I'm replacing all of my lines in my 02 GT. I have new AC Delco transmission cooling lines and also want to replace the fittings that they snap in to on both the radiator and the transmission. I am having a very hard time getting the correct fittings for the radiator.
I have tried:
- Dorman p/n 800721 - too large
- AC Delco p/n 15226661 - to small
I have measured the outer diameter of the threaded portion of my fittings and they appear to 5/8. I don't know if the threads are metric or SAE. The inner diameter is 3/8.
Does anyone know the correct radiator side fittings for the transmission lines?
Thanks
