No matter what happens, do not pour your old antifreeze down the drain. Despite the fact that it is somewhat diluted by water in the engine, antifreeze contains toxic chemicals like ethylene glycol, propylene glycol, and methanol — all of which are toxic to humans and animals alike.
First, antifreeze would be considered hazardous waste if it is mixed with a hazardous waste (such as gasoline). … Thus, even though the antifreeze may be hazardous, it is not considered to be a hazardous waste because the antifreeze is returned to its original use as a coolant.
It is now illegal to dump antifreeze down drains, into toilets, or discharge it into a sewer. In addition, California instituted a law in 2005 that required a bittering agent to be added to all antifreeze sold in the state so animals or humans would be less likely to ingest it.
You can also contact are your local recycle center, local government, mechanic and automotive shops for help with used antifreeze disposal. Earth 911’s Recycling Locator is a handy searchable database. Just click “antifreeze” and type in your zip code to find recycling facilities in your area.
Oil, antifreeze, and paint should always be properly recycled or removed. Hazardous waste should never be placed in your home garbage for pickup, or poured down the drain or in your backyard.
Antifreeze doesn’t evaporate, but the water does. BUT only if it is exposed to atmosphere (leak). It may not end up as a puddle on the ground; it may be leaving through the exhaust. But it’s still a leak.
Both propylene glycol and ethylene glycol are biodegradable and will soon break down into carbon dioxide and water.

In California, it is illegal to dispose of antifreeze in the trash, ground, or storm drains. … Recycling antifreeze conserves the earth’s limited natural resources by reclaiming glycol.
Aside from being toxic, ethylene glycol is also damaging to a septic system. … The propylene glycol or ethanol used in RV antifreeze, however, are both safe for your septic system and won’t cause any damage when used in appropriate quantities.
What About Contaminated Oil? Certified used oil center managers will not accept used motor oil that has been contaminated with other fluids such as antifreeze, solvents, gasoline, or water. So please, do not mix your used oil with anything.
As the engine gets old, the Coolant evaporates more and more. As a usual calculation, it is found that for every year an engine passes by, the coolant level drops to 0.25″ in 4 months provided that the engine is functioning well and with no leakages or damages.
Water boils at 212°F at sea level atmospheric pressure. When mixed 50-50 with glycol, the boiling point increases to around 226°F. The back of a bottle of antifreeze will state a boiling point of 256-260°F which is calculated after taking cooling system pressure into account.
When ethylene glycol antifreeze comes into contact with grass or plants, it can be devastating to the health of the soil and the plants or lawn grown in that soil. … Over time, antifreeze breaks down into corrosive acids, becoming contaminated with heavy metals, fuel and other substances from the vehicle’s engine.
If antifreeze is spilled on grass, it can kill it, which is one reason homeowners are encouraged to take precautions to avoid spills and leaks. … Used antifreeze also contains contaminants such as lead and benzene, all of which can cause further environmental problems to plants and water.
If the antifreeze is found to contain lead or other hazardous constituents above regulated levels, it is hazardous waste and is subject to hazardous waste management requirements for on-site handling, transportation and disposal. Montana: No clear policy on recycling of used antifreeze.
Some of the contaminants that may be present in used antifreeze are benzene and heavy metals such as lead, mercury, cadmium, chromium, copper and zinc. Don’t change your antifreeze until it’s necessary. … However, used propylene glycol may still contain some hazardous containments (gas and heavy metals).
Overview of the Hazardous Waste Identification Process
EPA’s regulations in the Code of Federal Regulations (40 CFR) define four hazardous waste characteristic properties: ignitability, corrosivity, reactivity, or toxicity (see 40 CFR 261.21- 261.24).
Winterize the pipes
Shut off the water main and open all faucets to let them drain. Flush the toilets a few times until the water no longer fills the tank and bowl. Drain all appliances, including your water heater. Completely empty your septic system’s pressure tank.
Yeast helps actively breaks down waste solids when added to your septic system. Flush ½ cup of dry baking yeast down the toilet, the first time. Add ¼ cup of instant yeast every 4 months, after the initial addition.
drain water out of tank
With the system completely charged, hold down the flush handle. The water will drain out of the tank, and air will start coming through the pipes, which cleans out the ball cock. Hold the handle until all the water is out of the tank, and then let it go. Finally, shut off the valve.
Your Engine’s Cylinder Head Gasket is blown. This is causing the engine to consume/burn the coolant. This is the reason your coolant auxiliary tank is always empty. The boiling out of water also happens due to this.
When you are losing coolant but no leak is visible, several parts could be the guilty party. It could be a blown head gasket, a fractured cylinder head, damaged cylinder bores, or a manifold leak. … However, you may breathe easy if the mechanic does not find any trace of exhaust gases in the coolant.
If you’re antifreeze keeps running out quickly, you’ve almost definitely got a leak. … Sometimes a leak may not be visible. Even if you have depleted coolant levels with no sign of leakage, you could still have an internal leak that isn’t detectable from the outside of your engine.
While water does help to keep your engine cool, it does not work nearly as well as coolant does. First of all, water boils faster and at a lower temperature than coolant. If it is winter, then you risk having your engine block crack if you run your engine with only plain water.
The coolant would boil out of the radiator when you remove the cap regardless of any other problems. The coolant system is kept under pressure to prevent the water from boiling – that’s why the cap clearly states “do not remove while hot”.
One of the most common causes is a blown head gasket, in which the air pressure inside the cylinder heads is transferred to the cooling system. This escaped air causes bubbling in the coolant/antifreeze reservoir, which can often be mistaken for boiling.
