2020 Honda Odyssey · 3.5L V6 · EX factory procedure checked
The 2020 Odyssey service manual includes timing-belt, crankshaft-pulley, and water-pump removal and installation instructions for the EX selection, with tool requirements, timing diagrams, torque values, inspection, and replacement-marked hardware. The 2020 owner guide places timing-belt replacement under Maintenance Minder sub-item 4 and calls for water-pump inspection.
This job involves supporting the engine, removing a side engine mount and crankshaft pulley, and controlling the timing-belt adjuster. Use the required pulley holder and proper engine support, observe every replace-marked fastener, and follow Honda's diagrams and torque sequence. Stop if the engine is not safely supported or the correct tools are unavailable.
For the 2020 Odyssey, Honda lists timing-belt replacement and water-pump inspection in Maintenance Minder sub-item 4, alongside spark-plug replacement and valve-clearance inspection. The normal schedule follows the vehicle's Maintenance Minder; Honda specifies 60,000 miles (100,000 km) for regular operation above 110°F (43°C) or below −20°F (−29°C).
