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 8th digit is 7
- Confirm your drivetrain (FWD vs AWD) to determine if oil pan swap is required
- Locate the engine code stamping on the block to confirm PE family designation
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Fuel Pump Lock Ring Tool (SST 49 F042 001)
- 27mm Deep-Well Socket
- Engine Hoist and Load Leveler
- Water Pump Stretch Belt Tool
Budget for these consumables at install:
- Engine Oil (0W-20 full synthetic, approx 4.4 US quarts / 4.2 liters)
- Oil Filter
- Engine Coolant (Mazda FL-22 spec long-life coolant)
- Spark Plugs (Mazda Genuine Iridium PE5R-18-110 or PE5S-18-110)
- Valve cover gasket
- Intake manifold gaskets
- Exhaust manifold gasket
- Main accessory drive belt
- Water pump stretch belt
What your vehicle’s computers will need after the swap:
What’s involved: Crankshaft Position (CKP) Sensor Relearn, Throttle Body Idle Relearn, and Immobilizer (PATS) Security Relearn
sources differ: Arm 1 states no programming is required for the physical engine itself if original ECU is kept, though relearns are needed. Arm 2 states programming is model-dependent and recommends an immobilizer security relearn to ensure proper communication. Cautious value 'model_dependent' selected.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Water Pump Stretch Belt: Driven by a small, dedicated stretch belt that does not use a mechanical tensioner. Requires a specialized stretch belt tool.
- AWD vs. FWD Oil Pan & PTU Mounting: If swapping between AWD and FWD platforms, you must swap the oil pan and the intermediate shaft/PTU mounting brackets.
- Torque-to-Yield Crankshaft Bolt: The crankshaft pulley bolt is a torque-to-yield fastener and must be replaced with a brand-new one if loosened.
- Fragile High-Pressure Fuel Lines: Highly sensitive to twisting. Always use a backup wrench on the fuel rail fittings.
- Sensor Fragility: Numerous critical sensors (ion sensors in ignition coils, MAF, etc.) must be handled with extreme care.
Easy to get right once you know them:
- Reusing the Crankshaft Pulley Bolt
- Failing to Swap the Oil Pan on AWD Models
- Using Cheap Spark Plugs
- Mixing Coolant Types (using universal green instead of Mazda FL-22)
- Ignoring the ECU/Immobilizer Security Relearn
- Damaging the Wiring Harness during transfer

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.
