Radiator for Cadillac SRX

Replace a worn or leaking cooling unit with this OSC Premium radiator, engineered for OES form and function. This radiator is built for the 2007-2009 Cadillac SRX and uses premium-grade aluminum construction with plastic tanks for a direct-fit replacement.

  • Fits 2007 Cadillac SRX, w/TOC
  • Fits 2008-2009 Cadillac SRX, N/A
  • Crossflow radiator design with a 1-row core
  • Transmission oil cooler included; engine oil cooler not included
  • Core dimensions: 23 5/8 in. height, 20 7/16 in. width, 1 in. thickness
  • 1 3/8 in. inlet and outlet diameters
  • Cadmium-plated tubes help resist premature failure
  • Die-cut gasket design helps reduce leak points

Built for OE-Style Cooling

Part number 13115 is engineered to match original equipment form, fit, and function while addressing common failure points found in higher-mileage cooling systems. OSC uses premium tubes, fins, headers, and tanks, and each radiator is individually pressure tested during production. The integrated plated transmission oil cooler and factory-spec component fitment support a clean installation in Cadillac SRX applications.

This part cross-references APDI 8013115 and Spectra Premium CU13115 for the same application.

Common Problems 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 related to a failing cooler circuit
  • Reduced cooling performance from damaged fins, tubes, or headers
  • Fitment issues after replacing a radiator with a non-OE-style unit

Installation Notes

Verify radiator dimensions, inlet and outlet sizes, and transmission cooler line spacing before installation. This radiator is a crossflow design and includes the transmission oil cooler; confirm your vehicle’s original configuration matches the listed Cadillac SRX fitment, including the 2007 SRX w/TOC application. Transfer any required vehicle-specific components during installation as needed.

Quality Assurance

OSC tests the transmission and engine oil coolers before assembly, tests the core prior to assembly, and tests the completed radiator again after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in high-mileage vehicles.
