Ford Ranger Radiator

Spotting Problems with Your Ford Ranger Radiator

Your Ford Ranger Radiator is a heat exchanger that works for your engine. It transfers the heat from the coolant into the air that blows by it. This ensures that the coolant being circulated back into the engine block would prevent overheating. However, damage and problems can occur with your radiator. If not spotted immediately, these grow worse and lead into an engine issue. With this, you need to be watchful for the slightest signs of radiator problem. Following are some signs that would help you determine an issue with your radiator.

Fluctuating temperature

Sudden changes in temperature are the easiest signs to detect. If your temperature gauge shows drastic changes in the temperature in your vehicle, there may be an issue with your Ford Ranger radiator. It can be due to clogged radiator, faulty thermostat, or bad water pump. Before you make necessary actions, pinpoint which part is actually at fault.

Bubbles or steam

Your radiator may exhibit bubbles or steam coming from its body. These are clear signs of a leak. Damage in the radiator can be caused by external factors such as road salt. It can corrode the metal in the radiator, making a hole or crack. Corrosion may also be due to freezing. When there is lack in antifreeze, water would expand and damage the radiator body.

Overheating at idle

If your SUV works fine while driving fast but overheats at idle, there may be an issue with the radiator fan. Cool air has to be blown into your radiator to reduce coolant temperature. In the case of a faulty fan, no air cools the coolant down. This is fine when driving on a freeway as the air you pass by would do the job. But when you are at idle or stuck in traffic, nothing would force feed cool air into your radiator.

Discolored coolant

Another common visual sign of a radiator going bad is discolored coolant. Your coolant is supposed to be green or yellow. When it starts to go oil- or rust-colored, it means that corroded particles are mixed into the coolant. This would make way for sludge formation that can clog the radiator tubes and hoses. Flushing is necessary when you see radiator sludge.

  • Ways of Taking Care of Your Ford Ranger Radiator 27 February 2013

    Your engine cooling system functions as a support feature in your SUV by protecting your engine from overheating. A major player in this system is the radiator. It works as a heat exchanger by transferring the heat from the coolant into the air that blows by it. This way, the coolant that circulates around the engine block maintains its low temperature. A small problem with your radiator can result in serious damage in the engine. With this, you need to properly take care of this part. Following are some simple ways on how you can guarantee your radiator would serve your engine for the longest time.


    Clean the car after driving on snow.


    During winter season, salt is being sprinkled into the road to melt the snow. The bad news is that road salt damages the metal components of your Ford Ranger radiator. Leak and corrosion may develop if road salt is not removed immediately. With this, it is recommended that you clean your car and your radiator after driving on snow.


    Purchase the correct radiator cap.


    Aside from securing coolant inside your radiator, its cap also serves as a pressure release valve. It maintains the pressure inside the radiator at a constant boiling point. A bad radiator cap can cause many problems and may even result in engine overheat. With this, you need to make sure your radiator has the correct cap. It is recommended that you always buy a radiator cap that can handle up to 15 psi of internal pressure.


    Avoid overdosing on antifreeze.


    Many owners tend to overdose on antifreeze during the winter season. They think that the more antifreeze they put, the more freeze protection their engines would get. However, this is a long-going myth. Antifreeze products are formulated to be mixed with water at 50/50 ratio. During the winter, you can have more antifreeze at 69/31 solution. Anything more than that can damage the radiator and the water pump.


    Flush your radiator every year.


    Flushing is the best way of cleaning your Ford Ranger radiator. The process removes rusts, scales, and contaminant deposits in your radiator and its tubes. It also gets rid of your old coolant which tends to become dirty and acidic.
