I have a Chevy 4x4 with a 454 engine and I am trying to replace the oil coolant lines. I've replace lines on a 350, but these are different. On the 350, the lines attach directly into the oil filter adapter and have plastic clips that allow removal of the lines by squeezing them together. On the 454, the lines attach in front of the adapter, and they seem to be held on with a retaining clip.
However, I only know this by looking at the new lines. I can't see the retaining clip on the old lines, and it seems that there are large nuts holding the lines on. I read elsewhere that all I need to do is remove the clips, but yet I can't get at the clips, nor even see them.
I've looked in Chilton's manuals, Haynes manuals and scoured the web for this information, yet it is not published and I only found one weak reference on the web to this issue. Do I need to loosen these nuts to expose the clips? If so, are they right or left handed threads?
Any help is greatly appreciated!
