Description

Lexus IS300 (01-05) Mishimoto aluminium radiator

The Mishimoto radiator IS300 is an all-aluminium radiator for the 2001-2005 Lexus IS300 3.0 with the 2JZ-GE. It is designed specifically for the IS300 and fits without cutting or modification.

The two-row 36 mm core is fully brazed and the end tanks are TIG-welded. According to Mishimoto this gives 30 percent more cooling than the stock radiator, with greater fluid capacity and better heat dissipation. That applies to a stock 2JZ-GE and just as well to a modified engine or a track project. The included 1.3 bar high-pressure radiator cap raises the boiling point of the coolant.
