But if you added additional antifreeze concentrate to your system last winter, you likely upset the balance of antifreeze / coolant in your engine. Most leading technologies will work very well when used as intended, typically at 50% in good quality water. PG differs from EG in both acute and chronic toxicity. Volvo ELC’s advanced carboxylate technology guards the engine by specifically targeting corrosive … In a modern car with a well-maintained cooling system, current North American and OEM factory fill coolant corrosion protection can be extended far beyond previous expectations. As a precaution, both GM and Caterpillar instruct that contaminated systems must be maintained as if they contained only conventional coolant.

It is usually green or red. Their main concerns with phosphates are the potential for solids drop out when mixed with hard water. With over 40 percent of truck downtime being related to cooling system failure, it just doesn't pay to run cheap engine system coolant. Best Aftermarket AC Systems, Kits, Units. Warning symbol name: Coolant Level Urgency: Medium Description: The VOLVO Trucks coolant level indicator light comes on if the coolant level is low. At what mix is there too little of either inhibitor to protect the engine? It is not recommended to use Dexcool® in a vehicle that did not come from the factory with Dexcool® in the cooling system. So the problem is widespread.”, Dilley says coolant suppliers, including Prestone, responded to this problem with a host of new products, including new test strips to confirm and correct coolant blends, and new coolants that will simplfy that process. ... both GM and Caterpillar instruct that contaminated systems must be maintained as if they contained only conventional coolant. It is recommended for use in Toyota/Scion/Lexus and other automotive and light duty vehicles requiring a OAT engine coolant. The phosphate level in most US and Japanese antifreeze formulas do not generate significant solids. You’re far from alone. Heavy-duty engine coolant suppliers realize they have a problem on their hands today with multiple-colored coolants on the market — a situation further exacerbated by two different red-colored coolants with very different performance properties. “The problem, of course, is for mixed fleets. Advertisement. “Most fleet managers today do not know exactly what is in their engine cooling systems,” Dilley says.

Compared to old-fashioned phosphate antifreeze, Dexcool® may be more stable and improve water pump life. If levels drop below this the protection of the cylinder liners is compromised. So you end up with a fluid that is now causing corrosion inside the engine while offering severely reduced protection.”, The main culprit in this process is the liquid ammonia, Granger confirms. “That’s not the case, now.

Extended coolant life—to 1,200,000 miles or 24,000 hours of operation 1 —reducing maintenance costs and downtime. The benefits provided by the phosphate include: European manufacturers feel that these benefits are achievable with inhibitors other than phosphate. It can be used in any engine requiring a OAT engine coolant. Sometimes greater concentrations of nitrite can cause the O-ri… Blue coolant is usually an Organic Acid Technology base and what makes it different from red coolant is that they’re normally Borate free which is a requirement for modern day Japanese vehicles that are supplied with blue coolant from factory. However, if the concentration of nitrite is greater than 800 ppm, other things are compromised. Both ethylene glycol (EG) and propylene glycol (PG) are used as the antifreeze base. Adding radiator coolant or topping up coolant (or radiator fluid) as many call it, is very important to the proper cooling of your vehicle. So here are three industry trends in coolant, and what fleets need to know about them. Repairs are costly and create unnecessary downtime that affects equipment operations and customer deadlines.
