COOLING SYSTEMS


Products & Services - Cooling Systems
The cooling system of any vehicle is by far the most important component of the entire machine. It is a fact that between 60 and 80% of engine and transmission failures are caused by cooling system "malfunctions". This has been an enormous cost to equipment owners and $1.5 billion dollars annually is attributed to this failure across Australia.
This is an enormous amount of money considering the fact that it could be reduced dramatically (probably by 75%) by the installation of the correct cooling system products.
FluidMasters ongoing commitment is to offer the very best cooling system products that can be produced. The products FluidMasters market were developed by the School of Chemical Engineering at the Western Australian Institute of Technology (Curtin University) in the early 1980's by Dr Richie and his team developed a protectorate as well as a flushing product.
FluidMasters have been marketing these products to their client base since 1982 and in that time the two most common and most destructive problems confronting the operator as far as the cooling system is concerned are "Cavitation Erosion" (Pit holes that drill through the cylinder liners) and "Electrolysis" (the destruction of alloys, i.e. cylinder heads etc).These two major problems have become a thing of the past for our clients with not one instance being recorded in over 26 years.
The design of cooling systems today is as it was in Henry Ford's time, with very little changes. Water, a radiator and radiator hoses, fan belts, a radiator cap, and a water pump.
In engines today it is essential to protect complicated alloy heads and multi valve systems. An alloy head is subjected to "electrolysis", the disintegrating of alloy by electrical action of the engine. It is as though the engine is one big "battery". An alloy head can cost anywhere from $1000.00 to $6000.00.
Scary thought but a reality, and still they go unprotected as owners take the advice of the repairer or the garage owner who sells them the incorrect or inadequate product for their equipment's cooling systems. Remember, the retailer usually has little knowledge of the products he is selling.
So, why is it that FluidMasters can advise you on the correct products for this protection? Because, we manufacture our products to perform as required by the manufacturer. Sadly though, MANY of the OEM engines cooling system protection just DO NOT WORK, or fail before the stipulated time of protection is reached.
Diesel Engine manufacturers have increased engine operating temperatures to improve engine efficiency. This means proper cooling system maintenance is especially important. Overheating,overcooling, pitting, cavitation, erosion, cracked heads, piston seizures, and plugged radiators are classic cooling system failures.
Proper coolant selection and maintenance of the system is the owner's choice and the right coolant is vital to successful engine service life. In fact, coolant is just as important as the quality of your fuel or lubricating oil.
FluidMasters provides cooling system preventative maintenance products and services to help you avoid the down-time & costly effects of coolant-related engine / transmission failures.
Our Cooling System maintenance products include:
Cooling System Conditioner
Cooling System All Seasons Coolant
Cooling System Flush (Please note that we provide onsite services for cooling systems)

Stray Current Corrosion Test Results
Purpose: to evaluate the corrosion effect of minor voltage in cooling fluid under controlled and measurable conditions. A leading brand coolant was chosen for the test as it has a known and proven level of performance without the presence of voltage.
Test method used and modifications made
The test method chosen for evaluation of the effects of stray current corrosion was ASTM D1384-87. This test method is recognized world wide as a basis for evaluating the corrosion potential of a cooling fluid on the six basic metals found within the cooling system. Two tests were run using identical coolant. This fluid was chosen as it is known to perform excellently under this test method. Test setup ONE was in accordance with standard ASTM D1384-87 requirements for testing coolants. Test setup TWO was modified to include voltage leakage commonly found in faulty automotive cooling systems. The test coupons are in two insulated bundles. (Copper, Solder, Brass) and (steel, Cast Iron, Cast Aluminium). Positive voltage was induced on the Solder Coupon and the Cast Iron coupon to ensure both sets received the same voltage flow. All test metal coupons were new and certified to conform with the material specification of ASTM D1384-87. Both tests were run over 336 hours at 900 c with aeration of 100 ml per Minute.
Results and Conclusion
The results were staggering; Test ONE with no voltage present was inline with all previous tests of the brand name coolant (Virtually no metal corrosion weight loss on any coupons). Test TWO with 1 volt present in the coolant suffered massive corrosion and weight loss on Solder, Cast Iron and Aluminium. Both Cast Iron and Cast Aluminuim were the most sensitive to stray current increasing in corrosion rate to a thousand percent over the standard test with no voltage, Aluminium pitted badly, Solder's corrosion rate increased some 500% when voltage was present. Copper, Brass and Steel showed a minor corrosion rate increase in the presence of voltage but still fell well within the corrosion performance level required by ASTM D1384 We also noted a marked increase in the conductivity of the coolant at the end of the test that was subjected to Voltage, this indicates that the fluid is taking on corrosion by products and further enhancing the effect of voltage corrosion. Stray current is obviously a major corrosion problem where Cast Iron and Aluminuim are present regardless of coolant type.
Stray current tests
This Test had 1 volt induced into the cooling fluid. Note Severe corrosion and pitting on Aluminium & Cast iron. Bottom set of metal coupons are from Test 1. This test was performed using the same cooling fluid as test 2 minus the voltage. The results were near to perfect with no pitting or corrosion weight loss on any of the 6 metals. The initial results indicate that no matter what cooling fluid is used if voltage is present in the cooling system accelerated corrosion of Solder, Cast iron and Aluminium will occur. Also we noted that any cooling fluid including water will actually increase its conductivity as a result of voltage leak and continue to enhance the Stray Current corrosion loss on all metals. Voltage induced corrosion is a MAJOR PROBLEM and cannot be ignored any longer as it is causing motorists Millions of unnecessary dollars per year.
