Know This Engine Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this engine family:
A quick look at your own vehicle makes sure the right engine shows up:
- Verify your VIN's 4th Digit is 'A'.
- Check your Under-Hood Emissions Label (California SULEV vs. Federal ULEV).
- Confirm your Transmission Type (CVT vs. 6-speed manual) to prepare for flywheel/flexplate transfer.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine hoist/crane with a load leveler
- 14mm thin-wall 12-point spark plug socket
- Precision torque wrench
- OEM-compatible diagnostic scan tool
Budget for these consumables at install:
- Engine Oil (0W-20 Full Synthetic or 5W-30 depending on spec; approx 4.2 - 4.5 liters) & Filter
- Engine Coolant (Nissan Blue Long Life 50/50 Pre-Diluted)
- Spark Plugs (NGK DILKAR6A-11 for California emissions, or PLZKAR6A-11 for Federal)
- Intake manifold gasket set
- Exhaust manifold gasket
- Thermostat and water outlet gaskets
- Accessory Drive Belt (Serpentine belt)
- PCV Valve (Brand-new OEM black PCV valve)
What your vehicle’s computers will need after the swap:
What’s involved: Idle Air Volume Learning (IAVL) / Throttle Relearn & Crankshaft Position (CKP) Sensor Relearn
sources differ: Arm 1 states a dealer scan tool (or high-end professional bi-directional scan tool) is required for Idle Air Volume Learning. Arm 2 states that while some advanced aftermarket scan tools can perform these relearns, a Nissan-specific scan tool (like the dealer's CONSULT tool) is the most reliable method. Cautious choice: 'yes' or 'model_dependent' for dealer tool, but set to false as high-end aftermarket tools can perform it, though dealer tool is highly recommended.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- The Spark Plug Torque Trap: Cylinder head is fragile around spark plug threads. Never tighten on a warm/hot engine. Torque strictly to 14 ft-lbs (19.6 Nm).
- Flywheel / Torque Converter Bolt Access: Access torque converter nuts through the starter motor mounting pocket. Ensure crankshaft rotates smoothly by hand before starting.
- Electronic Throttle Body Care: Do not manually push or force the brass throttle plate open with your fingers to clean it.
- Engine Mount Design: The primary passenger-side engine mount bolts directly to the timing chain cover, making the cover a structural part of the engine.
- Accessory Removal: Removing the front bumper cover and radiator provides much better access for removing the engine from the top.
- Alternator Bolt: The alternator has a bolt that is difficult to remove without sliding the alternator in a specific track designed into its mounting bracket.
Easy to get right once you know them:
- Cracking the Cylinder Head During Spark Plug Installation by over-torquing or tightening on a hot engine.
- Reusing the Donor Engine's Sensors and PCV Valve, which triggers immediate check engine lights due to emissions package differences.
- Skipping the Idle Relearn Procedure, leading to extremely high or surging idle.
- Using Aftermarket Sensors instead of genuine OEM camshaft and crankshaft position sensors.
- Not Swapping Key Parts like the original intake manifold, fuel injectors, and engine harness.
- Failing to Clean Components like the throttle body and intake passages before installation.
Not issues with the units on this page — the manufacturer documented these for every engine of this family, wherever you buy one. Handy for your installer:
🔎 Recommended at install: Replace the PCV valve with an updated black-colored valve and reprogram the Engine Control Module (ECM).
🔎 Recommended at install: Reflash the ECM with updated software.
🔎 Recommended at install: Inspect/replace the PCV valve and clean the throttle chamber.
🔎 Recommended at install: Diagnose JATCO CVT slippage; often misdiagnosed as engine hesitation or misfire.
🔎 Recommended at install: Never tighten spark plugs on a warm or hot engine, and always use a torque wrench to tighten strictly to 14 ft-lbs (19.6 Nm).
🔎 Recommended at install: Replace stuck oil control rings or clogged PCV valve.
🔎 Recommended at install: Replace timing chain, tensioners, and guides.
🔎 Recommended at install: Replace the vent control valve O-ring.

Policies, in plain English.
Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance
120-Day Warranty
This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included
- Warranty covers defects — not installation errors, misuse, or damage after installation
Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion

- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
