Well, I finally got to the task of pulling my radiator yesterday. Radiator is out, bracket has been cut, and bolt on mounts will be welded on in days to come.
Radiator has such pretty Statue of Liberty green streaks on it, although I never saw it leak. Fins near the bottom are beat up pretty badly. I plan to have it re-cored and install a lower guard.
I got all the lines loose except one transmission cooler line, which was rusted so badly I just went ahead and twisted it in two to get it removed. Since I now need new cooler lines, is there any advantage to
going with the 3/8" diameter lines? I know the larger line flows more volume, but I didn't know if the factory cooler would be able to increase the amount of heat removed with the larger flow. I think Jim K
may have cooler lines for a 403, or I can make my own. What is everyone's recommendation on going with the larger lines? Or is a waste of time and effort?
Second question. After pulling the radiator, trans fluid was still leaking from the cooler line. I put a pan under it and quit for the evening. Today, I was surprised to see two or three quarts of fluid in
the pan. Did I manage to accidentally partially drain the converter?
