2000 explorer pwr steering cooler removal

Is the cooler actually needed? I only drive about 60 miles/month due to a disability of chronic back. I bought a cooler used from ebay from a 2000 expedition, and don't know if it fits yet. My brother is the 'mechanic' of the family, and if the cooler can just be by-passed, I can tell him it's ok to do so.

Welcome to this forum! The cooler keeps the fluid at a low temperature. Heat destroys the seals & hoses, and shortens the life of the fluid.
