Description

Datsun 240Z S30 (70-73) Mishimoto aluminium radiator

The Mishimoto radiator 240Z is a full aluminium performance radiator for the classic Datsun 240Z built from 1970 to 1973. It replaces an old, clogged or leaking original radiator one-for-one and keeps the L-series engine at a stable temperature in traffic or on a hot track day.

An L24 or L26 that is driven hard, or a tuned engine, needs more cooling capacity than a radiator that is more than fifty years old can deliver. This radiator has a brazed two-row aluminium core that is 42 mm thick, TIG-welded aluminium end tanks and 35 mm connections. That makes it a logical upgrade for a 240Z that sees track days, drift events or simply a lot of road miles.
