how do i remove transmission line from radiator to replace radiator? on 2004 Chevrolet Monte Carlo

19mm wrench or line removal tool to remove tranny line?

Asked by for the 2004 Chevrolet Monte Carlo
i recently replaced my radiator in my 02' chevy xtreme. i got a tranny line removal tool from autozone. if you have problems you can remove the fitting, but replace gasket. the tool takes a little work so be goes over the line and fits at the connection and rotate it too release the retaining spring/clip. you should be able to pull line out. put a pan under as some fluid will come out.
Nick thank u so much for your quick answer. I never used one b4 so i will purchase a 8 pc set, line removal tool online from for $17.66. I was wondering, because I had tried the 19mm flare wrench and the coupling would not even budge!
no problem. good luck and let me know how it went.

Nick, I used the line tool that came with the new radiator and it was a breeze, except the line was stubborn to remove after removing the clip so I used a vise grip locked close to the nut and pried out with a flat head screwdriver in a snap. After everything was put back including new water pump, the car was still overheating with whit smoke coming from tailpipe! Yep looks like a cracked head or block! back to work looking for engine now!
white smoke no good.crate motor time.can always have heads magna flux to check for cracks.
