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.
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.
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.
