Engine coolant are often referred to as anti-freeze. This is because the original coolants were mostly water and they had to figure out how to keep them from freezing in the winter. So, what’s in coolant/anti-freeze:
- Glycol – 50%
- Water – 46%
- Corrosion Inhibitors – 4%
While glycol and water levels will stay pretty consistent, corrosion inhibitors can deplete and, in the past, had to be replaced with SCA’s (Supplemental Coolant Additives). Maintaining the correct levels can be tricky and if not done properly can lead to engine damage. Technology advancements gave us extended life coolants with (NOAT) Nitrited Organic Acid Technology to reduce the need for SCA’s and provide better engine protection. NOAT’s have issues with some aluminum components and this drove the industry to develop non-nitrite alternatives.
Engine coolants have gone through several changes in the last few years. Whether it’s the color, SCA’s, NOAT or OEM recommendation, it’s hard to keep track of what you should use. Considering that 40% of all engine downtime is coolant related, isn’t it time to figure this out. Check out the video from Mobil to help get a better handle on coolant.
