solution in one example the glycol based solution is a water and glycol solution within cooling system the water solution may include any of a variety of a family of hydroxy ethers as such when impeller 70 is rotating it pumps or circulates the water glycol solution throughout the cooling system while wrap spring device 40 is engaged and then stops circulating the water glycol solution when wrap spring device 40 is disengaged housing 48 holds the components in the proper position and provides a container for the water glycol mixture in one case housing 48 includes first and second halves 48 a and 48 b which are bolted together with bolts or fasteners to form housing 48 the water glycol mixture is able to freely flow around the components of wrap spring device 40 including spring 64 control plate bushing 49 and control plate 50 bearing 44 supports shaft 42 and seal 46 prevents water from leaking out of housing 48 retaining ring 72 holds impeller 70 and hub 68 in the proper axial position with respect to collar 62 in one embodiment the glycol based or water based solution surrounds all the components of wrap spring device 40 and is circulated throughout the system in one example the system is the cooling system of an automobile in one embodiment the water based solution is a type of hydroxy ether such as water glycol mixture for example ethylene glycol or propylene glycol can be mixed in.
