Make sure your Honda car or SUV is staying cool at all times by paying attention to the thermostat in your vehicle. The radiator is one of the most important parts of the cooling system in your vehicle. It is responsible for maintaining the temperature of your engine by using a set of hoses and a fan to cool it down if it gets too hot. It can struggle to regulate temperatures over time and cause your car to overheat if it wears out, so make sure you make replacements as soon as you notice any problems with it. There are some things you can keep an eye out for that can indicate issues. You might find your vehicle overheats often. This shouldn't be happening, especially under normal driving conditions. This is the number one sign of a radiator failing, because it is the only thing that is responsible for keeping your engine cool. You also might see coolant pooling under your vehicle when you park it somewhere. This can indicate a leak or crack in the coolant hose or somewhere else in the radiator system.
