Oil Drain Plug Confusion-35A

Bud W · Apr 10, 2013

There are two plugs in front of the oil filter and one plug close too but behind the filter. Do you drain the crankcase by opening all three plugs? I have an owners manual but its vague at best. Thanks

Not positive, but it is likely the front ones are for water/coolant. HTH

Oil came out of both front ones. I have determined that the plug behind the filter is to drain the transmission. I would like to know why there are two drains plus the oil filter drain for the crankcase?

No idea.

The plug just ahead of the oil filter is in the bottom of a sump with a raised ridge around it on the inside. It's the sump for the oil pump pickup. The other plug is just outside of this sump and will drain a little more oil that is trapped outside the sump.
The other drain is for the tranny. There's more than one of those too : )
