Radiator problems may start gradually or quickly, depending upon the nature of the issue. Your car’s radiator is one of the most important components of the engine and is responsible for keeping the motor and other parts of the car at a moderate working temperature. While prevention is the best when it comes to radiator problems, it equally pays also to recognize the first signs of radiator trouble. This will allow you to solve any problems before they become severe and potentially hazardous.
The first sign toward a radiator problem is your engine temperature gauge. If you notice the engine operating at a high temperature than normal, and particularly if you notice a sudden spike in the working temperature, this may be a sign of impending radiator problems.
If you suspect any radiator issues, examine the radiator and engine while the car is cool. Never touch a radiator or engine while the engine is running, as the components will be very hot. If you notice any leaking around the radiator or the cooling system, this is another early sign of radiator trouble.
Lastly, if you notice any smoke or steam coming from your engine or any other part of your vehicle, this is a sign of imminent radiator problems. In any of these cases, consult with a mechanic for help.
