I didn't see any mention on eBay (have not looked closely yet) of the flush. They have another version for large diesel truck engines, and a third exclusively for race cars that are not street driven, and a fourth for motorcycles/ATV's (power sports vehicles). For anyone else who wants to get into this product for their Fit, the "NPG+C" is the formula for daily drivers. But I do intend to continue investigating, and I will probably proceed with an expensive purchase and go ahead with the flush & fill with the magic coolant.Ī little cheaperI always check eBay and Amazon before I buy anything direct, but thanks for other people who might have paid the direct price. I am in no hurry to spend that much money at the moment. So to make this effort effective for the future, I need to have extra coolant to make up for any leaks that might possibly come up, as well as the additional gallon of flush formula. So they sell a special "preparation flush formula" that supposedly combines with water and removes it as the flush is drained. In trying to completely exchange the water-based coolant for the new waterless stuff, remaining water will reduce the effectiveness of the new coolant, and will still cause corrosion. It is nearly impossible to completely drain all coolant from an engine block and all hoses, radiator, heater core, etc. So I will need to pay UPS shipping charges for several gallons of stuff weighing 8 pounds per gallon. It turns out that the Evans dealer near me only sells the motorcycle formula of the coolant. The Evans coolant sounds like it answers absolutely all coolant issues for engines and helps the environment too. ![]() The non-toxic coolants sold by Peak and Amsoil is Propylene Glycol. The poison will be neutralized and you will survive. ![]() Not totally successful in either case.īTW- if you somehow get poisoned by drinking Ethylene Glycol and get to a hospital before kidney and liver failure set it, the antidote that you will get is a big glassful of Propylene Glycol to drink. in engines with trying to limit corrosion. Ethylene Glycol and/or Propylene Glycol have always been a compromise- the best they could do to balance raising water boiling temps. on which of their formulas is the best for a Fit, and intend to buy this stuff. Thanks! GREAT find! I will visit the Evans web site to get more info. Jay Leno's Garage: Waterless Engine Coolant - YouTube In the fit it would only cost $50 for this stuff and if it last the life of the engine without corroding your engine, water pump, hoses, and radiator I think thats money well spent. Put another way, if your engine puts out enough heat to warm your 50/50 coolant by 10C, it would warm pure PG by 13.5C.Has anyone even heard of this stuff? Honda requires that you change your coolant every 3 years. So, to oversimplify a little bit, if your 10-quart cooling system moves some amount of heat at a specific temperature, you'd need a 13.6 quart PG system or an 8-quart pure H2O system. Straight PG is 0.59, and the usual 50/50 EG/H2O mix is around 0.8. The specific heat of water (in cal/g or kcal/kg) is 1.0. I ran my QSW on about 95% water, 5% glycol (for corrosion resistance) one summer. as much water as you can run without running the risk of freezing) will cause it to run cooler. In a system with a HUGE radiator (say, a GM), it's probably not such a bad idea, but in systems that are a little small, MORE specific heat (e.g. If higher boiling point alone were a good thing, I would put biodiesel (soybean oil ester) in my cooling system-its boiling point is over 200C With a 20psi cap on, you could be well over 200C before you boiled the coolant. Since PG doesn't boil until 188C, you can get your engine all the way up to 188C with zero pressure-not exactly a good thing in an engine designed to run in the mid-90s. In order to move as much heat, you have to heat the PG to a higher temperature to get that heat away from the engine, causing your engine to run hotter. While it is true that 100% PG will run no pressure and cause less stress on your hoses, it simply cannot move heat away from your engine as quickly as water or EG/water mix can. ![]() Keep in mind that your radiator doesn't get rid of temperature (degrees), it has to get rid of heat energy (calories, joules, Btu, however you want to measure). On a car with a cooling system that's too small for the hot summer already, you're reducing the capacity further by running Evans. The problem is that waterless (100% propylene glycol) coolant has a considerably lower specific heat than water, that is, it takes less heat energy to warm waterless coolant than a 50/50 antifreeze mix (which is less still than straight water).
