Belt Tensioner Wrench Set 9pc 12-19mm Timing Serpentine Aux

A 9-piece belt tensioner wrench set for working on auxiliary, serpentine and timing pulley tensioners. It includes interchangeable heads from 12mm to 19mm along with a bar featuring a locking system, giving you a practical way to reach and hold tensioners during belt work.

Used for cambelt replacement, auxiliary belt changes and serpentine belt servicing, this set suits garage work, workshop use and home vehicle maintenance. When access around the front of the engine is tight, the interchangeable head system helps you match the wrench to the tensioner size needed for removal, adjustment or refitting. It is a useful option for mechanics and DIY users carrying out routine servicing or belt-related repair jobs.

The supplied size range covers 12, 13, 14, 15, 16, 17, 18 and 19mm heads, which are common sizes for tensioner applications on many vehicles. The bar includes a locking system to help keep the selected head in place while working, which is useful when space is limited and you need controlled movement around pulleys and belt runs. Having the heads together in one set also helps avoid switching between separate tools when dealing with different tensioner fittings during regular maintenance.
