01 / Confirm the configuration
Match your Isuzu 4JG2 Engine before ordering.
The 4JG2 has a displacement of 3,059cc and four cylinders. Engine code alone does not confirm that every installation component will match. Have your mechanic compare your existing engine with the proposed long motor before purchase.
| Engine code | 4JG2 |
|---|---|
| Capacity | 3.1L / 3,059cc diesel |
| Configuration | Four-cylinder |
| Condition | Brand new |
| Supply | Long motor — not a complete motor |
| Availability | Available on backorder; confirm lead time |
Send your VIN or chassis details, build date, engine-code photograph and clear pictures of the original assembly. Turbocharged and naturally aspirated applications must be assessed separately. Sump, mounts, fuel system, manifolds, sensors and flywheel arrangements may differ.
Do not assume this Isuzu 3.1 diesel engine interchanges with a 4JB1, 4JX1, 4JJ1 or another Isuzu engine simply because the vehicle or engine looks similar.
02 / Your engine supply
Brand new 4JG2 long motor.

$8,905 $6,850 incl. GST
SKU: CEA-4JG2-LM
Plan the component transfer.
Do not expect a complete engine with all accessories. Your workshop will need to identify the compatible fuel-system components, intake and exhaust equipment, turbocharger where fitted, electrical accessories and vehicle-specific fittings to transfer.
Confirm the final written inclusion list before ordering. Inspect reused components and replace damaged or unsuitable parts before fitting.
03 / Installation planning
Prepare your Isuzu 3.1 diesel engine replacement.
Diagnose why the original engine failed before installing the replacement. Check the cooling system, lubrication system and fuel supply. Contamination or a faulty external component can damage a replacement engine if the original cause is not resolved.
Before fitting
Have a qualified mechanic confirm the engine specification, transfer requirements and installation procedure. Obtain a separate quote for labour, fluids, filters and any ancillary repairs.
Commissioning and records
Follow the correct workshop procedure and supplied instructions for priming, first start, run-in and servicing. Keep invoices and service records. Do not book a fixed installation date until the backorder lead time is confirmed.
For technical background, consult the Isuzu workshop manual; your mechanic must use the procedure applicable to your exact engine configuration.
