Im taking the wiring harness off and Im trying to take these two sensors off the back of the block. Thats the oil filter due east. Just wanted to know what the trick was? I really dont want to break them.

Thanks

 

All I see is a red X..

 

yup red x here too.

 

are you referring to the oil and coolant sensors on the back (can't see a pic either)? or maybe the knock sensor?

you will need a large wrench or large, deep socket to remove them from the block safely. i can't remember off the top of my head what size, but they are in the 24-28mm range. though all are different sizes i think. they can be hard to get to with the IM, Alt., hoses and other brackets still on the back of the block. but easy to get them loosened with all that stuff removed first.
