Coolant is a liquid or a gas form available in multiple colors, generally in light yellow or green color, is used to remove or reduce heating effect from something. However here we are specifically talking about a coolant that is used to remove heat from engines, especially in automobiles like cars, trucks, etc. It could also be used in heavy machinery where engines produce heat and the purpose of coolant is to regulate and control the temperature of the engine. it is in fact a combination of water and oil chemical which also avoids rust.
Here is the complete package with test methods and parameters used to analyze capability and effectiveness of coolant.| COOLANT FLUID ANALYSIS PARAMETERS AND TEST METHODS | |
