Since I decided to put a Turbo 350 transmission in place of the original powerglide, the cooling lines to the radiator don't match up. I probably could've purchased some prefab lines, but I've had good luck bending my brake lines so I decided to make my own transmission cooling lines. Keeping in line with the whole do -it-yourself theme. What could go wrong?
Plenty!

| Radiator mounted, but no fan blade |
My lovely wife is out of town this week, so I have the evenings all to myself. With the God-awful temperatures we've been having, I can't do anything in the afternoons anyway, so I thought it would be nice to spend the evenings in the shop happily making my cooling lines, listening to the radio and quaffing a beer or two.
First, I had to purchase my parts. I stopped in at my local NAPA store and ordered a 25' roll of 5/16" tubing and associated fittings. It was going to take a couple of days for the parts to come in, so in the meantime I busied myself with getting the radiator support and radiator mounted. For some reason, I couldn't slide the radiator down between the support and the fan blade. I thought I might have it in backwards, but no, that wasn't possible. I knew the radiator had come out of the car decades ago, so why wouldn't it go back in?
I took the support off and laid it on the floor, thinking I could put the whole thing together and mount it in place. To my surprise, when I set the assembly up on the frame, the fan blade prevented the support from aligning with the mounting holes. Finally, a light bulb went off and I realized that the fan spacer on the water pump was too long. This is not the original engine! I took the fan blade off and victory! Now I have to find a shorter fan spacer.

| The correct tubing, finally! |
Feeling rejuvenated, I picked up my tubing Thursday afternoon, bought a pizza, and headed for the shop. It didn't take long to realize that the tubing, which was nicely packaged in a wrapper with the 5/16" measurement printed on it, was in fact 3/8" tubing. Another roadblock!
So, Friday morning I went back to NAPA and swapped the tubing out for the correct size. Flush with more confidence, I returned to the scene of the crime Friday night to get the job done! The new tubing was clamped into the flaring block for the first fitting. All good. I took my handy little el cheapo tubing bender, made more for 3/16" brake lines than this bigger stuff, and made my first bend. Snap! The bender broke! Shot down again!
I went home and did some reading on what other benders were available out there. It seems that the most popular is one that requires two hands to operate, with one half of the tool wrapping the tubing around the bending block. The other option was a pliers-type which got some positive comments, and looked more manageable, especially with one hand. O'Reilly had one on their shelf, so I committed to picking it up Saturday afternoon.

| Bender one--broken |
Picked up the new tool this afternoon and headed back to the shop. My confidence was beginning to wane, but hope springs eternal. I unwrapped the pliers and, wisely tried them out on the other end of the roll. These pliers have a roller that supposedly works for either 5/16" or 3/8" tubing. It does not!
Maybe I was using it wrong, but the wider groove allows the narrower tubing to kink, and the outer rollers of the tool actually dented the outer side of the tubing. A total bomb!
Back to the store, this time Autozone. They had only one tool on their rack. The unwieldy two-handed tool. It was actually cheaper than the pliers, as well as being my last option.
I returned to the shop felling really deflated. It didn't help that it was still 95 degrees outside and the 6PM sun was blazing in the shop. Undaunted, and determined to get this project at least started, I made my first bend. The tool was a little difficult to manage, by made beautiful bends.
Totally focused now, I bent and fitted, fitted and bent, until I had a reasonably nice line from one fitting on the radiator, to one fitting on the tranny. It took about an hour.

| Bender two--total junk! |
I thought it would work best to pull it out and use it as a template for the other line, which runs the
same route for 80% of the way. Unfortunately, it wasn't as easy as I hoped, but still, after another hour, I had a somewhat decent second line. On the home stretch!
With the second line in place, all I had left to do was put one final bend at the end where it meets the transmission. It worked well bending in in place on the first line, so I went at it again. One more snafu!
I wasn't paying attention, and laid the tubing in the 3/8" groove instead of the 5/16" groove. I
realized it a second too late, which means I put a kink in the line. It's a small kink, and no one but me will ever know, so I left it. Odyssey over!
