A radiator is a heat exchanger that your car cannot do without. There are some signs that can tell you if your radiator needs replacement. One major sign that you have a problem with your cooling system is leaking antifreeze. You may also smell antifreeze while you are driving if you have a coolant leak. If coolant is leaking, causing the antifreeze level to drop, a low coolant light may be lit on your dashboard to alert you that there is a problem. In general, if you have noticed that the vehicle is overheating, there is definitely a problem with your radiator or cooling system. Pay attention to the thermostat in your car! Occasionally thermostats can get stuck, causing your engine to overheat. Radiators can also crack or start to leak over time as well. Radiator caps can also break or crack, causing leaks. Hoses can get soft and develop leaks over time, causing your vehicle to lose vital antifreeze. You don't want a problem with your cooling system to cause major issues that could have been avoided.
