The most common cause of corrosion in your radiator system is sludge, a black, mud-like substance which, if untreate will build up over time. From the inside of your radiators , it will cause rusting which end up eating tiny holes in the radiator resulting in leaks.

Leaks around hose connections can also cause antifreeze to ooze out of the car. As a car owner, wouldn’t it be impractical for you to think that you will never have to deal with a radiator leak ? This common issue has several causes and a number of signs as well. One of the causes is when the tubes carrying the coolant to or from the engine get raptured.

Another major cause of radiator leaks is over-pressurization.

This occurs when the thermostat sticks, or a head gasket fails. Most radiator leaks are found at a joint that is between the radiators tank and core. Leaks in the radiator itself are harder to locate and repair than problems with hoses.

Look for bubbles or steam coming from the radiator to signal the location of a leak. The main reason for radiator failure is a leak , which can lead to the cooling system failing. If the coolant has not been checked or topped up properly the inside of the system will begin to rust and become clogged.
