[QUOTE="astroboy, post: 415263, member: 4527"] Okay! Back to Automotive Coolant 101.. :D :D [U][B][COLOR="Blue"]http://en.wikipedia.org/wiki/Coolant[/COLOR][/B][/U] Fact 1: [U]Coolant[/U] is just a [U]heat transfer medium[/U] in general and can be in [U]either gas or liquid form[/U]. When in liquid form, the most common is [B]WATER[/B].. :D :D Fact 2: Liquid coolant (water :D) is usually used with [U]additives[/U], like [U]corrosion inhibitors[/U] and antifreezes. Antifreeze, a solution of a suitable organic chemical (most often ethylene glycol, diethylene glycol, or propylene glycol) in water, is used when the water-based coolant has to withstand temperatures below 0 °C (not applicable here :D), or when its boiling point has to be raised above 100 deg Celsius. If u only use water as coolant, can! But, 1. your boiling point is limited to 100 deg Celsius (H2O boiling point). What is boiling point? Boiling point is when an object evaporates. So your water coolant level drop very fast compare to another car that use "coolant" (with additives) as coolant (higher boiling point). 2. Anti corrosion/rust additive is often used. So if you use pure water, your cooling system will suffer corrosion or rust issue. 3. Lubrication additive is also used to lubricate your water pump. So using pure water, your water pump won't last as long as another car that uses "coolant" as coolant. 4. The above mentioned additives wear out through time and therefore, you will still end up with H2O through time. Therefore, periodic replacement is necessary to benefit from fresh additives. Did I confuse u? :D [/QUOTE]
