1What Coolant Does
Coolant (antifreeze) circulates through your engine, absorbing heat and transferring it to the radiator. It also prevents freezing in winter and protects against corrosion year-round.
2Checking Coolant Level
Look at the translucent reservoir under the hood. Coolant should be between MIN and MAX lines. Check when the engine is COLD to avoid burns.
Pro Tip: NEVER open the radiator cap when the engine is hot. Pressurized steam can cause severe burns.
3Coolant Colors
Different manufacturers use different colors (green, orange, pink, blue). Never mix colors unless you know they're compatible. Stick to what your vehicle uses.
4When to Replace
Most coolant should be flushed every 5 years or 100,000 km. Check your owner's manual for your specific interval.
