I dunno about an explorer, buy my 95 Jeep Wrangler's oil pan was a royal PITA! about 20 bolts, all of various lengths and I believe two different sized heads, and man...holding that pan up with one hand while trying to get enough bolts started to hold it up AND keep the gasket in place.....
Never Again!
Shortly after that, I tackled the auto trans' oil pan...even worse! Some tasks were just meant for a pro mechanic to do, I think.
Hopefully an Explorer is easier....
