2.0L Naturally Aspirated Engine Complete Assembly for 2016-2024 Honda

A quick look at your own vehicle makes sure the right engine shows up:

• Confirm the 6th character of the VIN is a 2 (for Sedan) or a 4 (for Coupe).
• Verify the current engine is a 2.0L naturally aspirated model (not a 1.5L Turbo).
• Locate the engine code stamped on the front of the engine block near the transmission interface.

What the install really takes — plan and budget with confidence:

Special tools this job needs:

• Engine hoist and load leveler
• Subframe support bar / engine support fixture
• 14mm 12-point thin-wall spark plug socket
• 50mm Hex Crankshaft Pulley Holder Tool
• Torque wrench and angle gauge

Budget for these consumables at install:

• Engine Oil: 4.4 to 5.6 quarts of 0W-20 full synthetic motor oil
• New OE-spec oil filter
• Honda Long Life Antifreeze/Coolant Type 2
• New intake manifold gasket, exhaust manifold gasket, and throttle body gasket
• New valve cover gasket
• New OEM-spec iridium spark plugs (NGK DILKAR7H11GS or equivalent)
• Crankshaft Pulley Bolt (Honda Part Number 90017-RWC-A01) - Torque-to-yield, strictly one-time use

What your vehicle’s computers will need after the swap:

What’s involved: Crankshaft Position (CKP) Sensor Relearn, Throttle Body Idle Relearn, and Immobilizer Re-marriage

sources differ: Arm 1 states ECU re-marriage is not required if reusing the original ECU, but Arm 2 states an immobilizer re-marriage is typically required. Both agree that a Crankshaft Position (CKP) sensor relearn is required using a Honda Diagnostic System (HDS) or equivalent high-end scan tool to prevent misfire codes.

Pro tips for a smooth first start-up — hand them to whoever does the install:

• Crankshaft Pulley Bolt Torque Sequence: Must follow the exact two-step factory procedure (torque to 37 ft-lbs, then turn an additional 90 degrees). Never use an impact gun.
• Fragile Plastic Components: Composite plastic intake manifold and valve cover are highly susceptible to cracking if bumped or over-torqued.
• Exhaust Studs on Cylinder Head: Be extremely careful not to over-torque the nuts on the cylinder head studs to avoid stripping threads in the aluminum head.
• Subframe Alignment: Mark the subframe alignment before removal to avoid steering wheel off-center issues.
• Immobilizer Relearn: The car will not start until the immobilizer system is reprogrammed.
• Ground Straps: Pay close attention to the location and condition of all engine and transmission ground straps.
• CVT Fluid Level: Be mindful of potential fluid loss from the torque converter and top off with Honda HCF-2 fluid.

Easy to get right once you know them:

• Reusing the Crank Pulley Bolt: Reusing this stretch bolt can cause it to back out, destroying the crankshaft snout and keyway.
• Stripping Spark Plug Threads: Cross-threading plugs in the aluminum cylinder head by not hand-threading them first.
• Using the Wrong Spark Plug Socket: Attempting to use a standard 5/8" socket instead of a thin-wall 14mm 12-point socket.
• Skipping the CKP Relearn: Skipping this step leads to a persistent flashing Check Engine Light or misfire codes.
• Mixing Up 1.5L Turbo and 2.0L NA Accessories: Assuming accessories like the alternator, starter, or A/C compressor are interchangeable.
• Ignoring the VIN Code: Ordering this engine for a 1.5L Turbo model.
• Not Planning for Reprogramming: Failing to arrange for the immobilizer relearn after physical installation.
