How Often Should I Change Engine Coolant?

CARS.COM — When is the correct time to change your engine coolant? For some vehicles, you're advised to change the coolant every 30,000 miles. For others, changing it isn't even on the maintenance schedule.
For example, Hyundai says the coolant in the engine (what many refer to as "antifreeze") in most of its models should be replaced after the first threescore,000 miles, then every xxx,000 miles afterward that. The interval is every xxx,000 miles on some Mercedes-Benz models with some engines, just on others information technology's 120,000 miles or 12 years. On still other Mercedes, it'southward 150,000 miles or 15 years.

Some manufacturers recommend yous bleed and flush the engine'southward cooling system and change the coolant more often on vehicles subjected to "severe service," such as frequent towing, which can generate more oestrus. The schedule for many Chevrolets, though, is a change at 150,000 miles regardless of how the vehicle is driven.
Many service shops, though — including some at dealerships that sell cars with "lifetime" coolant — say you should exercise a coolant change more than oft than the maintenance schedule recommends, such as every 30,000 or 50,000 miles.
Hither'southward why: Most vehicles use long-life engine coolant (usually a 50/50 mixture of antifreeze and water) in the radiator that for several years will provide protection against boiling in hot weather and freezing in cold temperatures, with little or no maintenance. Modern vehicles also have longer intervals between fluid changes of all types partly because environmental regulators have pressured automakers to reduce the amount of old coolant, besides every bit other waste fluids, that must be disposed of or recycled.
Coolant can deteriorate over time and should exist tested to run across if information technology's all the same practiced, as it can be hard to tell but past appearances. Even if the coolant reservoir shows sufficient coolant level and testing shows the cooling and antifreeze protection are however adequate, a coolant drain and antifreeze flush may be needed.
The coolant can go more than acidic over fourth dimension and lose its rust-inhibiting backdrop, causing corrosion. Corrosion can harm the radiator, water pump, thermostat, radiator cap, hoses and other parts of the cooling system, as well every bit to the vehicle heater arrangement. And that tin crusade a car engine to overheat.
Thus, the coolant in any vehicle with more than than about 50,000 miles should exist tested periodically. That's to await for signs of rust, leaks and to make certain it has sufficient cooling and overheating protection, even if the cooling system seems to be working properly and the reservoir is full. The cooling system can exist checked with test strips that measure acidity, and with a hydrometer that measures freezing and humid protection.
If the corrosion inhibitors have deteriorated, the antifreeze coolant should be changed. The cooling system might also need flushing to remove contaminants no matter what the maintenance schedule calls for or how many miles are on the odometer. On the other hand, if testing shows the coolant is even so doing its chore protecting from overheating and not allowing corrosion, changing it more oft than what the manufacturer recommends could be a waste of coin.
