The ideal mixture is 50% water and 50% antifreeze. The coolant mixture should never contain less than 40% antifreeze or more than 60% antifreeze. The water used must meet engine manufacturer's guidelines for use in their coolant systems.

Water is half of the equation. Due to the variability of water around the country water with the maximum parts per million specifications are recommended:

Yes, KWICK KOOL will mix with, and improve the performance of, all existing radiator mixes, including the new extended life antifreeze. KWICK KOOL is not a replacement for antifreeze, but can be used in a water-only coolant environment such as racing or hot weather industrial settings where freezing is not a concern.

Using "hard" water out of the tap can cause scaling in the engine. Tap water is purified for drinking by chlorination, which kills germs but can cause corrosion in the engine. Even if you carefully measure the amounts of tap water and antifreeze to get the right blend, using tap water is not a good idea. Tap water also contains dissolved oxygen, calcium, magnesium, and other contaminates besides chlorine and chlorides that can significantly degrade corrosion inhibitor performance.

If there is any possibility that a rupture of the tubing could contaminate the potable water, use non-toxic propylene glycol. If contamination is impossible, automotive type ethylene glycol may be used.

Over a period of time, rust and corrosion will appear in the cooling system. Long term, this will reduce the life of cooling system components such as the radiator, water pump and coolant hoses.

Most manufacturers recommend a two-year interval. Some vehicles now have a long life coolant, which can last for four years.

No, all waste should be stored separately. Never mix any potential hazardous waste with another waste. If the antifreeze happens to be hazardous it would contaminate the entire container of used oil leaving the responsible party with hazardous waste to get rid of, which is much more expensive. Keep all wastes separate with the correct labels. Do not use disposable shop rags in certain processes at your facility.

Some drinking quality water does not meet engine manufacturer's specifications for the appropriate water for use in coolant systems. Most engine manufacturers have written water quality requirements. Customers should get these from them or use a coolant analysis program to determine suitability for use.

Small amount of top off coolant not meeting ES specifications will lower the overall SCA level to some degree based on the volume of top off between visits to your service shop. It is best to provide ES Coolant (or at least regular maintenance coolant like Compleat Premix) for top off purposes rather than let drivers or operators refill the system with incorrect coolant. If testing reveals that the SCA is significantly lower than 2.

Use a 50% solution of glycol based antifreeze solution to water for a system that must operate at very low temperatures. If only freeze protection is needed, a 20-25% solution is usually adequate because the more dilute solution forms a non rigid slush that will not flow well but will not damage the tubing.

We use chemically treated test strips (similar to ones used in spa/swimming pools) that change colour depending on the condition of the coolant.

Engine coolant is a generic term used to describe fluids that remove heat from an engine. Antifreeze is a more specific term used to describe products used to provide protection against freezing. Many people use these terms interchangeably, as we also do in this FAQ. Antifreeze (engine coolant) performs several functions in addition to providing freeze protection. Antifreeze contains chemicals that inhibit corrosion and scale formation in the engine and radiator.

Ans : Water has very good heat transfer property than other Coolant materials but it is also most corrosive material in comparison with other Coolant materials. The ordinary water always contains some dissolved minerals, so after evaporation of the water these impurities remain in Coolant & formed a Scale in Coolant System, thus reduced the heat transfer property of the engine. Therefore, 100% water has spoiled the coolant system due to corrosion & scale.

The coolant is typically a 50-50 mixture of water and some type of glycol (antifreeze). We do not recommend greater than a 60/40 ethylene glycol water mixture. Since we require changing the thermostat and coolant at least once a year or every 500 hours of operation, whichever occurs first we are concerned about the environmental impact of disposing of ethylene glycol which is highly poisonous and non-biodegradable.

If you mix antifreeze with distilled water at the ratio of one part antifreeze to one part water, you will have freeze protection down to ?34?F and boil-over protection up to 265?F (if using 15 PSI pressure cap). Never use concentrated antifreeze in a cooling system without adding water. At least 40% of the mixture should be water.

Using too much antifreeze or water in your engine coolant can harm your vehicle. Antifreeze concentrations higher than recommended levels can cause problems including corrosion, water pump failure, and increased engine wear. Increasing the concentration of ethylene glycol above 60% actually hurts the engine's freezing and overheating protection.
