2022+ Redesigned Engine Oil Cooler

I noticed 2022+ 4runner have a different oil cooler design. P/N 1571031101.

Anyone know the reasoning behind the change ? Don’t recall any issues from the previous design.

 

if you interested, why don't you research it more and post your findings here ?

 

Welcome.
Have you confirmed that it is a complete redesign?

 

welcome

 

2022-2024 4Runner: P/N 1571031100

Looks identical to the unit used in the 200 Series land cruiser and 2nd Gen Tundra, shown below.



2010-2021 4Runner: P/N15710-31040


The timing of the change is exactly during the Covid/supply chain era so it feels like they had to change suppliers or use existing parts.
The oil filter housing also changed for 2022+.

Physically, the inlet/outlet ports on the unit are in different locations and the old unit seems to have a “housing” or shield around it.

anyways, I figured it was an interesting find to share, given how old the 5th gen is and mostly unchanged over the years.
I know I can’t be the only one that nerds out about heat exchanger designs

 

Thank you!
