What This Radiator Helps Address

• Overheating caused by reduced radiator efficiency
• Cooling system stress during towing or slow-speed driving
• Heat buildup in aging factory-style cooling systems
• Need for an all-metal replacement radiator
• Fitment replacement for a damaged or leaking radiator

Installation Notes and Tips

Verify inlet and outlet orientation before installation: inlet is 1 1/2 in. on the left and outlet is 1 5/8 in. on the right. This radiator is a down-flow design and does not include a cap. For the listed Toyota Land Cruiser and Lexus LX450 applications, use a Mini 13 psi cap for proper fitment. Confirm clearance for the integrated oil cooler and compare dimensions against the original unit before final assembly.
