Hyundai Elantra Radiator

What Went Wrong with Your Hyundai Elantra Radiator?

The radiator has one of the most crucial tasks of regulating the temperature of the engine while allowing the car to functioin properly. There's no room for error with the radiator. Once it is incapable of getting the job done, the engine and other components will definitely suffer the same fate eventually, if not instantly. Your radiator breaking down in the middle of the road could be tremendously frightening, and knowing what went wrong can be as equally challenging. The following information will aim to give you confidence by undertaking radiator troubleshooting, so you can be aware of the problems that can arise from a declining radiator.

Defective parts

Your Hyundai Elantra radiator does its job efficiently and effectively because of the combination of a lot of internal parts that work together. Given that they are all exposed to huge levels of pressure, a myriad of flaws could surface and affect the overall performance of the radiator. For example, the thermostat of the radiator can fail at some point; and because of this, the radiator won't be able to get a reading of the engine's temperature. Consequently, the radiator won't be able to properly regulate the engine temperature and is in danger of overheating. Another case in point is a broken cap. Broken caps tend to get loose and let debris get inside the radiator. The rubber seal at the underside of the cap easily gives up under stressful conditions. Rust and corrosion are also not good signs because they can eat the metal up and mess with the water and coolant flow.

Engine overheat

The most obvious sign of a failed radiator is overheating. It usually starts with your car getting unusually high engine temperatures. This can originate from low coolant levels circulating in the radiator. Coolants are the escape pods of heat generated by the engine. Once the coolant absorbs the heat, the radiator cools it down so that it can go through another round back to the engine. A good rule of thumb is to have a full coolant reservoir, especially on dry and hot seasons. Likewise, debris within the lines and the coils in the radiator can get stuck and hinder the delivery of coolant to and from the engine.


A Leak is an inevitable sign of radiator failure as the car gets older. The radiator and its parts can get worn out given their task. Leaks are bad news because the precious coolant that flows and works its magic through the cooling process will escape. Once the coolant reservoir reaches dangerously low levels, the engine can't be kept cool for long. You can detect a leak by just smelling a distinct, sweet scent coming from under the hood. By this time, the radiator or the hoses have already been holed up. Either way, worn-out parts must be replaced as soon as possible.

  • Keeping It Cool with Hyundai Elantra Radiators

    When you think about it, the radiator is a very simple piece of machine. Much of its design has been left unchanged because it is effective at what it does: cooling down the hot engine. Because of this, maintaining it is not that difficult. There are just a few things you need to keep in mind for proper radiator maintenance. These basic steps can definitely give you peace of mind against the horrors of engine failure because of an ill-kept radiator. Following a maintenance routine is crucial for the overall health of the vehicle.

    Drain and flush your radiator.

    Draining and flushing the radiator can do a world of change for your car's health. Through the years, residues build up within the cooling system. These could potentially clog up the hoses, which serve as a delivery system of the radiator. Draining the coolant out every one to two years will clear out these harmful residues. After doing this, flushing the radiator will be a favorable follow up. Flushing will eliminate the rust and deposits that make your coolant appear brownish. Just remove the radiator cap and remove the radiator drain plug located below the engine to drain and use a radiator cleaner to flush out the rust and sediments.

    Change worn-out caps, hoses, and fittings.

    The radiator cap, hoses, and fittings are the parts that need frequent changing. These are made with rubber that can get brittle and less elastic. The dry and damaged parts can be an exit point for the coolant to escape from the radiator. Replace when the components in the cap get loose. You can do a radiator pressure test to see if there are holes in the cap, hoses, and fittings that rob your radiator out of pressure.

    Be cool with the coolant.

    The coolant, which also serves as antifreeze for winter, is the lifeblood of the engine cooling system. Without it, the engine will be crippled. The good thing is: coolants now contain protective additives that keep rust and corrosion away from the internal parts. Always check the coolant level and replenish habitually. A good mixture is equal amounts of water and coolant. Consult the owner's guide for the right mixture.
