What You Need to Know About Honda Civic Coolant

Coolant engine generic being added

Your vehicle’s coolant or antifreeze is essential to your performance around Carmel. Used to regulate the temperature of your engine, liquid coolants are composed of half water, which is used to transfer heat, and half ethylene glycol, which is used to lower the bleak point of the liquid.

While you can purchase full-strength antifreeze, it’s the mixture of antifreeze and water that creates a conducive coolant for your engine. With Penske Honda, learn about your Honda Civic antifreeze and what Honda coolant color you should look for when performing DIY care. If you have any questions, contact the technicians in our service center

Honda Coolant Color

While you’re likely to see yellow, red, or green coolant colors when shopping around Fishers, it’s important to understand that coolant color doesn’t matter as much but can be different across manufacturers. You’ll find that most Organic Acid Technology (OAT) coolants can be found in orange, yellow, red, or purple, while Hybrid Organic Acid Technology (HOAT) coolants are orange and yellow. However, you also have Inorganic Acid Technology (IAT) coolants that are usually green, or sometimes blue. 

Your best bet in identifying the right Honda coolant color for your model is by checking your vehicle’s owner’s manual and paying attention to the details on the coolant bottle. If you’re looking to take care of your vehicle’s coolant levels at home, reach out to our parts center to find the right tools for your model. 

How Long Does Honda Civic Coolant Last? 

With the various types of coolant, how long your Honda Civic antifreeze lasts depends on what type was used. Up until the mid-1990s, there was a single green coolant formula that contained corrosion inhibitors that lasted around 24,000 – 36,000 miles, or two to three years. Newer formulas using Organic Acid Technology can last twice as long. There are even long-life coolant options that can last 5 years, or 100,000 miles. 

In general, it’s recommended that you have your Honda Civic coolant checked every 15,000 miles, and flushed around every 30,000 miles, or every two years, to make sure no debris or sediment are harming the engine.

When Is It Time for a Honda Civic Coolant Flush?

When you’re Westfield trips aren’t as smooth, keep an eye out for these common signs that your Honda needs a coolant flush: 

  • You may notice steam from underneath the hood or coming from the radiator
  • The check engine light will illuminate
  • Unusual grinding noises can be heard from the engine
  • A visual check of the coolant shows sediment or rust 
  • While less likely, you may smell a burning odor coming from under the hood
  • After starting the engine, the temperature gauge will read well above the normal range
  • Your heater may stop working
  • Check underneath your car, coolant may be leaking when the engine is running
