coolant in oil?

[nsrchofpwr]

does antifreeze attack the material that the engine bearings are made of if it comes in contact with them?

Uh, why is there antifreeze in your oil? Did you blow your Head Gasket!

no, not me mine runs great! (knock on wood). i am in another post on this site and thougt that i learned this along time ago but do not remeber where or when. also as i gain wisdom i want to research this idea to see if it was or is b.s. or not.

I dont think it does. I have read on here about people blowing thier HG and still driving the truck for short periods untill they can get it in to the shop. I dont think I would try it though. There are places in that engine that antifreeze just isnt supposed to go!

any one else??????????

[Tony V]

I'd go with his advice. Its probably right!

i think i am going to get a bucket, put one in it with some antifreeze and see what happens. no where near the same conditions because of heat and oil mixing etc., but i will see.

Ethylene Glycol (the main ingredient in coolant) and oil don't react together, so nothing is "attacking" anything else. Subjecting your bearings (or any other surface area that needs lubrication) with any liquid or solvent, which doesn't have any lubricating properties is a bad idea, but for short periods of time, you won't see any residual effects from it.

If you get a little water in the crank case due to condensation, or like on my tractors, get a bit of rain down the exhaust pipe, it will evaporate when the engine gets warm. No major problem.

Now, some old school mechanics I know say that actual coolant (ethylene glycol) is very bad news. It doesn't evaporate like water, and it is even less lubricating than water, so if you get it in your bearings, there is *no* film of anything keeping the metal off the metal. Bad things happen quickly.

So, water is not good by any means, but coolant is worse.

Just look at the foamy mess that oil turns into with a bad HG and that should pretty much tell you everything you need to know.
