The radiator is an important part of your vehicle. If you start to notice an issue with your vehicle overheating, it may be caused by the radiator. In order to keep the internal engine temperature at a manageable level, coolant fluid flows around the engine block. When the temperature exceeds a certain point, the thermostat opens up, allowing coolant to flow into the radiator through an upper entry tube. A fan helps reduce the temperature of the coolant, and the fluid goes back into the engine through a lower exit tube. There could be some issues that cause your radiator to go out. A rusty radiator will soon overheat, causing major engine issues. If you see a brownish color in the coolant, that means the radiator is rusting from the inside. If enough rust spreads over the radiator, small holes will develop. Those small holes will turn into larger holes. to that extreme pressure buildup, the rubber hoses which connect the radiator to your engine will fail eventually. Plus, the metal hose clamps can also rust or loosen. Whenever hoses start to fail, leaks aren’t far behind. If your car has a sticky, slightly sweet-smelling green fluid on the ground, that’s an indication you’ve sprung a radiator leak. But hoses aren’t the only reason for leaks; radiator body rust is also another common cause of system leaks. A radiator doesn’t just overheat for no reason; underlying issues contribute to this major problem. Regardless, whenever your car’s engine temperature gauge spikes and you’ve entered the danger zone, pull over and check the coolant overflow tank. A small leak, a loose hose, low coolant level – the causes of overheating are numerous, but you shouldn’t drive with a hot engine. Also, keep in mind that overheating doesn’t necessarily indicate a radiator issue. The thermostat could be stuck, or the water pump may be bad, so make sure to schedule an appointment so we can inspect it for you. This will help you to have a reliable vehicle when you will need to drive this winter.
