Detailed Description

This Global Parts radiator, part number 13749C, is engineered for Mercedes-Benz cooling system service where a direct radiator replacement is needed. The aluminum core and plastic tank design are common OE-style materials for balancing heat dissipation, durability, and fitment.

This part cross-references Bosch (e.g., 13749) for the same application.

Common Replacement Reasons

• Coolant leaks from a damaged radiator tank or core
• Overheating caused by reduced heat exchange efficiency
• Visible corrosion, cracking, or impact damage
• Temperature fluctuation during normal driving
• Cooling system service on a Mercedes-Benz SL550, SLC300, or SL450

Installation Notes and Quality Assurance

Verify core dimensions and connection points against the original unit before installation. Inspect hoses, clamps, and adjacent cooling components during replacement, and refill the system with the correct coolant specification for the vehicle. Because this radiator does not include a cap, thermostat, or internal transmission oil cooler, reuse or source those components separately as needed for the application.

Global Parts 13749C is listed with OE-style fitment coverage for the vehicles shown above and is supported by the brand’s radiator application data for these Mercedes-Benz models.
