tranny cooler with stock cooler
is there any fittings i need to get along with my b&m 24,000 lb gvw cooler that i need to get in order to run the stock cooler and the b&m together? im gonna run both but dont know how to plumb both in together.
The stock lines are 5/16. The lines with the cooler are 3/8. If you can find a 5/16 x 3/8 brass barbed fitting you're good to go. I couldn't so I got the following:
2) 1/4" fip brass couplings
2) 1/4" mip x 5/16" barbed adapters
2) 1/4" mip x 3/8" barbed adapters
Screw the 5/16" and 3/8" adapters into the couplings essentially making 2 5/16 x 3/8 barbed adapters. Use the 5/16" side to tie into the factory lines. The 3/8 side will tie into the line that came with the cooler. I have the same cooler in my car and this worked well for me.
