This timing chain tension‑side guide 13085‑EA200 is a key consumable timing‑system component for Nissan VQ40DE 4.0L V6 gasoline engine. Installed on tension side of timing chain, it limits lateral swing of timing chain, absorbs vibration impact and lowers friction loss during engine running, keeps timing chain running in correct track. It is aftermarket replacement for Nissan Xterra, Frontier, Pathfinder and NV series full‑size vans from 2005‑2021.
Adopts steel‑back reinforced nylon composite material. Metal skeleton guarantees mounting rigidity; high‑wear‑resistant nylon sliding surface bears long‑term friction contact with timing chain, with excellent high‑temperature resistance and oil‑corrosion resistance. Precision‑drilled mounting holes fully match original installation position.
Common failure symptoms: timing chain rattling noise from engine front cover, heavy surface abrasion, guide rail cracking, increases risk of timing‑chain jump. Normally replaced together with timing chain, tensioner and other timing components during engine overhaul. Every guide rail passes dimension inspection before shipment, no modification required for installation. Important single spare‑part for VQ40DE engine timing maintenance.
