'96 Trooper Drain Plug Size

External Since: Nov 23, 2007 Posts: 4

I've been changing the oil in my '96 Trooper lately and will continue
to do it myself. I've been using a big crescent wrench to loosen the
drain plug. I'd like to get the correct size socket or wrench, what's
size do I need to get? My measuring the crescent wrench isn't accurate
enough.

Thx - Steve
