A Guide On Genset Cooling Repairs

by Debra Morgan

An overheating generator can cause downtime at your industrial premises or construction site. Unfortunately, most site managers do not understand the cause of generator overheating or how to conduct cooling repairs. Below is all you need to know about generator cooling repairs. 

What Are The Dangers Of Generator Overheating? 

Diesel generators are reliable and durable. As such, site and property managers forget to conduct regular inspections to establish signs of overheating. If a generator overheats for an extended period. It is bound to develop a few issues. The radiator is one of the immediate casualties once a generator overheats. Typically, the radiator core gets damaged since it is not built to withstand high temperatures. The generator's exhaust valves, bearings, rotors and cylinder head could either warp or suffer irreparable damage once the machine overheats. As the internal temperatures increase, the alternator windings burn, causing growling noises or stalling. A damaged alternator also prevents the generator from starting up. 

Causes Of Diesel Generator Overheating And The Required Repairs 

A generator could overheat due to various external and internal factors. For instance, low air density caused by high altitudes or temperatures compels the generator to work harder to develop the required power. As such, it is bound to overheat. Similarly, high humidity prevents heat dissipation, which could predispose the equipment to overheating. The generator could also overheat if you cover it or place it in a small room. In this case, the generator cannot dissipate heat efficiently. 

Poor maintenance and neglected inspection protocols could also cause overheating. For instance, leaking or damaged radiator hoses let out the coolant, significantly increasing the engine temperatures. In other cases, the radiator core gunk clogs the radiator core, preventing coolant circulation in the generator. A broken radiator fan could also cause the generator to overheat. Other culprits include clogged injectors or air filters, damaged exhaust, low oil levels and generator overload. 

Once the generator overheats, conduct a quick inspection to determine the cause of overheating. For instance, the generator could have low coolant levels or leaking pipes. Once you address the issue, run the generator for a few minutes under close observation to establish whether or not the issue will reoccur. If the problem reoccurs, shut off the generator and call a technician to repair the machine. Proper maintenance can help ease diagnosis when the generator overheats. For instance, you could rule out a clogged filter or injector if you have recently replaced the components. 

Keep these tips in mind when looking for generator cooling repair services near you.

Awesome auto service stories

I've been running an auto service shop for the past 30 years. The trends in cars have changed a lot over that time, and cars are becoming a lot more complicated and automated. People can't fix many items on their own cars any more as you need a computer to diagnose most issues. People use their cars a lot more these days as we live further away from workplaces and schools so it's important for me to be able to get cars back quickly. I have had to keep learning about how the new cars run and I keep a lot of hints on this site so you can all learn the things you can do to make your cars run better.
