A radiator is an important component of the vehicle’s cooling system. Its main job is to keep the car cool. However, like other mechanical and electrical components, it can develop issues that make the engine of the speed machine problematic. Leaky hoses, faulty thermostat, cracked radiator, failed water pump and radiator fan- are some of the things associated with a faulty radiator. If you suspect the radiator is faulty, then the first thing that you have to do is to take your car to a professional car-geek for a full diagnosis. Because only a versed mechanic can tell what he needs to do to put it right.
