Product Description

The Mishimoto MMRAD-LCR-58X is a direct-fit 3-row performance aluminum radiator engineered for the 1958-1984 Toyota Land Cruiser FJ40 and compatible FJ-series models equipped with the F 3.9L or 2F 4.2L inline-6 engine. The stock FJ40 radiator - by now 40 to 65 years old - is a common failure point prone to corrosion, leaks, and reduced cooling efficiency. Mishimoto's fully aluminum replacement eliminates these weaknesses with a 3-row brazed aluminum core and TIG-welded aircraft-quality aluminum end tanks, delivering a substantial increase in coolant capacity (4.99 gallons) and heat dissipation for stock, modified, and hard-working off-road builds.

The radiator supports both manual and automatic transmissions, featuring an internal transmission cooler with female 1/4-inch BSPP ports for automatic fluid temperature regulation. All factory inlet, outlet, and sensor connection points are retained for a straightforward bolt-on swap. The included magnetic drain plug captures metallic debris during coolant changes, and the high-pressure radiator cap raises the coolant boiling point for added safety in demanding conditions. Backed by the Mishimoto Lifetime Warranty, this radiator is the definitive cooling system upgrade for any FJ40 owner - whether a trail rig, overland build, or restored classic.
