How Often Should I Change my Engine Coolant?

Most vehicles come with long lasting engine coolant (that usually consists of a mixture of antifreeze and water on a 50/50 scale) that will provide protection against boiling or freezing temperature with little or no maintenance. For most vehicles, the producer advises that coolant should be changed at 30,000 miles. Some others, changing of coolant can’t be found on the instruction schedule for maintenance.

Hyundai has told us that the coolant (mostly referred to as antifreeze) in a variety of its brands should be checked after 60,000 miles of the first use, then consequently at each 30,000 miles after. Meanwhile, on some Mercedes-Benz models, the time frame is on 30,000 miles and12 years or120,000 on others. And still, on other Mercedes, it could be every 100,000 miles or 10years.

Change Engine Coolant

Ford engineers advice to replace within the first 100,000 miles and subsequently at every 50,000 miles. Although vehicles that apply heavy-duty activities (like constant towing) should replace more regular than required. No matter how straight the maintenance schedule is for your vehicle type, after a couple of years of ownership, it’s undoubtedly a better idea to get the coolant periodically checked out for rust, acid buildup and other known contaminants, and also to resist freezing and boiling, add water.

To top off the cooling system, if you have added water (tap water in particular), you will reduce significantly some contaminant. Dilute the antifreeze/water mix (generally 50/50) and by doing so alter their freezing and boiling points.

Benefits of Coolant

  • Better performance
  • Better temperature flow
  • Clean engine

Modern vehicles naturally have longer time bound between changing fluids, but sometimes what you see on the surface can be deceiving, and since Coolants deteriorate over a period, it is advisable that it be should be tested just to know if it’s still good. Reasons being that some antifreeze tends to become very acidic with time its rust-inhibiting attributes may be gone, unavoidably causing corrosion.

What Type of Coolant is Best?

Although most manufacturers recommend changing of coolant more regularly on vehicles

prone or more likely to engage in severe workload such as frequent towing, like Chevrolet, the schedule of certain Chevrolet brand though is to change it at approximately 150,000 miles

regardless of how the vehicle is used. Most Manufacturers specifically recommend some particular types of coolant. Some may be green, or red, they may vary in color, but the idea is to not go to a parts store just to get the best color. Getting the right type of coolant for your vehicle. It doesn’t matter if you’re doing it yourself or having it done for you by a professional.

Otherwise, if the test carried out shows that the coolant is functioning at its best and not giving yield to corrosion to take place, changing it more frequent than recommended by the manufacturer could end up as a total waste of resources.
