Your radiator is the unsung hero of your vehicle. Without it, your car overheats and that can cause any number of problems. With it, well, almost everyone forgets it even exists. Radiators can have issues, however. If your radiator has been ignored for too long or if you need radiator repair in Sandy Springs, here are some common radiator issues and what can be done about them.

Why It Matters

From clutch repair and joint repair all the way down to axle shaft repair, your car is a collection of systems that can go wrong at any moment. Each is critical to a healthy vehicle, but as mentioned, your radiator is in many ways the straw that helps stir the drink of an effectively functioning engine. When a radiator is defective, heat can cause wear on engine parts as well as deterioration of hoses, gaskets, water pumps and thermostats. All of that can shorten an engine’s lifespan.

Your engine runs between 190 to 210 degrees Fahrenheit. Without coolant, that wear on parts would accelerate. Radiator coolant keeps temperatures in check by cycling cooler coolant from the radiator into the engine as heated coolant is dumped back into the radiator and cooled by a fan.

Common Enemies of a Radiator


Chances are, when you think about a vehicle and rust, your thoughts center on the structural body and how rust can compromise that. Oxidation, which is what rust is, however, can happen anywhere there is metal and liquid, including a radiator. If rust is an issue with your radiator, the best-case scenario is that the coolant is not as effective. The worst-case scenario, where your radiator has to be replaced, is when holes develop from rust from the inside out and the radiator starts to leak. Rust is an issue in climates with a lot of cold, snowy weather because of salt being used on roads and the radiator being exposed almost constantly to liquid.


Leaks can come from rust, punctures, hose deterioration, clamps letting go and many other ways. The easiest way to determine you have a leak in your radiator system is when you smell the coolant. It's that sticky, sweet-smelling, green liquid that pools on the ground beneath the leak. The heat and pressure of a modern engine wear on hoses, clamps and your radiator and that can cause a leak that can cripple your engine.


Gunk can pile up at any point in your coolant system. Mineral deposits accumulate, harden and accumulate more mineral deposits. Once there are enough deposits and they are large enough, it affects the coolant flow, which can prematurely age your engine.

These are the three most common problems radiators experience and all three are avoidable with regular vehicle tune-ups. Ensuring you stay on top of your radiator situation will ensure you never need emergency radiator repair in Sandy Springs. If you do, get in touch with Mr. Transmission of Sandy Springs right away!
