Whether you’re using your commercial generator for a pop-up event or a storm backup, your bottom line depends on a functioning electrical system. To ensure your generator's optimal performance, it's important to keep the system from overheating. Here's a guide to help you understand what causes this issue and how you can prevent the need for generator radiator repair.

How to Keep Your Commercial Generator From Overheating

What Can Happen If Your Generator Overheats?

If your commercial generator gets too warm, the internal parts will begin to burn. The most common problems associated with overheating include a singed alternator, which can cause the winding insulation and bearings to melt. This could also cause the rotor to warp out of shape and the slip rings and brushes to separate. Finally, overheating could limit the flow of coolant, enlarge the exhaust valves, and permanently damage the radiator core. Most systems will need serious generator radiator repairs or full replacements after such damage, and your business will be left without power until the work is completed.

What Causes Overheating?

Your commercial generator relies on a steady flow of coolant to avoid overheating. If the coolant levels are low or if the supply is leaking, the generator's temperature can quickly start to rise.

Overheating could also be a result of dirt and other contaminants on the generator’s exterior, as the excessive buildup could prevent the unit from gradually releasing heat. Other common causes of overheating include broken cooling fans, clogged diesel injectors, blocked exhaust valves, and dirty air filters, which can all limit the natural release of heat.

How Can You Prevent Overheating?

Since there are so many potential causes of overheating, scheduling regular and professional generator inspections is the best way to avoid a breakdown. Your technician can go down a thorough checklist to verify everything from coolant supplies to the exhaust pipes. 

Additionally, you can do your part by not overloading your generator. Add more units to your setup if your consumption needs rise, and keep them properly fueled. Keep the outside of the unit clean, as well, and ensure there are several feet of empty space around it at all times to allow the heat to escape.
