Heater Coolant Line OEM 2538308801 for Mercedes-Benz GLC X253 & E-Class W213 (2016–2022)
OEM heater coolant hose numbered 2538308801 matches Mercedes-Benz X253 chassis GLC-Class (2016–2022) and W213 chassis E-Class (2017–2021) passenger car models, supporting mainstream GLC300, sporty GLC43 AMG, standard E300 and performance-oriented E43 AMG trim grades. It transports heated engine coolant to cabin HVAC heater cores to deliver adjustable interior cabin heating throughout cold seasonal travel periods.
Compound-modified EPDM rubber construction grants robust thermal tolerance across a -40℃ to 125℃ operational spectrum, resisting chemical erosion from modern long-life antifreeze formulations and vibration fatigue originating from transverse-mounted Mercedes turbo powertrains. Dimensionally calibrated pipe bends accommodate constrained engine bay packaging layouts on contemporary M274 and M276 powerplants, removing assembly fitment obstacles.
Worn factory heater lines develop concealed coolant seepage over accumulated road mileage, diminishing cabin heating output, depleting coolant reservoir reserves, and generating windshield fogging from evaporating coolant vapor during winter morning commutes. Installing this factory-equivalent heater coolant piping restores full-volume hot coolant delivery toward heating hardware, delivers steady customizable cabin warmth across variable outdoor ambient temperatures, prevents unplanned winter-season roadside breakdown incidents, and elevates year-round occupant riding comfort for premium Mercedes-Benz passenger vehicles.
