Just need some simple questions answered. Thanks!


This picture, the sensor circled in red, what is it?


These two sensors go on the side of my heads, I think....
If you could confrim that is where they go and what they are. I think they are the coolent temp sensor and fan switch but not sure and not sure which one goes on which head.


I found this hidden in the back of my engine bay, the previous owner blocked it off for some reason, if you know what it is and where it goes that would be helpful. It appears to be some sort of hose line, it goes into the line that goes off the side of the picture.

Thanks for all the help!

 

First pic is a coolant temp sensor. Second pic is a vacuum line for the accessories like the air vents inside the car. It t's off to the plenum and the ball under the left fender.

 

Ok great thanks, no idea about those two sensors in the second pic?
