You know how hot your engine gets if you’ve ever opened the hood of your car after driving it for a time. The radiator circulates coolant through your vehicle’s engine to protect it from overheating and maintain a steady temperature. However, if the radiator fails and the engine overheats, you may be in for some big (and costly) repairs. To avoid a more catastrophic problem, be aware of the warning signals that you need to repair your radiator.
- Your Vehicle Is Overheating
Of course, this is the most obvious indicator of a radiator problem, and if your engine is overheating, you should pull over immediately and let it cool down. White steam coming from beneath the hood is an indication of an overheated engine. If you keep driving while your car is hot, the engine may seize or the piston may melt and fuse with the cylinder, necessitating an engine replacement.
- The temperature on your thermometer rises.
After your automobile has warmed up, your dashboard instrument panel features a temperature indicator that normally displays that your engine’s temperature is roughly halfway between cold and hot. Unless anything is amiss, it should never rise over the middle. If the needle on your temperature gauge is creeping toward the hot end of the scale, have your radiator examined right away. You may only want extra coolant, but you do not want to risk irreversible harm by driving it while it is hot.
- Rust Is Appearing on Your Radiator
Because your car’s radiator is constructed of metal, it will rust if it is exposed to moisture for an extended period. If your radiator has rust on it, there might be a leak in the radiator hose or the radiator itself. The coolant squirts out of the hole and onto the radiator due to the leak. Even though the fluid will burn off rapidly owing to the heat, moisture patches will remain, which will rust.
- Your car is leaking a brightly colored fluid.
If you detect a bright green, yellow, or pink fluid under your car, you most likely have a coolant leak. This might be due to a leaking radiator hose or the radiator itself, but it must be fixed before all of your coolants runs out and your car overheats. Not only that, but coolant keeps your engine from freezing up in the winter, so it’s not only for the summer.
- Your coolant levels are dangerously low.
Checking your coolant level (and other fluid levels) regularly might alert you to potential concerns if the level is low. If you have an exterior coolant leak, you’ll notice a pool of colored fluid on the ground; however, the sole sign of an interior coolant leak is a lower-than-normal coolant level. Add enough coolant to your radiator, but also take it to a service shop as quickly as possible to locate and correct the leak. These five indicators of a radiator problem will alert you to the fact that you should take your car to a repair shop for a radiator examination right away.
