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 the 5th digit of the VIN is 'Z' or '8'.
- Confirm the vehicle is All-Wheel Drive (AWD) by checking for front axle shafts extending from the front wheel hubs into the oil pan area.
- Locate the engine code stamping on the rear passenger side of the block to confirm it reads '2GR'.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Toyota/Lexus Oil Filter Wrench (SST 09228-06501)
- Engine hoist and load leveler
- Toyota Techstream or equivalent professional bi-directional scan tool
Budget for these consumables at install:
- 0W-20 full synthetic oil (6.8 quarts for AWD models)
- OEM Lexus/Toyota oil filter cartridge
- Toyota Super Long Life Coolant (SLLC) (pink, pre-diluted 50/50)
- 6 new OEM Denso FK20HBR8 Iridium spark plugs
- Upper and lower intake manifold gaskets
- Exhaust manifold gaskets
- Thermostat gasket
- Front differential axle shaft seals
- High-quality black RTV sealant (Toyota Black FIPG 08826-00080)
- One-time-use high-pressure fuel pipe joints and O-rings
What your vehicle’s computers will need after the swap:
What’s involved: Crankshaft Position (CKP) Sensor Relearn and Fuel Trim Reset
While the engine will start and run on the original computer, a Crankshaft Position Variation Relearn must be performed if the sensor or flywheel is disturbed. Additionally, learned fuel trims and fuel pump pressure adaptations must be cleared to prevent rough idle or rich/lean codes.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- The front differential bolts directly to the upper oil pan, and the passenger-side axle shaft passes through a sealed tunnel in the oil pan. Align carefully and replace the inner axle seals.
- Proactively reseal the front timing cover while the engine is on the stand to avoid an expensive engine-out repair later.
- The metal high-pressure fuel lines under the intake plenum are one-time-use only and must be replaced to prevent fuel leaks and fire hazards.
Easy to get right once you know them:
- Ordering this AWD-configured engine for a Rear-Wheel Drive (RWD) vehicle, which has a completely different oil pan and subframe clearance.
- Reusing the original water pump and thermostat instead of replacing them easily while the engine is on the stand.
- Using the wrong oil filter cartridge (AWD and RWD versions use different filter caps and cartridges).
- Attempting to use a different ECU instead of transferring the vehicle's original ECU, which triggers the immobilizer system.
- Reusing old gaskets and seals, leading to immediate post-install leaks.
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: Inspect and reseal the front timing cover with fresh RTV silicone sealant while the engine is on the stand before installation.
🔎 Recommended at install: Replace the mechanical vacuum pump with an updated, redesigned unit.
🔎 Recommended at install: Acoustic issue only; no mechanical remedy required unless failure occurs.
🔎 Recommended at install: Reseal or replace seals around the cam sensor bolt holes.
🔎 Recommended at install: Ensure the vehicle's low-pressure fuel pump safety recall has been performed by a dealer (pump is located in the fuel tank, not on the engine assembly).
Researched from factory recalls, TSBs and OEM service data (reference unit 300-84048A-4557661). Unit-specific details — mileage, condition, warranty, freight — are covered in the checkout interview.
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
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- 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.
