Ford Focus Radiator Troubleshooting Guidelines
Tired of dealing with persistent overheating problems involving your Ford Focus radiator? You might be troubleshooting the wrong way. Read on for some basic steps in diagnosing a problem with your Ford Focus radiator. Do it right, or you might just lose a cooling system that always ensures you a cool and worry-free ride.
Focus on the bottom and underside.
Once you notice leaks, especially on the area where you usually park your Ford Focus, inspect your radiator and focus on the bottom and underside parts. These areas are particularly vulnerable to damage as they are the parts most exposed to harmful elements, like road debris and rocks.
Check the other parts too.
Malfunction in your Ford Focus radiator can also be caused by defects on the other components of the cooling system. Do not limit your inspection to the radiator body. Include the hoses, the water pump, and the gasket seal. If any of these are damaged, then leaks can occur, affecting the performance of your Ford Focus radiator. Aside from damage or leaks, a loose hose might also cause the radiator troubles. A radiator hose can loosen due to vibrations in the engine. Check how firmly the hose is attached and make necessary adjustments. As for the water pump and gasket seals, check for damage and/or leaks by looking for traces of fresh coolant, or visible oxidation.
Inspect the radiator fan.
Problems in the Ford Focus radiator may also be caused by a defective radiator fan. There are a handful of probable causes, and the radiator fan must be checked for each one. First, the disengagement of the fan might be caused by the malfunctioning of the temperature switch. Second, the fan motor could have burned out, resulting in the inactivity of the radiator fan. Lastly, the fan might not be activating because the thermostat has completely gone out, giving wrong temperature readings to the cooling system.
Take a look at the resistors.
If you are having some bizarre troubles with your Ford Focus radiator, like the fans activating at a pace more than the usual, then the root cause might be the resistors. The resistors might have burned out, causing the radiator malfunction. To verify this, you can check the resistors at the back of the glove box.
