Detailed Product Overview

One Stop Solutions 13395 is an OSC radiator built with premium-grade tubes, fins, headers, tanks, and related components for durability and consistent cooling performance. Factory-spec fitted and torqued components help maintain OE-style fit, form, and function, while engineering updates are used to address common failure points found in higher-mileage vehicles. The radiator core is tested before assembly, the transmission and engine oil coolers are tested before installation into the tank, and the completed unit is tested again after assembly.

This radiator is a direct replacement for BMW cooling system service where a crossflow layout, plastic tank construction, and OE-style dimensions are required. It cross-references BMW 17117600520 and BM3010174 for the same application. Part Number 13395 is also listed as CU13395.

Common Cooling System Issues It Can Address

• Coolant leaks from a cracked or aging radiator tank
• Restricted cooling performance from a worn or damaged core
