About this product

The Union (#90404-16021) is a critical Drive-Chassis part in the Oil Cooler & Tube (Atm) system of Toyota vehicles. Its primary role is to facilitate the smooth and efficient flow of engine oil within the system.

Over time, however, it's possible for the Union (#90404-16021) to become clogged or damaged. In these cases, vehicle performance may decrease and engine overheating could occur. It is therefore essential to periodically replace this part with a genuine Toyota Union (#90404-16021) to maintain vehicle compatibility. Purchasing a genuine Toyota part guarantees not only perfect fit and function but also the backing of Toyota's genuine parts warranty. The Union (#90404-16021)'s contribution to the Oil Cooler & Tube (Atm) system is indisputable, with its effective function leading to engine longevity and, ultimately, safer vehicle operation.
