Buying a used Honda or Acura with the J35 V6: what to check

A used-car buyer's guide to Honda and Acura V6 models (Accord, Odyssey, Pilot, Ridgeline, Acura TL, MDX, RL): timing belt, VCM, engine mounts, valve adjustment and AC, with real owner-reported prices.

Covers: Honda Accord V6, Odyssey, Pilot, Ridgeline and Acura TL, MDX, RL, RDX (2013+) and others with the J-series V6.

The J35 will run a very long time if you do the one big job on schedule: the timing belt and water pump. That's the line item that makes or breaks a used Odyssey, Pilot or MDX deal. The other common ones are engine mounts, VCM-related oil use and misfires on some years, and AC compressors on older cars.

What to look for

Proof of the timing belt and water pump service if the car is near or past the interval. Ask for the invoice and the date, not just the mileage.
Vibration at idle or a clunk when shifting into drive (engine mounts).
Oil use between changes and fouled plugs on VCM engines.
Ticking from the top of the engine (valve clearance).
Cold AC. Check it even in winter.

Pre-purchase inspection checklist

Ask the shop doing the inspection to cover these, on top of their normal checks.

Confirm the timing belt record or the sticker under the hood.
Check engine mounts with the engine running, in drive and reverse.
Scan for misfire codes and check plugs on VCM engines.
Test the AC for cold air and listen for the compressor clutch.
Ask about valve adjustment history on higher-mileage cars.
