Question:
I’m installing the Derale 13504 on my 2018 Chevrolet LT 4.3L. Does it matter which trans hose connect to the inlets on the cooler or do they have a specific order? Thanks

No, it does not matter Brian. The Derale Series 8000 Plate & Fin Cooler item # D13504 uses a non-directional design. You can connect the transmission hoses to either of the two inlets, and fluid can flow in either direction without any impact it's performance.
The Derale Series 8000 Plate & Fin Cooler item # D13504 is exactly what you need for a 2018 Chevy Silverado 1500. It's going to work with the V6 4.3L engine and the 5.3L or 6.2L V8 engine models. The cooler itself measures 11" wide x 12" tall x 7/8" deep and comes with the necessary clamps, connectors, and tubing.
What do you tow with your Silverado?
