If your car’s radiator is ready to be replaced or needs repairs, try doing it yourself. Most people think the radiator is one of the toughest DIY jobs for an automobile, but two factors make it easier than you may think. For one, the radiator’s connections aren’t too complicated. The component is secured at all four corners and possibly a bracket or two, usually by bolts (sometimes by screws). Plus, there are a few hose connections. And secondly, the radiator is one of the most easily accessible parts in most cars – it’s usually at the front of the engine, with plenty of room to maneuver.
