How This Part Works

As part of the engine timing system, this tensioner helps keep the timing chain properly loaded so the chain can track the sprockets with the correct relationship. That matters for engines in Hyundai Sonata and Kia Optima applications, where stable timing drive operation supports smooth engine performance and dependable operation.

Common Problems It Can Address

• Timing chain slack in the upper timing drive
• Noise from a worn or weak chain tensioner
• Irregular valve timing caused by poor chain control
• Timing drive wear from inconsistent chain loading
• Service replacement for a failed original tensioner

Installation Notes

Verify engine code and exact vehicle application before installation. Inspect the timing chain, guides, and related components during service, and confirm the upper position matches the original part location. For Hyundai Sonata, Tucson, and Kia Forte or Optima timing repairs, compare the old unit to INA ZT-91080 and the referenced 551 0116 100 number before assembly.
