700R4 cooler lines

[kustomkyle]

Quick question here, the cooler lines going into a GM 700R4/4L60 are what size/type?

From what I can tell, they appear to be standard 5/16" inverted flare lines (brake line), at least on the radiator side. I'm more unsure of the transmission side, hoping it's the same for both the inlet and outlet.

I know they sell them at inline tube and opgi I wanna say they have the measurements on there I think

5/16" line with the same flare on both ends.

Ok, thank you. I have a line that was rigged up with a short piece of rubber hose for no apparent reason on the radiator side (somewhere along the line before we took ownership of the car). Would prefer to get a pre-bent line to replace it, however from everything I've seen, GM no longer makes it and no one reproduces it. It's actually on a B/D body.

If these are for a B body car, you would have to look at a salvage yard for them is my guess. What year car is it? I'm not sure, but you might find someone that reproduces them for the 94-96 Impala SS cars.

Nope, 1993 Cadillac. The radiator and related parts are one-year one-car only even though the bulk of the mechanical parts are the same for 1987-1994 trucks and B/D bodies (though the last year for the TBI for those was 1993). Much less expensive to maintain than the LT1's or even the Vortec (or "Vortex" as a lot if people incorrectly call them, even Jay Leno!).

I'll be just making my own out of a 5/16" standard thread/inverted flare brake line. If I can get it bent properly without kinking it that is. Looks to be 60" exactly.

I bent both lines on a previous car I had. I didn't have any lines to go off, but it wasn't too bad of a job. Having a line, or both, to go off of makes it much easier to get the bends in the right places. I had to replace a brake line on my truck and since I wanted it to look decent, I pulled the old line out and used it as a template-after I pulled the gas tank out as far as I could. Aside from the union I had to use because I couldn't get one line that was long enough, you'd think it was factory.

Harbor Freight cheap line bender is well worth the $$. Get the one that looks like a 1/2 moon with 2 handles and they work great even in tight spaces.

I have both the 1/4" and the 1/2" one. One of the best $20 I spent

Just found a new tubing bender by Lisle and seems to work a lot better. Tested it on a scrap piece of 5/16" line. It's a setup like the cheaper flaring tools where you put the line in and crank down on it.

Not sure how the plier type are supposed to be of any use.
