![]() ![]() Consult your owner’s manual to determine the actual service interval for your vehicle. Some general guidelines are listed below. ![]() These coolants are different in their components, stability, technology and improvement. It helps to distinguish the different types of coolants available better. To this end, various antifreezes have been formulated to try to combat these problems with different aims and different levels of success. Different types of engine coolant require changing at varying intervals. What Is the Difference Between Red and Green Coolant Coolant comes in different colors, and there is a reason for that. Namely, it freezes in low temperatures, boils at a relatively low temperature, and often speeds rust & corrosion in mechanical parts. Premium Antifreeze Green Radiator Coolant- 3 Liter Mix Ratio 1:3 Coolant for Petrol, Diesel and CNG Vehicles Generator & Heavy Duty Vehicles Coolant. Now, water’s great at taking on heat and giving heat off, but it also has some undesirable properties when it comes to cooling mechanics. You’ll often hear of high-tech things being “liquid cooled” – which sounds super fancy but is actually just a case of pumping water-based coolant through pipes in order to warm the water up and take that heat away from the thing you want to cool. They should really be called “engine regulant” or something official-sounding like that because their job is twofold: to stop engines getting too hot in the summer, and to stop them getting too cold in the winter. The new coolants DexCool (GM), Toyota Long Life, G-05 (Europe and now ford and Chrysler) etc are an attempt to get away from corrosion inhibitors with short lives so that change intervals can be increased.While they often go by different names, antifreeze and engine coolant are the same thing. The Japanese used to use phosphates and no silicates, the Europeans used to use Red coolant typically has a base of Organic Acid Technology which is designed to be more suitable for aluminium radiators. The Europeans do not like phosphate, supposedly most of Europe has hard water, if used with distilled water and changed out regularly should not be a problem What colour do you need Green coolant is the conventional coolant (Ethylene Glycol base) and is the most popularly used coolant. Car owners have been thinking a lot about this question because there can be two answers. Phosphate is also effective especially on steel/iron but can have problems if the coolant becomes acid over time or if water is used that has minerals. You can mix pink and green antifreeze however, there might be some harmful effects in mixing two different coolant colors, so you might want to think twice before mixing a pink antifreeze with a green antifreeze. The Japanese don’t like it, changed regularly is should not be a problem. If not changed regularly it can settle out as a gel or even a solid and abrade the water pump seal. ![]() Silicate is an effective corrosion inhibitor especially for aluminum. Neither should cause problems if used correctly and changed out regularly. )Ĭlassic American coolants contain both phosphate and silicate as corrosion inhibitors. (I probably just jinxed myself with the above post. You don't want to be the next to post about white smoke from the tailpipe. Now would be a good time to freshen up that cooling system. (Clogged radiator, busted belt, failure of PHH, bad thermostat, faulty radiator cap, and bad fan clutch ) Nobody is 100% certain of the cause but, IMHO, the failed head gaskets are frequently a result of overheating caused by another cooling system problem. ![]() There are a lot of other things you should do to keep the cooling system in top shape but these are the critical things.Įvery Spring & Summer for the past 4 or 5 years we have a rash of reports of over-heating and failed head gaskets. Refill using DISTILLED water and the proper mixture of coolant. Use a quality coolant (Toyo Red, Prestone, Zerex ?) Do not use Dexcool.ģ. Most conventional green or blue coolants use an inorganic (IAT) technology to prevent corrosion, that is, they are ethylene glycol or propylene glycol based. (Repeating from Robbie's post, Raven's post, Rich, et. Those lurkers and newbies reading this thread should take note that those of us that have been following the maintenance on the US 80 Series over the past 4 or 5 years will recommend several things to keep the cooling system in top condition. ![]()
