Vehicle Fitments
This JDM J35Y5 long block is designed for the following North American (USDM) models:
-
2016-2020 Acura MDX (Base, Technology, Advance, Entertainment)
-
2019-2020 Acura MDX A-Spec (Direct long block replacement)
Note: This engine is specifically for the 3.5L non-hybrid models.
Installation & Technical Notes
The J35Y5 is a sophisticated, direct-injected engine. To ensure a successful installation and maintain your warranty, please follow these technical guidelines:
-
Long Block Conversion: This sale includes the engine block, cylinder heads, and internal components. You must transfer your original USDM intake manifold, fuel rail, direct injectors, wiring harness, and sensors. This ensures 100% compatibility with your vehicle’s ECU and emissions equipment.
-
VCM Components: While the JDM J35Y5 features the same Variable Cylinder Management architecture, we recommend swapping your original VCM solenoid/spool valve if your USDM unit is known to be in good working order.
-
Direct Injection Care: Ensure your original high-pressure fuel pump is cleaned and inspected before transferring it to the new engine. Any debris in the DI system can lead to immediate injector failure.
-
Essential Maintenance: We strongly recommend replacing the following parts during the swap:
-
Timing Belt Kit: Replace the belt, water pump, and hydraulic tensioner (Interference Engine).
-
Spark Plugs: Use only NGK Laser Iridium (DILZKR7B11G) specifically for the J35Y5.
-
Engine Oil: 0W-20 Full Synthetic oil only.
-
Coolant: Genuine Acura/Honda Type 2 Blue Long Life Coolant.
-
-
Transmission Pairing: Ensure the dowel pins are correctly aligned when mating the engine to the 9-speed ZF automatic transmission. Improper alignment can lead to front pump failure in the transmission.
-
ECU Adaptation: After installation, use a professional-grade scan tool to perform a "CKP (Crank Pattern) Learn" and clear all VCM adaptation values so the computer can sync with the new rotating assembly.
