Antifreeze and engine coolant are the same product, sold in the same packaging, and both go into the vehicle's radiator. All gasoline engines need water to circulate through them to maintain a stable operating temperature. Antifreeze keeps the water stable across a broad range of temperatures, from


The colors of antifreeze coolant are green, red, blue, yellow or pink. The color of antifreeze coolants varies depending on the manufacturer. Each color signifies a purpose in vehicle maintenance.


Antifreeze is used to lower a freezing point, whereas coolant is used to remove heat. Antifreeze is chiefly used to lower the freezing point in the radiator of a motor vehicle. Coolant is a substance typically used to reduce the temperature of the liquid in an automobile cooling system.


Antifreeze and coolant are essentially the same thing. The Automobile Association (U.K.) uses the terms interchangeably or together (coolant/antifreeze). Antifreeze is colloquial for the chemical fluid ethylene glycol. Ethylene glycol and distilled water, in equal proportions, are added to radiators


A chart explaining the different colors of antifreeze and the year and models in which they are used is available on Carid.com. The Whitfield Oil Company also has a similar chart produced by Zerex on its website.


Replacing a vehicle's antifreeze involves draining the old fluid using the drain valve at the bottom of the radiator and replacing it with new antifreeze. The antifreeze mixture should be 50 percent coolant and 50 percent water.


The different types of antifreeze include ethylene glycol and propylene glycol, which are prominently used as car engine coolants. Less popular antifreeze agents are methanol and 1, 3 propandiol and glycerol.


Most antifreeze is made from ethylene glycol, but it can contain other chemicals or ingredients, such as propylene glycol, ethanol, methanol and isopropyl alcohol. Some modern types of antifreeze include chemicals that allow them to last twice as long as conventional fluids, while other antifreeze t


Test the antifreeze in an automobile using an antifreeze tester. This device includes a squeeze bulb to pull antifreeze from the radiator, a cylinder with floating balls, and a tub to reach into the radiator. The number of balls floating in the liquid indicates the concentration of antifreeze in the


Replace the plastic coolant tank on a car by waiting until it is cool and releasing the pressure slowly if it is pressurized. Disconnect any hoses leading to the radiator and remove the old unit. Attach the new unit to the mounting bracket and clamp the hoses in place. Refill the unit with coolant a
