Semi truck red coolant8/3/2023 The green antifreeze contains silicates, phosphates and / or borates as corrosion inhibitors to keep the solution alkaline. This type is good for two to three years and up to 30,000 miles. Most antifreeze products sold for the past several years have been the traditional "green" coolant. Never use pure antifreeze in a cooling system without using at least 30 percent water in the mixture. This gives freeze protection down to minus 34 degrees and boil-over protection up to +265 degrees. Antifreeze should be mixed with distilled water (tap water contains high amounts of minerals such as calcium and iron that can precipitate and coat internal parts) at the ratio of one part antifreeze to one part water. Most of the antifreeze products on the market currently are ethylene glycol base material with additives to prevent corrosion, lubricate seals and water pumps and aid in heat transfer to the coolant from the metal of the engine. If you own water-cooled equipment such as cars, pickups, trucks, tractors and combines, it * s time to check the freeze level of the coolant in the radiator and cooling system or replace with new coolant mixture if the mixture has not been changed according to your maintenance schedule. They do however recommend multiple brands of green and red types of antifreeze.Cold weather is approaching. You might also note Cummins, Cat and Detroit do not recommend orange antifreeze at all. Currently, orange has been made safe for all radiator types. It was death to copper radiators, and that's where half the confusion lies. Orange antifreeze (Dex-Cool) has historically been used by GM in aluminum radiators only. Where as the Ford, Chevy and Dodge Antifreeze isnt nearly as backwards compatible with Cat, Cummins and Detroit engines. One thing I did notice is pretty much all the Heavy Engine Manufactures Coolant's will work in the next engine. While reading through the Coolant Matrix chart, and everything becoming clear as mud. Footnote 13 contains a link "Coolant Matrix" Scroll to the footnotes at the very bottom. I found a pretty good link from WIKI on this subject. You regularly use test strips to monitor conditions of your cooling system, and use pre-charged coolant cartridges as required. Water only will ALWAYS lead to catastrophic engine failure if operated for an extended period.ģ. Any color antifreeze is ALWAYS going to be a much better bet than letting it go dry or filling with water. For a non healthy engine, any antifreeze will do as youll probably be draining, flushing and replacing the entire volume ASAP. In that case you are headed to a heavy truck dealer for parts or a repair shop that "knows" what coolant is compatible with your heavy truck engine. Topping off is only necessary once or twice a year, and it would not affect SCA or other additives in a negative way.Ģ. If not, the coolant system is not healthy and should be serviced. A radiator should never need refilled unless done intentional as an act of regular service maintenance. Topping off is not the same as refilling. I would revise that and say it would be safer (in a pinch) to top off "any color antifreeze" with green.ġa. In that case as stated in the Matrix (see link below) its ok to top off with any color as long as you dont go over 10% of total volume. Your engine is in good shape, and your just topping off the coolant system. Click to expand.In regards to my first post, it was assuming a few things:ġ.
