Motorcycle Engine Overheating – Causes and Ways to Prevent it

Engine Overheating is the most irritating thing for all users. Especially when it happens with Motorcycle. It causes major issues when someones drive a long time or if there is a long traffic jam. there are two types of Motorcycles based on the cooling system. one is air-cooled and another is liquid. Air-cooled Engines are suffered more in this problem. So let's see the common reasons for motorcycle overheating.

Initial Start

We know about gravity, it pulls all things down. It also happens when your motorcycle stands for a long time. So when you crank your bike for the first time of the day, please don't accelerate too much. Keep the engine at idle for some time then accelerate. At that time the Engine oil will do its job. So never ever rotate your accelerator too much for the first time. Give your vehicle some time, It called warm-up and it will make your engine live longer.

Carburetor Setting

The Engine generates heat and pressure and it happens for entering proper air-fuel mixture into the combustion chamber. So it's very important to make a proper mixture. But if the carburetor becomes failed to create a proper mixture and the air-fuel mixture becomes lean and enters the combustion chamber then it will create the Backfire. The backfire will turn the engine at an overheating condition.

Engine Oil Check

Engine oil reduces friction and makes your engine more optimistic. It also helps in cooling.  friction makes heat and if the oil becomes low or less then its ideal position than it might be a problem. So always keep your eye on the engine oil level. Engine oil must change every 3000 km if your motorcycle is the air-cooled engine. So always Enter correct grade oil to the engine and make your engine running healthily.

If your Engine is liquid-cooled than check this thing also:

When we say about the liquid cooling system then what comes to our mind? A Radiator, hose pipes, Coolants, etc. So whenever you found an overheating problem first check those things.

Coolant Check

It's a very common thing to prevent overheating problems. Always check your coolant level. An effective coolant is generally a 50-50 split between antifreeze and water. So make sure to do that for your coolant. But you have to change your coolant every 30,000 miles. Your owner's manual will give you the proper Details.

Faulty Radiators

The radiator is called a heat exchanger. the coolant from the engine gone through by radiator and the radiator fan makes them cold. It happens because the coolant goes by the radiator core and the fins spread the heat and it becomes cold faster. But if the radiator covered with lots of dust and different type of waste particles then what will happen? It won't be able to release heat from the coolant. That's why keeping the fins clean is very important for not overheat the engine. 

Radiator Fan

There is another reason for overheating. Your radiator fans are not working. Its very simple, If the fan doesn't perform his role then there is no one who will cool down the coolant. so make sure that your radiator fan is working.

Coolant Leak

The coolant should be on the correct level. If the level of coolant is below the recommended level then it might be a problem. So make sure that the coolant level is correct at all the time and it won't leak. The most common reason for coolant leak in a motorcycle is the loose radiator hose. That means the connection of the engine/radiator and the hose pipe is not good enough. So make sure all those connections are tight enough.





Engine overheating in motorcycles and cars may happen due to a lot of reasons. If you don't focus on them there will be times when your engine may seize. Regular checks from the mechanic will keep your engine happy and running without a mess. So take care of your engine and keep them a longer life.
