How much is the reduction of antifreeze in a year?Coolant drops below the minimum line in one year

Under normal circumstances, it is normal for the antifreeze to decrease by about 10%-36% a year. If the coolant drops below the minimum line in one year, most of it is abnormal. Unless vehicles are used frequently, the coolant consumption will be relatively faster.

If there is abnormal coolant consumption, check the conditions of each part, remove the fault point, and repair it in time. First check whether there is water leakage from the outside of the cooling system, and use the tightening method to remove the leaking parts. A dry and clean wooden strip can be used to extend into the drain hole of the water pump for inspection. If there is water on the wooden strip, it means that the pump is leaking.

After the external inspection of the cooling system, if there is no leakage, it can be considered that there is water leakage inside the cooling system. If the engine is running, the exhaust pipe will emit a large amount of water vapor, or when the oil dipstick is pulled outdiscoverThe presence of coolant in the oil can indicate that the water jacket is broken or the cylinder head gasket water passage hole is damaged, which causes the coolant to leak into the crankcase, the cylinder, or the intake and exhaust pipes.

If you find that the coolant is not normally consumed, you should go to the repair shop for inspection in time to avoid damage to the engine and its operation due to the lack of coolant. Coolant is to ensure that the engine can work within the normal temperature range, plays an important role, can well protect the engine.
