Hello all. I was doing some maintenance under the hood yesterday and noticed a couple of things that I thought were odd and I just wanted to make sure that my fears about them were unwarranted.
These pictures show things that look like they should have stuff connected to them. Correct me if I'm wrong.
The first thing is a little aluminum tube that comes off of the firewall in front of the passenger seat. The only thing I can figure that it's for is to be a drain for the heater core... maybe. If not then am I missing a vacuum tube?
The second thing is a couple of bolt holes in the middle of the block right behind the power steering pump mount. And there are similar holes on the driver side.
My truck is the 3.4L V6 and has had 2 previous owners. I have no Idea what they may have done to it.
