Detailed Description

OSC part 1190 is engineered as a direct-fit radiator for Toyota Pickup and Toyota 4Runner applications listed above. It uses a premium aluminum core with plastic tanks and a concentric transmission oil cooler, matching the original cooler design where equipped. The radiator is built to factory-style dimensions, including 20 9/16" inlet and outlet header lengths, 2 5/8" header widths, and a 1 1/2" transmission oil cooler diameter with 10 13/16" fitting spacing.

This radiator is designed to address common cooling-system wear in older vehicles by using enhanced fin density, a thicker core profile, and durable internal construction. Part number 1190 is a practical replacement for a Toyota Pickup radiator or Toyota 4Runner radiator when the original unit shows leakage, reduced cooling efficiency, or transmission cooler concerns. This part cross-references Spectra Premium CU1190 for the same application.

Common Issues This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Corrosion-related radiator deterioration in high-mileage vehicles
• Fitment problems from previous non-OE-style replacement units

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizing, and transmission cooler routing before installation. This unit is a downflow design, so confirm the vehicle’s original radiator layout matches the application. Transfer and reconnect all factory-style cooling connections carefully, and inspect hoses, clamps, and mounts for wear before installing the new radiator. Part 1190 is built for a drop-in fit on the listed Toyota Pickup and 4Runner applications.

Quality Assurance

OSC tests the radiator core before assembly, then tests the completed unit again after assembly, with additional testing of the transmission and engine oil cooler circuits prior to installation into the tank. The design uses premium materials and factory-spec component placement to support consistent fit and cooling performance.
