2004 Nissan Pathfinder 4 WD 3.5 L / auto. Engine Oil pan has a unique shape to c

lear front axle...the lowest point of the pan appears to be just behind the right front axle. It has what appears to be a drain plug, but it has a small weld securing it...easily broken I'm sure. Is that it? Wondering if dealers change oil by sucking it out the dipstick or am I missing the actual plug somewhere else. the filter is in front and I cut a small but efficient opening in the plastic pan so I can get the filter out without removing the 8 bolts holding the dust cover in place each time. Oil change about to begin so thanks for a rapid reply
