This heater coolant line with OE number 2538308801 is suitable for 2016–2022 Mercedes-Benz GLC-Class (GLC300 for home use, GLC43 AMG 4MATIC for performance) with X253 chassis, compatible with E-Class W213 models in the same period, and undertakes the coolant transmission of the cabin heater circuit.
Made of upgraded EPDM rubber raw material, this hose resists continuous high temperature in the engine bay and chemical corrosion of coolant, and will not harden and leak in low-temperature winter conditions. The pipe clamping and interface tolerances are in line with the original factory standards, the buckle installation position completely matches the original car sheet metal, and no loosening and friction damage of the pipe will occur after installation.
The product has passed the pulse water pressure aging and thermal cycle durability tests, suitable for home commuting, high-speed travel, and performance driving scenarios. It solves the common problems of weak heater heating in the car, excessive antifreeze consumption, and moldy floor mats caused by aging and leakage of the original heater hose. It meets the daily maintenance needs of family cars and the strict working conditions of AMG performance cars, and achieves the original-level replacement effect of the cooling and heating system at a high cost performance.
