Detailed Description

OSC part number 1522 is engineered as an OE-style radiator replacement for vehicles equipped with engine oil cooling and transmission oil cooling. The radiator uses cadmium-plated tubes inside and out to help resist premature failure, and the core, tanks, and related components are selected for durability and consistent thermal performance. The design follows original cooler architecture where applicable, including plated cooler construction rather than substituting a different cooler style.

For 1999-2000 Cadillac Escalade and 1994 GMC Yukon applications, this radiator is built to match factory fitment expectations while addressing common wear points found in higher-mileage cooling systems. The multi-fit engineering approach is paired with factory-spec component placement and torque control to help maintain proper fit and sealing. Part number 1522 is also cross-referenced to APDI 8011522 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Reduced cooling efficiency from clogged or weakened core passages
• Transmission fluid temperature concerns related to a failing cooler circuit
• Engine oil cooling issues caused by worn cooler components
• Overheating caused by degraded fins, tubes, or internal flow restriction

Installation Notes and Tips

Verify the core dimensions, inlet and outlet sizes, and cooler configuration before installation. This unit is a crossflow radiator with integrated oil cooler circuits, so confirm that the vehicle uses the same cooler layout and the 1-1/4 in. core specification. Inspect hoses, clamps, and mounting points for wear before transferring the new radiator into service.

Because the radiator is pressure tested during production, installation should focus on clean sealing surfaces and correct hose alignment. Follow factory service procedures for coolant refill and system bleeding to help prevent trapped air and temperature fluctuations after installation.

Quality Assurance

OSC states that each radiator is tested multiple times during production, including cooler testing before tank installation, core testing before assembly, and a final assembled-unit test. The design is built to OE-style standards for fit, function, and cooling-system reliability.
