The pre-diluted stuff is more convenient of course, but you end up paying a lot more for less coolant. 10 Best Engine Antifreeze & Coolants (2023 Guide) 10 Best Engine Coolants & Antifreeze of 2023 Find out how to choose the best engine coolant and antifreeze for your car based on factors such as quality, price, performance, warranty and more. Years ago coolant was always sold as pure coolant, and you'd have to dilute the fluid yourself with water. One thing to keep in mind with nearly every modern jug of coolant you’ll come across: They’re all pre-diluted. All GM cars use something called Dex-Cool from the factory. Plenty of others like BMW and Volkswagen do the same thing. Many times, the coolant is actually branded for the car you’re going to put it in.įor example, Honda sells its Type 2 Antifreeze/Coolant in all its dealers. They’ll sell the coolant for your specific make and model, and it’s guaranteed to be the correct one. The easiest way to make sure you’re getting the right coolant for the job is to go to your car’s dealership. Finally, HOAT is a derivation of OAT that requires the same time change interval unless otherwise specified. General Motors vehicles use this formula and normally require a change after five years or 50,000 miles. It needs to be changed every two years or 24,000 miles, making it far inferior to newer formulas. ![]() You want to check the antifreeze or coolant level while. When filled, the coolant/water mix should reach the “max” line on the reservoir if your vehicle has one.Play icon The triangle icon that indicates to play Ideally, you should do so after driving the car a short distance. ![]() As mentioned earlier, a coolant is water and ethylene glycol, usually. If you spot leaks elsewhere, you will likely need to take your vehicle in for professional repairs. The majority of cars use a liquid cooling system that circulates a liquid around hot engine parts and carries off heat. Mixing water and coolant causes the engine to overheat because it dilutes the coolant. If the drain valve is leaking, tighten it to stop the leak, as it will get worse under pressure. So if the coolant for car already has this in the right amount, nothing will happen if you don’t mix water with coolant. Check below the car for any leaks, particularly near the drain valve.Make sure to pour in the amount of coolant/water mixture your owner’s manual indicates is correct for your vehicle’s engine.Thus, your engine can operate just fine in temperatures well. Likewise, it also raises the boiling-point elevation. Prestone Antifreeze+Coolant keeps the water pump looking like new after. When properly utilized, the solution lowers the freezing point of a water-based liquid. The water pump keeps fluid circulating through the critical parts of your engine. Some systems require you to pour the fluid in slowly, as it gradually displaces the fluid out of the reservoir and into the coolant lines, so be patient to avoid overflowing. Today’s formula for antifreeze will keep cars from overheating, and this is why it has become interchangeable with the term coolant. ![]() Pour the coolant into the same open cap you previously used to fill the radiator with water. Most vehicles require a 50/50 mixture of coolant and water, so you can either mix it yourself or purchase pre-mixed coolant and water from your local retailer. Refer to your vehicle’s owner’s manual to ensure you fill the vehicle with the correct coolant. ![]()
