different antifreeze

jeffcat · Oct 25, 2015

To mix up the old style anti freeze "Zerex" was Methinol mixed with water. I bought that stuff in the paint store many years ago and the blend I checked in a little cup in the freezer. Down to 10 below and didn't freeze. Mixed in some NAPA anti freeze boster and pump lube with rust inhibiter too. Anyone have a favorite blend they use? Don't want to use glycol type cause I am scared of getting it in the crank case.

Methanol

Use propylene glycol antifreeze . It doesn't boil off, ruin bearings or poison animals.

Gotta tell me where you get the stuff? Would NAPA know?

This is one source. Commonly used in RVs and other winterizing tasks where disposal is "down the Drain" Jim
One of many sources

Ahaaaa! So you mean some of this stuff can get in your crank case and you will not lock up the engine or spin a bearing? If so I will put some in Tomorrow! Thanks they have this at wally world.

I am not saying that at all. Oil is lubrication, antifreeze is not. When mixed with water, it is far from a lubricant. The RV material you are considering has no corrosion inhibitors, no water pump lubricant, no intended use as a engine antifreeze. Propylene glycol engine qualified brand name antifreeze is available. Please understand as soon as coolant begins to disappear, fix the engine. Jim

No on my CUB I had a tiny leak and put a little aluminum stop leak in her. All better and no leaks but I chickened out and put plain water with Napa treatment so it wouldn't rust or anything. Winter is coming and if the Sierra stuff is safe, like if a little gets in the oil or not? I will just drain her till spring time. I can do the head gasket then. As I said I mixed up the other stuff and used it in an old bull dozer cause we didn't know if we had any leaks. Worked just fine!

The reason we don't use alcohol base anti-freeze is it has a very low boiling point. In the unpressurized cooling systems of old it would just boil off during the summer so you had to add it back in every winter. In modern, pressurized cooling systems, alcohol will reduce the boiling point of the coolant to the point it will boil over at normal operating temperatures. That's why we use "permanent", glycol-based antifreeze.

If you worry about ethylene glycol in your crankcase, maybe you should fix that leaking head gasket. Water doesn't do a great job of lubricating bearings, either.

Had a tractor in the shop a while back that was leaking water. Cyl.head gasket was leaking externally. Put in a bottle of Mendite {liquid form} and leak sealed up.

Good stuff,wont plug rad.cores but does stop small leaks. I have used this many times over and I am sold on this product.

The first Hart-Parr tractors used oil as a coolant, it might have been a thremosiphon system. Do some tractor pullers run motor oil in their cooling system?

Amsoil sells the stuff. Propylene glycol is also sold from vendors in hot rod magazines. I would assume NAPA sells the stuff.
PG would not be in some low end store like Walmart. They are a lowest common denominator type of place.
