TYC Radiator Product Line Details

The TYC Radiator product line focuses on delivering quality cooling components that meet or exceed OEM specifications. This line emphasizes durable aluminum cores and integrated transmission oil coolers where applicable, such as in part number 2356. The design supports efficient engine and transmission cooling, contributing to vehicle reliability and performance.

Technical Specifications and Features

This radiator features a downflow flow configuration, which directs coolant downward through the core for effective heat exchange. The core consists of a single row of 70 tubes measuring 26 by 2 inches, paired with 73 fins every 4 inches to maximize cooling surface area. Both the top and bottom headers measure 2.01 by 29.13 inches, ensuring structural integrity and proper coolant flow. The integrated concentric transmission oil cooler uses tube fittings with 0.39-inch inlet and outlet diameters, facilitating transmission fluid cooling without the need for a separate cooler.

  • Replaces faulty or leaking radiators in Lexus IS300 models
  • Addresses overheating issues caused by inefficient engine cooling
  • Improves transmission fluid temperature control with built-in oil cooler
  • Resolves coolant leaks from damaged or corroded radiator cores
  • Supports engine performance by maintaining optimal operating temperatures

Installation Notes and Tips

Installation requires proper handling of hose clamp connections with 1.38-inch diameter inlet and outlet ports. Ensure all coolant and transmission fluid lines are securely attached to prevent leaks. Verify compatibility with Lexus IS300 models before installation. It is recommended to inspect related cooling system components during replacement to maintain overall system integrity.
