To get your generator up and running, all you may need to do is fill up the fuel tank and flip a switch. However, this powerful engine has to perform a number of tasks to generate electricity for your property. As a result, it can easily overheat. If you’re hoping to avoid the need for generator radiator repairs, use this guide to learn how to prevent high internal temperatures.

3 Reasons Why Your Diesel Generator Is Overheating

1. Clogs

Your diesel generator needs lubricant to stay cool, as the fluid reduces friction between the moving metal parts. However, if the lubrication system gets clogged, it won’t be able to flow through the machine any longer. Some of the most common blockages form in the radiator or pipeline, while others occur in the exhaust pipe.

Since the latter prevents hot emissions from escaping the cylinder, heat can build up rapidly inside the generator. If you haven’t changed the oil filter in your generator recently, this part may become clogged with contaminants and contribute to overheating.

2. Leaks

In addition to clogs, a lack of lubricant may also be caused by leaks. If the fluid itself leaks out of the diesel engine, the generator will have no way to stay cool. Most of the time, leaks occur from the radiator or pipeline.

However, gaps may also pop up in the oil pan or pump, especially if there is a loose seal or gasket. As the fluid seeps out, you might notice it pooling on the floor beneath your generator.

3. Wear & Tear

Even in the best scenarios, a generator will start to exhibit signs of deterioration after long periods of heavy use. Unfortunately, this wear and tear can lead the machine to overheat, and eventually, break down. For example, if the fluid pump—which is responsible for moving the coolant around the hot components—wears down, it may not be able to work fast enough to combat the rising temperature. Conversely, if the cooling fan breaks, the machine won’t be able to shed heat as easily.
