What kind of antifreeze are you guys using?

by **Fnschlaud4620** » Sat Mar 31, 2007 10:30 am

I use John Deere cool-gard, 50/50 premix
I also use Deere plus-50 engine oil

must be a farmer thing, we run 15-40 deere oil in everything gas or diesel.

Same here, we ran Case 15-40 in everything until we got our 2004 Infiniti G35x; we use synthetic in it.

Is there a certain kind of antifreeze for diesels? I need to get some today and a checker or Autozone.

Thanks

anti-freeze is anti-freeze as long as it is new and clean and mixed at the proper ratio any will do.

Anti-freeze is not just anti-freeze. There's dozens of sorts on the market.

The standard color for pre-2001 Chrysler vehicles is green. That's what all the first gens come with. It's got to be changed every 30,000 miles or 2 years to prevent corrosion.

Now all the companies use their own color of crap.
The OAT/ HOAT fluids are Orange for GM DexCool, Pink for Audi/ Volkswagon and Toyota, Dark Green for Honda, Caterpillar uses Red, Orange for Daimler/ Chrysler/ Mercedes, Fuschia for Saturn, Yellow for Ford. Then there's blue stuff for other European and Korean companies. I think that all of the off-colored stuff is good for 150,000 miles or 5 years.

Then there's the aftermarket stuff that you buy by the gallon that can be amber, light green or whatever color you can imagine. I think Prestone's new stuff is plaid and Peak's is polka dotted.

Some colors are compatible with others, some anti-freezes are only good in certain engines or radiators, some compatibilities aren't valid for given vehicles.

It would probably be worth it to put some of the newer stuff in your truck, just for convenience; I sure don't know enough to say which colors would be okay though. For what it's worth, Chrysler says not to do it. But there's always a chance that the previous owner filled his system up at whatever dealer his cousin worked at.

Most of the big antifreeze brands make now make a coolant that is compatible with anything. That means you can buy a gallon and use it to top off both anything form an 05 Chrysler to a 78 Ford.

I would use a coolant that is compatible with anything, but stay away from Dexcool.

Don't forget to add the additive for diesels. Helps prevent cavitation! I can't remember what it's callled. :roll:

I thought Cummins doesn't recommend any coolant additive? I also thought cavitation only matters in a wet-liner engine, because it causes the sleeves to get pitted? Please correct me if I'm wrong.

Two types, ethylene glycol based antifreeze and proplyene glycol based antifreeze. You want to use ethlyene glycol based antifreeze, not the other one. Just pick up any jug of AF and read the fine print.
