On most vehicles, you can check your coolant level by peeking into the radiator fluid reservoir tank. Wait until your engine is cool, then simply pop the hood of your vehicle, identify the coolant reservoir (usually a small transparent tank with MAX {maximum}/MIN {minimum} or FULL/ADD lines marked on the side), and look for a cap with “engine coolant” or “antifreeze” stamped on the top. Antifreeze is a concentrated product, normally based on glycol and contains inhibitors, according to the AA. Some types have to be diluted with water to make them a suitable concentration before use, which is where the name coolant comes from. Coolant is a 50-50 mix of antifreeze (ethylene glycol) and water. You may have heard the terms antifreeze and coolant used interchangeably at some point, leading you to think they’re the same thing. Well, not exactly. For today’s post, we shed some light on the differences between antifreeze vs coolant. Antifreeze vs. Coolant: How They Differ. Antifreeze and coolant are similar in many respects, and they share the same purpose. However, they are not the same. Typically, antifreeze consists mainly of ethylene glycol, an ingredient that has an extremely low freezing temperature. Step 5: Pour the Coolant into the Reservoir and Radiator. Use a funnel to pour the coolant into the tank. Pour in just enough until it reaches the “Max” line. The same thing goes for the radiator. If your radiator doesn’t have a fill line or you can’t find it, pour the coolant in until you can see it reach the bottom of the filler neck. Coolant is a diluted form of antifreeze. This means they have the same base properties but work best in different climates. Coolant protects your radiator all year long and antifreeze is designed to give it some added protection in the winter. Good quality coolants tend to have antifreeze properties as standard, but it's always worth checking 2PyjV. It removes old coolant, dirt, rust and other deposits. Instead of letting gravity do the work, flushing uses water pressure to blast any accumulated bad stuff out of the cooling system’s passageways. Both the radiator and the engine block are cleaned out. The final step is to add new replacement coolant. Radiator coolant is a necessary component in any engine cooling system. Coolant helps to regulate the temperature of an engine by transferring heat away from critical areas. It also protects the system against freezing and corrosion. There are many different types of radiator coolants on the market, but not all of them are created equal. Antifreeze also lubricates cooling system components which come in contact with water, and keeps metal components from corroding. Are antifreeze and coolant the same thing? The terms "antifreeze" and "coolant" are often used interchangeably, but this is not correct. Antifreeze is one component of an engine's coolant. Not much, actually. Antifreeze, usually ethylene glycol, does not freeze easily. It also does not boil easily. When it is added to water, it becomes coolant. You can buy it separately and add it to the water in your radiator—usually aiming for a 50 percent antifreeze to 50 percent water ratio—or you can buy it premixed, generally in that On most vehicles, you can check your coolant level by peeking into the radiator fluid reservoir tank.

Red and Pink are two different technologies, but are fully compatible. Red is good for 2-3 years/24k-30k miles, and Pink is good for 5y/50k with only the factory fill supposedly good for 10y/100k (when not poisoned with other coolants, or topped off with tap/well waters). When Red&Pink are mixed, use the 'lesser' interval.
