i was advised to see if any of the bolts were loose on the oil pan, was wondering what size bolts are on the oil pan and what size the plug was

 

the oil pan bolts should be 10mm and the drain plug should be 15mm.

 

On my 2003 4WD, the oil pan bolts are 13mm. I didn't check the oil drain bolt. On the 4WD, some of the bolts are hard to get to.

 

yea i took notice after your replies, theres 4 to 5 bolts that i wont be able to get to, i can see them, but they're completely blocked by other things. thank you for the quick response guys...much appreciated.
