Hello everybody,

last Saturday I changed the antifreeze. I don't know why, but for change I've selected Liqui Moly GTL-11. I saw "MB 325.0/325.2" (it's crucial for CRD engines from MB) on its label and bought 3 canisters.

Later that day I've checked http://bevo.mercedes-benz.com/bevolisten/325.0_de.html. I was perplexed that I haven't seen any traces of the antifreeze that I bought, on the list. The question is: should I dump the fluid and refill cooling system with the original - "orange" - antifreeze from Mopar (Chrysler, Fiat etc)? They say their product is "fully compliant or supersedes any original antifreeze" but in that case why MB knows nothing about it?

I used to trust Liqui Moly (I use their motor oils and lot of other stuff), and this case is something unprecedented for me. What do you think?

I've read. So, I think I should drain it out and refill with the G-05/MS-9769 compliant coolant. Thanks

The only aftermarket equalivalent for Chrysler HOAT that I am aware of is Zerex G-05.

There may be others, but no one makes that clear on their labeling, as well Prestone's "All Makes, All Models" labeling is outright deceptive. The best thing you can say about Prestone's antifreeze, that is very close to the same as GM Dexcool, is that it hasn't damaged your vehicle "YET". Don't use it.

I don't know anything about Liqui Moly GTL-11, but unless the bottle clearly states it is HOAT antifreeze for use with Chrysler vehicles recommending HOAT antifreeze, I would NOT use it.

Yes, there is an argument that if you drained and flushed the cooling system completly, i.e. a total replacement without mixing with the old antifreeze, just switching to another type of antifreeze, it should work as intended. Most modern vehicles have removed the things in the cooling system that are incompatible with some types of other antifreeze.

But, you don't know that for a fact, so there is always a risk, so the safest policy is just use exactly what is recommended for the most reliable result.

I don't think I have to tell you, but for the benefit of others, never mix different types of antifreeze (and sadly most aftermarket antifreeze do NOT state what type they are on the bottle and often make misleading claims like they are for "All Makes and Models"), unless you know exactly what they are and know for a fact they mix, NOT relying on claims from marketing hype. Some different types mix, but won't work as well when they are mixed and others are outright incompatible to mix (even though the bottle claims there are) and will cause problems if they are mixed.

Thanks for reply, I already replaced that blue sht with genuine Mopar 5 year/100K miles concentrate. Sure, after flushing with 5 (~20 litres)gallons of distillated water.

Btw, is it okay that two different canisters of that concentrate are of different colors? One was a sort of acid red, and other one was slightly yellow. Both were bought from trusted seller.

Do they both have the same part number ?

No, they do not. That is of red color has the 68048953AA number, and light yellow ended with EC (as far as I remember). Both have had MS-9769G labels.
