Ford Bronco II Radiator

How to Identify Warnings of a Waning Ford Bronco II Radiator

Being the main component of engine cooling, a lot of responsibility rests on the shoulders of a radiator. Once it is unable to do its job properly, other parts of the engine will definitely follow suit. A lack of knowledge in the proper identification of radiator problems seems like a goodbye ticket for your Ford Bronco II. By undertaking radiator troubleshooting, you can be aware of the problems that can arise from a waning radiator. Therefore, diagnosis and repair will be so much easier. 


The most famous indicator of a waning radiator is overheating or even unusually high engine temperatures. This can originate from incorrect coolant levels in the radiator. Coolants are avenues of escape of the heat generated by the engine. The radiator makes sure that the coolant doesn't get too hot once it goes back to the engine. It's always good to have a full coolant reservoir, especially on dry and hot seasons. Similarly, any contaminants that can get caught within the lines and the coils in the radiator could contaminate the coolant and hinder its job of alleviating the heat from the engine.


As the car gets older, the radiator and its parts can get worn out. Leaking is one of the earliest signs of this. Any leak coming from the radiator is bad news. You can detect this by a distinct sweet smell or green liquid directly below the engine where the radiator is located. If this happens, there might be holes in the radiator or the hoses. This can also happen if some freak accident happened to puncture your radiators. Either way, worn out parts must be replaced immediately.


The radiator might be one single block of an engine component but a lot of internal parts work together to make sure that it does the job of cooling the engine. Since it is exposed to high amounts of stress, a bunch of defects can affect the radiator. This can result to more problems for the vehicle. For one, if the thermostat of the radiator fails, the radiator won't be able to properly regulate the temperature of the vehicle. Another example is a broken and loose cap. Aside from not letting any debris get inside the radiator, the cap also regulates the pressure inside once it gets pretty hot. The seal at the underside of the cap is made of rubber, which easily gives up under stressful conditions. The presence of rust and corrosion is not a good sign, especially for the radiator. It can eat up through the metal and mess up with the water and coolant flow.

  • Proper Maintenance of Ford Bronco II Radiator

    The radiator is not a complicated piece of machinery and therefore, its maintenance doesn't have to be difficult. One thing you must remember is: the maintenance of a radiator mainly revolves around the fluids that are used in cooling the engine. This basic maintenance can deliver the desired upkeep for maintaining the optimal temperature of the engine and the radiator. Following this maintenance routine is vital for the overall health of the vehicle.

    • Remember that coolant is important.
    • The coolant, or antifreeze for freezing days, plays a big part keeping your engine in good working state. In addition, it also provides the proper temperature regulation properties for your radiator also. Nowadays, coolants go beyond the ability to keep your engine running under extreme temperature variations. Coolants may contain other additives that help the internal parts of the radiator prevent rust and corrosion. Never neglect this prime fluid. It is recommended that the coolant be replaced every year. Basically, a good coolant mix is a 50/50 equal parts water and coolant. However, this always depends on the vehicle. Consult the owner's guide for the right mixture. Remember that coolants are toxic. Always arm yourself with the proper working gear.
    • Drain and flush your radiator every one to two years.
    • Over time, sediments may build up within the car's cooling system. Therefore, it's necessary to drain out the coolant from time to time to clear out anything that can clog and potentially damage the system. Aside from coolant replacement, it is also a good idea to flush the radiator every one to two years to ensure the cooling system will run well. This is regardless of the car's mileage. An indicator of a radiator that is in desperate need of flushing is when the coolant appears to be dirty or brownish, and if you there are little rust specks floating around. Coolants are typically bright hued in color: yellow, orange, or green. To do this, just raise the car on ramps, cool the engine down, remove the radiator cap and remove the radiator drain plug. Make sure a bucket is underneath to catch all the fluid. You can also use a radiator-cleaning product to fully flush out the rust and sediments.
    • Check the radiator cap, hoses, and fittings.
    • With time, the radiator cap becomes dry and damaged and because of this, coolant will escape from the radiator. Replace the cap as needed. Also, check the hoses and fittings because they can lose their elasticity and become brittle. Punctures in the hoses and fittings will also allow coolant to escape and leak out from the engine. To know if the cap, hoses, and fittings aren't leaking out pressure, perform a radiator pressure test.
