Hear that dreaded clicking sound but your engine won't turn over? Your starter motor might have given up. This is a direct replacement starter for certain Mercedes-Benz models (C300, E300, GLC300, etc.) and Infiniti Q50/Q60 models. The key specs: 1.7 Kilowatts of power, 12 Volts, Clockwise rotation, and a 13-tooth drive gear. VERY IMPORTANT: The listing says it ONLY fits the 2.0L L4 (inline 4-cylinder) engine. Do not buy this for the V6 models listed, even though they're mentioned. It replaces OEM numbers like 2749060400. It's an unbranded part but comes with a 1-year warranty and has the Prop 65 warning. Installing a starter is a moderately involved job, usually underneath the car near the transmission. A new starter will get you cranking strong and reliably again. Double, triple-check your engine size before ordering to avoid the hassle of a return.
