Oil Cooler Line O-Ring, 13.4x1.78, CRP (17222245358)

This o-ring seals the oil cooler hose to the oil cooler and/or the engine or transmission. If your transmission has an oil cooler or the engine has an oil cooler, this is the o-ring to seal the hose at the connection. Often times the hose itself is not the source of the leak (but look closely to be sure) and this o-ring can fix pesky little leaks.
