It did yesterday when I got home from a pretty hard ride, not sure if it had been boiling over the whole time or just when I got home and let it idle for a second while I opened my gate. Make specific there is no oxygen using the lines by examining the oxygen bleed valve below the oxygen box. When you replace the flushed system with new coolant it just gets mixed with the old stuff left over. not sure but after reading on Purple Ice it seems to reduce the boiling point of Water, which lowers the air bubbles, causing more cooling/contact ratio. I was lucky that one of the two cars was still in warranty so that one did not cost me but the other one did cost me for a new pump and timing belt.

Before adding coolant your cooling system must be clean and have no chemicals of any kind left in the coolant loop. When you shut the engine off it will cool down and the expelled coolant will be drawn back into the coolant system. This recommendation is based upon the high-performance characteristics of Engine Ice and is accurate for all types of vehicles. I added just enough to the overflow reservoir to bring the level from just below the low mark, to the full mark.To parrot what others have said, you should be concerned about that -7F freezing point more than it gelling on you, especially if you topped it off with the same color antifreeze. I was just checking to see how accurate the statement of "does Not have antifreeze characteristics" was. Your cooling system is the mechanism to maintain that optimal temperature allowing all the engine components to maintain a long life. Granville Rapid Cool Blue Antifreeze and Coolant is a Monoethylene Glycol based antifreeze that does not contain nitrates,amines or phosphates. This exposes hot engine components to air and vapors, causing corrosion and contamination of the coolant with iron oxide particles, which in turn can aggravate the pressure cap problem as contamination holds the caps open permanently.

I ran the motor for about 15-20 mins while purging but feared to leave it more time after nothing else came out and risk overheating or something. If you live in an area that encounters freezing temperatures, you could be aware of pipes splitting inside your home. I feel that KTM is trying to direct folks to Motorex instead of helping consumers find affordable quality products that can easily be purchased.I looked up "NAP Free" and it means "NO NITRITE, NO AMINE, NO PHOSPHATE, and NO SILICATE", therefore Zerex G-48 is still an option. Due to X1 being a reformulated vegetable extract the colour of the coolant can vary from clear to straw yellow in colour. If you actually read my post I did not just say redline I also mentioned blue ice which does the same thing. In short, yes, it is highly recommended that anytime you change your coolant, you should flush the system. My personal advice if you were planning on using beer as substitute coolant is you should certainly drink it first.

I posted a small tidbit about a product that has proven itself to me, and mentioned it helped with a couple items. GM (Motors Liquidation Company) filed for bankruptcy in 2009, which tied up the outstanding claims until a court determines who gets paid.Flushing the system as directed is the best way to ensure your new coolant performs at its best and provides dependable results for best results, flush with Engine Ice Flush Treatment or an equivalent product. Mayhems UV Clear Blue appears clear under normal lighting but turns ice white with a subtle ice-blue aura/haze under ultraviolet lighting. This just may be the most unbelievable product you have ever used; Engine Ice Hi-Performance Coolant is here!

Its not magic or snake oil, its simple chemistry that's used in all kinds of other applications, similar additives are used in office building HVAC water based cooling systems for example, for increasing pumping efficiency in pipelines etc.All the ingredients of X1 are generally recognized as safe (GRAS) by the US FDA so there is no need to worry about the safety of the product in your home. IIRC, I used less than a gallon, and that includes spillage from the burping, so that sounds about right.
