Temperature control in an engine is very vital for the survival of all its component parts. Even more is its importance of that engine is a diesel engine . We all know that engines that operate on diesel are very powerful and deliver an enormous amount of energy and heat. This heat generated needs to be controlled for continuous use. Should this control be absent, there will be consequences, and this will surely ruin your diesel engine and ultimately render your vehicle useless. In order to prevent this, your engine’s cooling system has to be at peak performance at all time. A slight drop in performance can result in overheating. Overheating in your diesel engine is not something you want to allow for an extended period, damage may come sooner than you expect. Should you notice your temperature gauge going over the acceptable limit, then its time for some repairs. There are different reasons your engine will overheat, below are some of the root causes:
Your coolant is leaking
If your coolant is leaking, it means there are holes, cracks, and breaks in your cooling system that shouldn’t exist. You can easily tell if your coolant is leaking if you notice an excessive and unusual drop in the amount of coolant in your vehicle. Coolants are colorful fluids, sometimes pink in color, if you observe it around your engine, then there’s a leak somewhere. A visit to a diesel engine mechanic can fix this problem for you.
Your coolant fluid is contaminated
Sometimes, the presence of impurities which could be corroded metal parts, rust, and even air bubbles could be the problem. The presence of these impurities dilutes the coolant, contaminates it and prevents it from functioning properly. Should this be the case, its time to flush out your coolant. Coolant fluid flush is recommended for your vehicle regularly. Don’t wait for your engine to display symptoms of overheating before you take your vehicle for a fluid flush.
Your cooling fan is broken
If your cooling fan ceases to operate, your engine will definitely overheat under as short a time as 10 minutes. You absolutely can’t drive your vehicle in this situation. The problem could be an electrical fault or that your fan is just broken. Whatever the case, take your vehicle to a diesel engine mechanic you trust so repairs and replacements are made accordingly.
Your radiator hose is compromised
This can take the form of a broken, collapsed or clogged hose. Should any of these happen, water will cease to flow properly and you n the right amount, hence overheating is certain. A mechanic will recommend replacing the broken/collapsed hose or remove the debris in the hose. It only takes a visit to to the mechanic to fix this.
Your thermostat is faulty
When your thermostat is faulty, it is unable to regulate the operations of your cooling system. Overheating is not debatable: here your engine will definitely overheat. You will have to replace the thermostat to get your cooling system performing again.
Your diesel injectors are clogged
When your diesel injectors are clogged with debris, fuel doesn’t flow as it should. Little fuel is provided for combustion leaving your engine to work harder to compensate for the loss. Extra work means more heat is generated by the engine. Frequent injector maintenance can help stymie this problem before it gets any worse.
If your diesel engine is facing any of these problems, don’t put off going to a mechanic any longer. The wait will only make the overheating get worse, and ruin the whole engine.
