I have been good about using Mercedes brand coolant for the om603.
The only other consideration was Getex G5 or something like that, when I was last looking.
But it's been a few years, and I see this on the market, an aftermarket (
Canadian Tire selling "OEM Premium") brand that is advertising car-specific applications.
This is what they have to say:
Designed for use in specific vehicle-makes
Recommended for BMW, Jaguar, Mercedes-Benz, Mini, Smart and Volvo vehicles
Low silicate OAT formulation
Nitrite, amine and phosphate free
Recommended change interval: Up to 250,000 km or 5 years service protection
50/50 pre-mixed, ready-to-use coolant
May also be used in gasoline or diesel engines
They also have this
diesel specific kind but does not list any brands of engines:
Low silicate, phosphate and amine free
Performance rated at 6 years or 960,000 km
For use in light- and heavy-duty diesel applications where an extended service interval is required
For all on-road trucks, marine and industrial stationary and mobile farm equipment
Meets performance specifications of ASTM D-3306, D6210, JIS K-2234 and TMC RP 329
What's the current thinking on coolant religion?
Any opinions on whether either of these are OK for my om603?
And what is "low silicate
OAT" anyway? I guess I'll google that.
