2012 DL1000 Vstrom. Nearest Suzi dealer 120 miles away. Would like to drain and refill my system, since I bought the scoot used and do not know the last time the coolant was changed. Do not want to drive to the nearest Suzi dealer (120 miles). What is a reasonable and logical substitute? Suspect that you old timers to this site will find this query to be redundant, so I apologize in advance. CC

I use Zerex asian long-life 50/50, but any modern coolant will do. Try to find one that is silicate free, as this is a scrubbing agent that will unfortunately accelerate wear on the plastic impeller of the water pump. The coolants sold at motorcycle shops are usually overpriced.

I use Zerex Asian as well. It is pink and the previous antifreeze was blue or green (I forget) and PO didn't know what her mechanic used. I flushed the system with a gallon of distilled water to flush the old AF out before adding the Zerex and all is well.

Color of the antifreeze AKA glycol is no indication of what it is (propylene or ethylene base) or the concentration. You can use any silica free (it will state this on the label) antifreeze you want. The only thign you can;t dois mix propylene and ethylene glycol's together. Since you are doing a 100% change I would suggest good old Prestone 50/50 premix. Cheap, reliable and silca free.

Don't get caught up in the buzz words like "Zerex Asian" or Motorcycle" and pay 2 or 3 times as much for the same thing minus the buzz words. Look up the MSDS/SDS and you will see there is no difference.

Glycol comes in 2 bases:

Propylene = vegetable oil bases and environmentally friendly. You actually eat many food products containing trace amounts of propylene glycol.

Ethylene = Alcohol based and poisonous to humans and animals

Which is why I recommended flushing with distilled water if you don't know what is in there and replacing it with something new.

If Zerex was 2-3x more expensive than Prestone I would have gone with Prestone. It was a couple of bucks more per gallon than the cheapest AF a couple of years ago when I did my radiator flush and I recently saw it on sale at my local auto parts store for around $13.

If anyone is concerned about spending too much on antifreeze....

Stay away from the "50/50" premix jugs! Go buy a gallon jug of DISTILLED water for under $1.30 about anywhere. Then you have TWO gallons of antifreeze to use for nearly the same cost.

It really works out to 100% antifreeze (Prestone is $10.87 per gallon) and 1 gallon of distilled water ($1.30) produce a 50/50 mix at a cost of $0.05 per ounce. Buying 50/50 premix (Prestone is $8.87 per gallon) is $0.07 per ounce. While I can't argue the fact that premix is more costly 50/50 at a $0.02 premium per ounce I'll spluge for the convenience.

In addition, I would question whether you're really getting distilled water at that price. The process of distilling water has to be more expensive than filtered "drinking" water. Sure, the label says distilled, but that may be just a marketing term, like the "synthetic" oil that isn't really polyalpha olefin.

Likewise. The time it would take is way more valuable to me than the $1.50 (and that's probably a huge overestimate!) I'd save mixing it myself.

I've done the mixing myself with coolant for my car. Pain in the butt. I didn't make that mistake after I bought my Vee.

Back to the OP's point: yeah, like others are saying, anything that's safe for aluminum radiators & engines will work, and preferably silicate-free. It certainly doesn't have to say "motorcycle" on the bottle, and those that do are generally overpriced.

I was using Zerex Asian for about the first half of this year. Will switch back next time I can be bothered to do a complete coolant replacement. Would still be using Zerex, except that back in July, I was basically forced to get an unnecessary coolant replacement by an unscrupulous and/or ignorant (take your pick) dealer (details here: http://www.stromtrooper.com/general-v-strom-discussion/377953-finding-motorcycle-mechanic-who-actually-knows-what-hes-talking-about.html).

Zerex Asian is a few more bucks per gallon vs. some of the green coolants. I went with the Zerex Asian because it was the easiest one to find that was silicate-free and not too expensive.

FWIW, it doesn't matter at all whether you use the blue Zerex Asian or the red Zerex Asian. They are identical apart from color. The color is simply to meet different manufactrers' specs (apparently, some specify the color!).
