Most drivers never think about their car's radiator, yet it's a vital component of an engine's cooling system. It circulates fluid that draws heat from the engine and dissipates it into the atmosphere. If this system isn't functioning well, your car could overheat and suffer catastrophic engine damage. Thankfully, you can avoid that by learning the clues that signal auto radiator repair is necessary. Here's what you need to know.

How to Tell You Need Auto Radiator Repair

1. Cabin Heater Doesn't Work Well

The hot air that blows from your car's vents to keep you warm on chilly days depends upon the fluid running through the radiator. The heater may not work if the radiator is clogged, leaking, or otherwise not working correctly. If it blows cool or lukewarm air even after the engine has warmed up, it could indicate a problem with the radiator, a faulty thermostat, or a failing heater core.

2. Car Overheats

When a radiator works properly, the needle of the dashboard temperature gauge is centered, but a faulty radiator will cause the engine to overheat. You'll know it's overheating if the dashboard's engine temperature warning light (usually depicted as a thermometer in liquid) illuminates. If it rises into the red zone, the engine temps are abnormally high. Lastly, if steam pours from beneath the hood, it could mean the coolant has gotten so hot that it's boiling. 

3. Fluid Is Leaking

The engine coolant is often bright green, yellow, orange, or blue. If you spot puddles of liquid beneath the front of the engine compartment, it could mean your radiator is leaking fluid. Without coolant to carry heat away from the engine, the cylinder heads could warp, the seals could melt, and the head gasket could crack. Leaking fluid means you should have your radiator and cooling system inspected immediately.
