Having problems with your 1999 Mercedes-Benz E-Class ?
Confusion as to how often to replace engine coolant.
\015 Mercedes WIS says to change coolant for my 1999 E430 15 years or 250,000 KM but my service booklet says every 3 years and no mileage limit is mentioned. Which is the correct maintenance period?\015
15 years is way too long to change coolant. i'd go with 3.
