Coolant-Genuine Mercedes
BLUE Coolant/Antifreeze-G48 OEM ZEREX
Rating: 0
Zerex/Valvoline 1 gallon (concentrate) container, to be diluted in equal parts with water, for a 50/50 mixture.
This Mercedes approved OEM G48 formula is HOAT, or Hybrid Organic Acid Technology and meets Mercedes Spec 325.0 (concentrate) and 326.0 (pre-mix)

This is BLUE in color, low acid, low silicate and phosphate-free.  Check the existing color of your coolant.  DO NOT MIX WITH YELLOW COOLANT.
This is the latest formula which replaces both Q1 03 0002 (yellow/gold) and Q 1 03 0004 (blue).
If you have the old fluid (NOT BLUE), it will require a complete drain and flush, as the old fluid Q 1 03 0002, has been discontinued and superseded by this blue fluid. 
Do NOT mix the two different colored fluids together, as they are not compatible.

Zerex from Valvoline is the #1 selling OEM-approved coolant brand. Zerex G48 Antifreeze/Coolant is proven to maximize engine life in cars and light trucks. Its premium formulation is suitable for Mercedes-Benz engines. Specially formulated with NAP-free Hybrid Organic Acid Technology (HOAT) in an ethylene glycol-base, Zerex is made for your car and protects better than industry standards against corrosion, leaking, deposits as well as freezing and boiling – the four main causes of cooling system failure, which is the leading cause of engine breakdown. Our lower-silicate, reduced pH, phosphate-free formula with Hybrid Organic Acid Technology (HOAT) protects all cooling system metals (including aluminum) from corrosion. It contains nitrites that protects diesel-engine cylinder liners from cavitation, while deposit control additives guard against hardwater deposits and scale. So radiators, water pumps and other metal cooling system parts stay clean and your antifreeze flows and functions properly. Whether you’re topping off your radiator or doing a complete system flush, trust Zerex G48 Antifreeze/Coolant. Made for your car. Made by Valvoline.
