Large size Wrenches for ac and Quick couplers

[jmcleek]

Becca here, jmcleek's kid. Maybe you know the some of the answers to my questions. I would like to know what sizes wrenches to get for ac units in vehicles of all types. I'm going to Ivy Tech to get my degree in Automotive Technology and am learning on all sorts of vehicles. I would also like to know what size wrenches to use for fan clutches and all the other sizes for the big nuts on the vehicles because I hear from my Dad that they are a little more universal than the stamped ones that are regularly used for fan cluches. One more thing, what kind of quick-couple tools can I get for the ac and heater units and other systems on vehicles that are more complete?
