![]() Have a meeting to inform everybody, change all your labels, adjust inventory and if necessary print out reminders to put in the cabs of your trucks and equipment. When doing something as big as a wholesale change in the coolants you use, it’s extremely important to communicate what you’re doing and why to everybody: mechanics, technicians, service truck personnel, operators and drivers and the parts and inventory department. The whole system is under stress.” Communicate, communicate, communicate You can also get water pump leakage and coolant system component failure. That leads to poor heat transfer and overheating of the engine. “You can get slushing of the coolant where it becomes thick and hard to pump around the system. Lower Maintenance CostsReduces engine coolant and additive costs by as much as 500 compared to conventional coolants. ![]() Factory-FillUsed as standard factory-fill for all Cat machine cooling systems. “The freeze point protection doesn’t keep getting better the more ethylene glycol you add,” says Dilley. Cat ELC is developed, tested and approved by Caterpillar to meet the same high standards as all Genuine Cat Parts. “But then their guys get in a hurry and dump pure concentrate into the truck.” That leads to concentrations as high as 80 or 90 percent, which won’t perform as well as 50 percent, especially in hot conditions. ![]() “Some fleets only want to pay for concentrate, because they don’t want to pay for the water,” says Granger. Most coolant manufacturers offer a premixed 50/50 ELC that you can add directly to your radiator without having to mix it yourself. If this is something you’re considering, consult with your coolant supplier. The only drawback is that it takes a bit longer for the full benefits of the ELC additives to take effect, says Snyder. The benefit of a conversion fluid is that you don’t have to spend the time to completely drain your cooling system and dispose of the old coolant. You simply drain out 10 to 12 percent or so of the conventional coolant and put in the concentrated additives to fill the system back up. This is a package of ELC additives that can be put on top of a system that has conventional coolant already in it. Some coolant providers also offer what they call a conversion fluid. (Or adjust up to whatever your freeze point protection requires if you’re working in cold climates.) Conversions You want to make sure you don’t get any air pockets in the system.”ĭilley recommends you find out what the OEM says is the volume of the cooling system, add half that volume of coolant and half water. Once you’ve flushed it, the filling up is critical. Purus Antifreeze/Coolant Heavy Duty Extended Life Formula (ELC) - 50/50 - RED - Ready To Use. “You have to make sure you drain everything. The detection of CI and AFA in WEFGM prospectively makes it a more cost-saving base fluid for WBEC than water.“A flush-and-fill has to be done in a careful manner,” says Colin Dilley, director of technology, Prestone Technology Center. If I cannot find Rotella ELC, what could I use to mix with my Red Rotella ELC coolant in my truck I think they have only pre-mix ELC at Walmart. The only one approved for CAt EC1 is Rotella ELC, with nitrite. There was no significant difference in these properties for the two samples (P < 0.05). It gets confusing with all the ELC coolant from Rotella. Cat Coolant Conditioners are formulated for use in various Cat machines to prevent degradation and changes of machine component physical properties. ![]() CI found were 12.25 and 22.51 mg/L of phosphates and 5.00 and 6.00 mg/L of nitrates, while AFA obtained were 5.29 and 2.38 mg/L of ethylene glycols and 4.74 and 2.15 mg/L of propylene glycols from the 2 samples, respectively. The result for CF in the 2 samples, respectively, revealed pH values of 2.82 and 2.67, conductivity of 19 µs/cm, Pb of 0.06 and 0.05 mg/L, and Zn of 0.74 and 0.89 mg/L. In the analysis, atomic absorption spectrometry and other methods were used for CF colorimetric methods using a spectrophotometer was used for CI, and gas chromatography/flame ionization detection (GC/FID) was used for AFA. Two samples of WEFGM, decanted from kewesoke (white) and western yellow varieties of maize, were used. This study seeks to determine whether water-extract from fermented ground maize (WEFGM) can be a better alternative to water for the production of WBEC, on account of the additives. Water is first deionized to remove corrosion factors (CF) before the additives are introduced. Existing water-based engine coolants (WBEC) are produced by adding corrosion inhibitors (CI) and anti-freezing agents (AFA) to de-ionized water.
