Oil Cooler Line Fitting size

[df2x4]

I actually have about 15' of braided Russell lines left over from my 80E swap... I might just have to use it for replacing my oil cooler lines in the Suburban. Pretty sure they're leaking as we speak...

Found a 20mm x 1.5 to -6AN adapter from Vibrant Performance for anyone looking. Part number 16620.

What size line did you use?

I used -6AN Russell ProFlex for the transmission lines. This stuff, I bought a 50ft roll.

Should work fine for the engine oil cooler lines as well.

I used this stuff on my truck. I called Parker and made sure it was rated for Gasoline and ATF/Hydraulic Fluid. I ran 1/2" for fuel, 3/8" for return, And 3/8" for trans cooler lines.

The outlet on my new Oil Cooler Adapter for my LS is a -10 AN. I was assuming that running a -10 line size was correct. Am I running a bigger size than I should?

I don't think it matters much. Couldn't you just get new -6AN adapters to screw into your cooler though? What cooler are you running?

The cooler is the stock one in the truck. The adapter has 10 AN fittings on the inlet and outlet.

You mean the lines coming from the engine? Huh. I figured those would just be 3/8" NPT like the factory GMT400 ones.

So 3/8" is the factory size.
