Yes, the EnviroCool Cleaner Filter uses the same basic cleaning technology that has been used in the industry for years. The major difference is that the EnviroCool Cleaner Filter does not require draining and flushing the system

Yes and no. EnviroCool does not use phosphates in any of its products because phosphates are a major cause of dissolved solids problems, nor does it include any inert binding agent as some pelletized chemicals do.The level of dissolved solids will, however, increase after using the EnviroCool Cleaner Filter. This is because the chelating agents in the cleaner re-liquefy the minerals original in the coolant which had plated out as scale on the walls of the cooling system. Those minerals then flow freely throughout the engine without harming seals, liners, etc.

The chelating agents used in most of the cleaning products are very aggressive cleaners when in an acidic system. However, by maintaining a high pH solution (9.5 to 10) the chelating agents become controlled and manageable. The EnviroCool Cleaner Filter takes advantage of this basic chemical principle to provide you with an easy, cost-effective means of maintaining your cooling system.

No, you simply need to bring the pH back up into the accepted range. The easiest way to do this is to add a liquid SCA package. Then just spin-on the EnviroCool Cleaner Filter. After using the EnviroCool Cleaner Filter you must maintain the inhibitor level in the 9.5-10 range. When the inhibitor level drops, corrosion begins to form within hours.

No, the recycling systems on the market today are designed to remove impurities from the coolant. They are not primarily intended to clean hardened scale and corrosion from the walls of the cooling system. In fact, the EnviroCool Cleaner Filter complement s the use of a recycler. First, use the EnviroCool Cleaner Filter for a month to re-dissolve any mineral deposits which have formed. Next, use a recycling system to remove the dissolved solids from the liquid.

No, the EnviroCool Cleaner Filter will not harm any of the materials in the engine. See the ASTM tests. The EnviroCool Cleaner Filter may, however, remove some stop leak products.

EnviroCool uses the same chemical ingredients as most engine cleaners. The main difference is that the EnviroCool Cleaner Filter is concentrated and is introduced into the cooling system via a spin-on filter. No draining or flushing is required. Present cleaners are all liquid and require draining, flushing, dilution and/or mixing.

To use the EnviroCool Cleaner Filter , you must test the coolant first for inhibitor and antifreeze levels (a test kit is included in the filter package.) If the inhibitor or antifreeze level is not satisfactory, liquid make-up such as Nalcool 2000, Cool-tech, or Fleetguard DCA is necessary to bring the level up. EnviroCool has included in its formulation film formers, anti-foams, pH buffers, as well as concentrated chelant cleaners. These protective chemicals, such as nitrates (for aluminum protection), Tolytriazole (TT, for red metals), borate buffers (to maintain alkaline pH), and Pluronic L-61 anti-foams (to stop cavitation corrosion) are effective as evidenced by the independently conducted ASTM series of tests.

Even though the EnviroCool pellet formulation is different, it does not have any ingredients that have not already been in use in engine cooling systems. All the chemicals used in the EnviroCool Cleaner Filter are biodegradable or naturally occurring. This was done specifically to counter any OEM questions and/or opposition to the EnviroCool Cleaner Filter.
