The CoLuck 32mm & 36mm Fan Clutch Wrench Set is built to simplify a job that can otherwise be frustrating: removing temperature-dependent viscous fan clutch lock nuts. This kit pairs two common fan clutch wrench sizes (32mm and 36mm) with a water pump pulley holding tool, helping you keep the pulley from spinning while you work.

Designed with a 15-inch length for added leverage, the wrench and holder aim to make hard-to-reach fan clutch nuts easier to break loose. A rubber-covered middle handle helps with grip and comfort during longer jobs, and the tools feature a powder-coated finish.
Basic use is straightforward: secure the pulley holder bar to the water pump face using the pulley bolts, place the appropriate 32mm or 36mm wrench on the fan clutch nut, and turn clockwise to loosen (per the product instructions). If the bar’s hole sizes don’t match your pulley bolts, the instructions note removing the bolts and reinstalling them over the bar.
Vehicle fit note: The listing notes this set is not compatible with certain vehicles, including Chevy Astro Van and some Ford F-150, Ford F250 7.3 Powerstroke, and Ram 2500 applications. It also lists compatibility with many BMW models/engines (including E-series and various M/S engines). Always confirm your required nut size and application before ordering.
