Seems like I need a new radiator and mine had the extra large type as it was a work truck. Anyone know for my size truck what equivalent to oem I am looking at? It has a tranny cooler attached. Did. Search See too many variants.

 

Just call a napa or equivalent. Measure your leaky one, take off the cap and see how many rows you see. Prob a 3 or 4 row. Thats it.
