurized while the crankshaft is spun at high RPM.

This testing procedure provides an additional verification stage for compression, lubrication-system integrity, cooling-system pressurization, and overall build quality before the engine is supplied as a replacement unit.

For buyers replacing an aging original engine, this testing provides an important distinction between a professionally remanufactured assembly and an untested used engine.

Why Choose a Remanufactured VG30 Replacement Engine?

Replacing an older engine requires more than matching displacement alone. The engine must correspond with the appropriate application, identification information, and configuration.

This VG30 3.0L V6 replacement engine offers a remanufactured alternative with a documented process covering cleaning, inspection, machining, component replacement, assembly, and testing.

The supplied engine identification information also makes it easier for buyers and technicians to cross-reference the engine against existing vehicle and casting information.

For restoration projects, replacement applications, and vehicles requiring an original-type powertrain configuration, accurate engine identification remains an important part of the purchasing process.

Who This Engine Is Best For

This Nissan VG30 remanufactured engine is intended for buyers who need a replacement engine for a compatible Nissan application within the specified 7/83-4/87 production range.

It can be relevant to:

• Vehicle owners replacing a worn or failed original engine
• Automotive repair professionals sourcing a replacement powerplant
• Restoration projects involving compatible Nissan applications
• Buyers looking for a professionally remanufactured V6 engine
• Workshops requiring an engine identified by VG30, Block Cast #V52, and VIN Code H

Fitment should always be verified against the vehicle before purchase.

Technical Specifications

Ordering, Fitment Verification, and Support

Selecting the correct replacement engine starts with accurate vehicle identification. Buyers should compare the vehicle’s model year, engine configuration, VIN information, and available casting numbers with the applicable fitment information before ordering.

The V52 block casting number and VIN Code H provide additional identification information for this engine. These details can be particularly useful when working with older Nissan applications where multiple engine configurations may exist.

Professional assistance with engine identification and compatibility can help reduce the risk of ordering an incorrect replacement. Buyers should provide the relevant vehicle and engine information when requesting fitment assistance.
