Over charging or over concentrating a coolant system with additives will result in the formation of solids. These solids will form deposits that drop out and clog passage ways in the system preventing proper heat transfer. These solids are also very abrasive and will permanently damage surfaces they come in contact with. If a coolant filter is in use, it will be quickly plugged up.

Given the fact that literally thousands of fuel additives are offered on the market, engine manufacturers have no way of monitoring or testing the claims of so many products - making it difficult to determine specific products that are safe to use. However, PRI chemistry does not alter any fuel specifications issued by engine manufacturers - specifications by which manufacturers judge whether or not a particular fuel affects safe engine operation.

Ford Engines Defined: A Small block Ford is within the 260/289/302/351 series. The Big Block can be either an FE (360/390/427/428, vintage 61-68) or a 385 Series (429/460) after '69. Each series is a completely different design. Most people don't know that there was quite a mix of engines (All FE series) put into the original cars. Side-oiler 427s were mixed with center-oilers and stock 428 Super Cobra Jets. See similar questions...

Coolant is what keeps your engine operating at proper temperatures. However as coolant ages, its efficiency slowly declines. Older cars had large radiators with excess capacity. Today's cooling systems are designed "just big enough". And a little deterioration can soon cause big problems. The two main ingredients in "coolant" are water and antifreeze. Antifreeze is ethylene glycol based, which basically never wears out. See similar questions...

It is very important to use the factory Volvo coolant in your engine. Volvo will not honor the warranty if any other coolant is used. See similar questions...

Always follow your manufacturer’s recommendations as outlined in the owner’s manual. Typically the cooling system should be flushed out at least once every two years or 30,000 miles. The best time to have this service performed is in the spring or fall. A flush should never be done as a repair for an overheating problem. See similar questions...

It is very rare that a gasoline or diesel engine has "never" experienced a failure of a cooling system component, or a related part that couldn't have been prevented with the proper use of SCA's and a coolant filter. Both the short term and the long term economic benefits of properly utilizing SCA's and coolant filtration far out weigh the low initial investment for the appropriate coolant products and their installation.

It depends. Today's vehicles come with two types of engine coolant. One that lasts for two years and one that has a lasts five years. However, both should be changed according to their cycles. The reason is electrochemical degradation. This occurs whenever the coolant is in contact with metal. It creates higher levels of acids which left alone can result in damage to the radiator, heater core failure and leaking head gaskets. See similar questions...

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. See similar questions...

Use of the GMOLS should be suspended until the engine has been repaired and the engine no longer leaks coolant. See similar questions...

Our mechanic suggest that you check the oil every day of use and check the transmission and coolant at least once every five daily uses. This also forces you to look at the engine and the surrounding bilge areas which will greatly help in finding any problems before they become serious. See similar questions...

We recommend you never mix ANY TYPE of coolant and antifreeze products. One reason is that propylene glycol and ethylene glycol do not mix well together. Another reason is that just because the base fluid may be similar, other additives and ingredients may not be. Just as you would not mix oils, and for the same reasons, you should not mix coolants and antifreezes. See similar questions...

Engine Ice Hi-Performance Coolant tm utilizes a base fluid called Propylene Glycol. This base fluid has been proven to be relatively harmless to plants, animals and the environment, while being an excellent base fluid for an engine coolant. We take this non-toxic base, along with various inhibitors and dilute it with the most pure water possible, Deionized Water. See similar questions...

Engine Ice Hi-Performance Coolant TM is pre-mixed with de-ionized water. The process of de-ionizing water eliminates all of the impurities that can do harm to your cooling system. Regardless if you are using tap, bottled, distilled, spring or R/O (reverse osmosis) waters, it can still contain minute particles of iron, magnesium, rust, lime and calcium. Many of these waters also contain chemicals, such as chlorine, fluorides and acids. See similar questions...

Engine Ice Hi-Performance Coolant TM has an excellent high heat capacity and thermal conductivity characteristic, which in testing, has proven to exceed the abilities of most (EG) coolants. It provides efficient & effective engine heat transfer. Engine Ice Hi-Performance Coolant TM is a proven product, with added environmental benefits to assure the longevity of your engine, and the world we play in. See similar questions...

Engine Ice Hi-Performance Coolant TM is formulated with propylene glycol (PG). As compared to the ethylene glycol used in most other brands, propylene glycol is far less toxic and safer for children, pets, and wildlife. Engine Ice Hi-Performance Coolant TM is also phosphate free (phosphates kill the smallest forms of life in the environment in addition to trees and plants). See similar questions...

Yes. However we do recommend the use of an additive free filter on all coolant systems to remove all solid and liquid contamination. Coolant system maintenance should always be done as a complete package to be most effective. See similar questions...

Modern engine oils and fuels are carefully formulated to offer the best possible performance over a wide range of operating condition. There are occasions where an additive not contained in the oil or fuel will improve performance in one respect or another. However, there are also additives that will cause harm to the system. If aftermarket additives are used they should be thoroughly tested and offer more proof of performance than simple testimonial letters or anecdotal evidence. See similar questions...
