Product Overview

The coolant hose, OEM number A2465010258, runs from the transmission cooler to the radiator on the Mercedes-Benz CLA250 (2014-2019), GLA250 (2015-2020), and B-Class (W246, 2014 onward), all sharing the same 2.0L turbocharged 4-cylinder platform. Since this hose spans three closely related Mercedes-Benz compact models, it's a high-turnover part number worth stocking in volume for distributors serving this platform.

A worn or leaking coolant hose typically shows up as visible coolant leaks, low coolant level, or engine or transmission overheating. GSK Auto manufactures this hose to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

What Is a Transmission Cooler Coolant Hose?

Function: This hose carries coolant between the transmission oil cooler (integrated into the radiator assembly on this platform) and the engine cooling system, helping regulate transmission fluid temperature using the coolant circuit.

Working Principle: Coolant circulates through this hose as part of the transmission cooling loop, transferring heat away from the transmission fluid via the radiator's integrated cooler section.

Importance: On a compact turbocharged platform, a properly sealed coolant hose is essential for maintaining both engine cooling system pressure and transmission temperature control.

Common Failures & Signs: Visible coolant leaks near the hose connections. Low coolant level from a slow leak. Engine or transmission overheating. Sweet coolant smell noticeable near the engine bay.
