Do I need to use snowmobile coolant or can I use an auto grade? Should I mix with water or use it straight? Thankx in advance.

I use the stuff we pour in our tractors, from John Deere, never caused a problem. We use that stuff in cars/trucks/tractors/combine/sleds/4-wheeler

basically everything, so I don't think auto stuff would cause any issues.

I don't think there are any special coolants for snowmobiles, most call for a high quality ethylene glycol antifreeze. Mix it in the ratio recommended by the sled manufacturer, probably around 60/40.


TIPS:

- use distilled water, it will reduce corrosion.

- using more antifreeze isn't better, antifreeze doesn't conduct heat as well as water.

- don't use the orange coolant (GM DexCool), it has a tendancy to turn to sludge when mixed with regular (green) coolant.

- make sure you properly air bleed your cooling system.

What's the difference between green and orange anyway? I thought that it was just a different color so they could charge more for it...

I believe the orange stuff is silocate free. I use it in my Magna for reasons I no longer remember, other then I'm supposed to.

Orange "DexCool" contains nitrite.

Green coolant contains silicate.


Orange coolant is usually "DexCool", I believe that there was also an orange factory fill coolant that Chrysler used that wasn't DexCool.

DexCool has a different chemical inhibitor package than regular coolant. It can turn to a brown sludge when mixed with even small amounts of regular (green) coolant. When the two types are mixed there is also a potential problem with aluminum corrosion.

ONLY use "DexCool" when recommended by the manufacturer, GM and Caterpillar both use it, I think GM started using it around 96/97.

Wow, I never knew any of that. I'll keep that in mind. I think my friend's truck has orange stuff, he wanted to dump green in on top of it, and we advised him against it.

Yes only use orange in G.Ms and always mix your anti-freeze. Pure anti-freeze will freeze! It has to really cold but will freeze, mixture is about 60-40.

Definitely use distilled water and no more than 60% anti/40% distilled. I use the 5-yr Texaco stuff and have had no problems.
