Mitsubishi Eclipse Radiator

Troubleshooting your Mitsubishi Eclipse Radiator

Getting your Mitsubishi Eclipse stuck in the middle of the road due to an overheated engine doesn't sound really cool. This road mishap is usually caused by a worn-out radiator. So if lately you have been experiencing higher engine temperature while driving your car in high speed, better check your radiator for leaks or damage. Here are some troubleshooting tips that might help you understand your Mitsubishi Eclipse radiator better:

Engine overheating

If the engine overheats while you are driving, give it at least 30 minutes to cool down before checking the cause of the problem. Once the engine has cooled down, check the system for rotting or burnt hoses that might have caused the coolant to leak and burn. You can also check if the radiator is clogged by inspecting if the coolant is flowing correctly. If the thermostat and the hoses are working perfectly, the radiator is more likely to be clogged. Also, check the coolant by smelling it. If it smells like mud water or rubber, then the radiator is indeed the cause of the problem. You have to replace the radiator or perform a radiator flush to clean it.

Coolant contamination

If you have been experiencing frequent overheating, it could be due to a coolant contamination. Coolants come in different colors depending on their brands. However, don't ever combine two different colors of coolant. This would result in a gel-like substance that won't flow and only hinder the passageway to the engine system. When this happens, it could cause engine overheating and damage to the head gaskets and other components. Other substances that are mixed with the coolant would only contaminate it, except for water. It is advisable to have an equal mix of water and coolant for the radiator to function efficiently.


Since the radiator is exposed to all kinds of road debris such as dirt, moisture, and dust, it is most likely to wear out due to corrosion. When this happens, it can make the radiator more susceptible to breaking and failing. Check the radiator for rust spots and replace it before the corrosion totally eats it all up.

  • Mitsubishi Eclipse Radiator Maintenance Tips

    A sport compact car as sleek and as fast as the Mitsubishi Eclipse should never be caught stranded in the middle of the road due to an overheated engine. This is often a result of a cooling system issue. The radiator is one of the parts of the cooling system that is prone to premature wear, which causes the engine to overheat. Good thing, you can do some easy and quick steps to keep your radiator in its good condition, thus, preventing engine problems. Here's how you can keep your radiator clean and cool:

    Maintain the right level of coolant.

    Make it a habit to always check the level of your radiator's coolant before you start your car. This is to ensure that there will be no loss of coolant once you are on the road. A leak on the cooling system can cause the coolant to escape, which could lead to overheating the engine. Pour in only the right amount of coolant required to keep the system running. Make sure to refill once or twice a year.

    Conduct a "radiator flush" regularly.

    A clogged radiator makes it harder for the coolant to effectively do its job. Dirt and other debris can cause the radiator to clog and to wear out faster. By performing a radiator flush, all the grime and dirt buildup will be cleansed. An affordable radiator flush solution is all you need to pull this off. Afterwards, you can fill the radiator with a new coolant. Do this every year and see the difference it will do to your cooling system and to your engine.

    Replace leaking parts.

    The cooling system is composed of several parts that are prone to premature wear, such as hoses, head gaskets, and radiator. You can look under your vehicle if there is a colored liquid spill on the ground. If it's coolant, then you should check the radiator for coolant deposits or rust spots. You should replace the radiator immediately before the problem gets worse. Watch out for cracked and bent hoses as they can be the next culprits to cause coolant leaks.
