* Antifreeze is a separate system: The antifreeze (coolant) circulates in a closed loop called the cooling system, separate from the engine's temperature gauge.
* You check the antifreeze level: You check the antifreeze level in the coolant reservoir or radiator (when the engine is cold). The color of the antifreeze can also tell you if it needs to be replaced.
Here's what you *do* need to consider:
* Safety: Always allow the engine to cool completely before opening the radiator cap. Hot coolant can cause severe burns.
* Full level: Make sure the coolant level is between the "full" and "low" marks on the reservoir.
* Color and clarity: Check the color of the coolant. It should be the color it was originally (typically green, orange, or pink). If it's discolored, rusty, or cloudy, it might be time to flush and refill the system.
When to check your antifreeze:
* Regularly: Check your antifreeze level at least once a month, or more often if you notice any leaks.
* After maintenance: After any maintenance involving the cooling system (like a hose replacement or thermostat change), check the coolant level.
* If you suspect a leak: If you notice any leaks or smell coolant, check the level immediately.
Important note: If you're unsure about anything, consult your car's owner manual or a qualified mechanic.
