Installation Notes and Tips

Verify that your vehicle uses the without housing configuration before ordering. Confirm the cooler dimensions and OE reference numbers 157100S010 and 1571038021 against the original unit, and inspect mating surfaces, seals, and oil passages during installation. Because fitment is listed for multiple Toyota and Lexus models, matching the exact application by year and configuration is important before service begins.
