How Often Should Car Antifreeze Be Refilled?

[HopeMarie]

Car antifreeze should be refilled every two years or 40,000 kilometers, whichever comes first. The method for changing antifreeze: 1. Locate the antifreeze reservoir and follow the storage tank to find the lower hose; 2. Find the position of the hose clamp, use clamp pliers to grip the clamp, squeeze the pliers firmly to open the clamp and lock it; 3. Pull the rubber hose forcefully, and the antifreeze will flow out; 4. After the antifreeze has completely drained, you can refill with new antifreeze or clean the system before refilling. The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. It prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. Antifreeze also reduces corrosion in the engine cooling system and has anti-corrosion and rust-removal functions.
