Review on LainKeen Clutch Compatible Removal Engines by Nick Nunez

I used this tool kit to easily replace the cooling fan on my 4.3L GMC Sonoma. The large end of the key fits perfectly into the fan clutch. Another tool, I removed one of the pulley bolts and put it in the tool hole and was then able to use it to keep the pulley from spinning while I loosened the large fan clutch nut.
