Hey guys, I’m replacing the coolant metal pipe on my 2003 ranger 2.3 that goes from upper radiator hose to the back of the engine. I’m having a hard time inserting the pipe with the 2 o-rings to the back connector. The o-rings keep getting stuck out of the pipe and there’s no much room to twist the pipe or pry the ring inside. Is there any trick on how to insert it properly?

if I’m not properly explaining the issue let me know and I’ll post a picture

thsnks!
