My Snowmobile overheats! Here’s why and how I Corrected it

Why snowmobiles overheat?

On the coldest days, when your snowmobile starts producing more heat than usual, you should notice and analyze. In the beginning, you write it somewhere, thinking maybe your sled feels warm because of that large mountain you arrived or the cool trick you just pulled off.

When the problem only gets worse as your day goes on, you realize you need to do something to find out the solution for the heated snowmobile. Do you ever wonder why do snowmobiles overheat and how do you fix the entire problem? Here is the answer to your question, snowmobiles can overheat from overdoing, lack of engine cooling, using the wrong petrol, and poor engine stator coil insulation. In some cases, bad electrical links or a damaged voltage regulator-rectifier can also cause overheating in the snowmobiles. Moreover, refilling coolant and giving your sled a break, it is not a bad idea to see a repair person for an overheating snowmobile.

In this article, we will give more details on both the causes and corrections of snowmobile overheating. The next time such a thing happens to you when riding your sled, you will know just what to do to fix it.

Why Do Snowmobiles Overheat?

First of all, let us figure out the main causes of snowmobile overheating. A little bit of overheating, such as while you are running your engine, is normal. As you ride your sledge, the heat exchangers will get covered in snow and the inner temperature of your snowmobile should then go down.  Nevertheless, in the following situations, overheating is usually the symbol of a more serious problem, so make sure you proceed with the proper channel.

·        Overuse

Do you need to be aware of how long have you ridden your snowmobile in a day? Has it been hours since you have taken a break? Maybe you have only gone for upwards of 60 minutes, but you were riding at extremely high speeds because you found the best trial with lots of open spaces in it.

In both these situations, you can expect your snowmobile’s engine to start overheating at some point. This issue will usually fix itself upon you stopping the sled and leaping off for a while. If you keep on continuing to ride the snowmobile when it is giving off a lot of heat, it could damage the engine, and in the most serious cases, it might lead to sled failure.

·        Lack of Coolant or Oil

As the name suggests, coolant is intended to flow through the engine partition and prevent the engine from getting too heated up. All you need to do is to constantly examine your coolant levels in your snowmobile. Without coolant, your engine is much more likely to overheat, so that could be one reason it is getting heated up.

In Addition to the coolant, another important fluid in sled care is the oil. When your snowmobile starts to run out of oil, the fuel mixture within can send heat to the engine, which causes it to get heated. If the engine gets hot enough, the rings and the piston heads can even melt, which will take control of your engine and prevent you from riding any further.

·        Broken Engine Fans

If a snowmobile is not liquid-cooled, then it has a fan for the system of cooling it down. A series of fans near the engine blow cool air its way so the engine does not overheat. One advantage of fan cooling is it is usually more maintenance-free compared to using coolant. Any of those fans can stop working, and when they do so, the cool air the engine collects maybe not enough to prevent overheating.

·        Filling up with the Wrong Kind of Fuel

Using the wrong type of gas for your snowmobile can cause the sled to power down and stop working instantly. For example, oxygenized fuel, or that which is ethanol-blended, leads to a leaner fuel mixture that will affect your snowmobile performance compared to filling up with pure gas. If your gas has too much water stored in it, that is also not good. Your gas may be thinner if it is ethanol-based because ethanol promotes more water consumption as it pulls in moisture from outdoors.

This combination of water and alcohol can outweigh the gas in your tank, splitting and turning into gunk that can travel to your engine. Your gas, now separated from the ethanol and water, has a much lower octane rating than before. If you are not familiar, the octane rating is a fuel source’s level of performance. To avoid these fuel issues, never buy blended fuel. Additionally, go to a gas station with employees you trust who will never guide you wrong.

·        Bad Stator

Another part of your snowmobile that could be a factor to overheating issues is the stator. Do you wonder what is the stator? Basically, a stater is found in most electric engines, the stator is one component within a rotary system. Energy gets passed through the stator as the rotating system spins.

The stator can go bad if you ride your sled for extended periods right after buying it, as the heat gets caught within the engine. The stator’s insulation, which hides the stator wires, could begin to break down, increasing the risk of the wires short-circuiting. At this point, you are at risk of engine failure.

·        Degraded Electrical Connections

The wiring within the stator is not all that can fail. As snow stuck into some parts of your snowmobile, the heat within causes the snow to melt. As A Replacement For of becoming a liquid, due to the high temperatures, the melting snow turns into steam. If you have had your sled for a while, the steam accumulation could cause electrical connectors to break down, even if they are weather sealed.

The metal terminals within the connectors will become decayed in a hurry. This increases your electrical system’s resistance, which can also alter your voltage regulator-rectifier.

·        Worn-Down Voltage Regulator-Rectifier

A voltage regulator-rectifier is a device that is constructed to control the voltage within the sled. Though, due to the steam buildup that can destroy the integrity of the aforementioned electrical connection as well as raise the challenge of the electrical system, the wiring harness’ connectors can boost the output of the voltage regulator-rectifier.

What this means is that instead of managing voltage to a reasonable degree like the voltage regulator-rectifier usually does, it believes the electrical system can handle more voltage because its output has increased. As more voltage flows through the system, the stator gets overloaded and breaks down.

How to Treat Snowmobile Overheating

Okay, so for one or more of the above reasons, your sled is overheating seriously. You understand now that continuing to ride your snowmobile when it is giving off so much heat is not a very good idea. Above and Beyond the engine, crucial interior components are also overheating, which could at any time cause the sled to stop working.

Here is what you should do when you feel your snowmobile get hotter than usual.

·        Check Your Coolant Levels

First of all, you want to gain access to your coolant tank to see how much coolant your sled has.as most snowmobile coolant is green or orange in color, so look for fluid in either of those hues.

·        Check your fuel levels

You should also check your fuel too while you are at it. It is best if you always fuel up fresh rather than use fuel you have sitting around at home. Within about a month, combined gasoline is a risk to use, and even pure gas might not be as pure and clear as it once was. You can even speed along the gas’s lifespan by storing it in a emitted container or the fuel tank, so don’t use either of these.

·        Take a Break

If both your fuel and coolant levels are okay, then it is time to move onto the other causes of your snowmobile overheating. For instance, have you may be ridden the sled too long or too quickly? If this is the case, then the best thing you can do is take a break, as we said earlier. This will give the internal components of the engine a much-needed chance to cool down so they can continue operating your ride for the second half of your day.

·        Add a Radiator or Fan

What some sledders do to prevent overheating is to add extra equipment to the rear of their snowmobiles. Either a radiator or an additional fan can keep air moving so the engine does not get too hot, even if you ride for a while.

This solution can work, but it does have several downsides. For one, you are adding more bulk to the back of your sled, which can make maneuvering a little tough in some instances. Also, the outdoor temperature has to be especially cold. Otherwise, the fan is just blowing warm air into the engine, which will speed up its overheating.

·        See a Mechanic

If you have tried everything, we have suggested to this point, but your snowmobile still continues to overheat, then we would suggest taking it to a sled mechanic. They can diagnose some of the more specific issues that can cause problems snowmobile cooling, such as broken-down wiring or a failed voltage regulator rectifier that you might not be able to identify yourself.

Final Thoughts

Snowmobile overheating is a frequent issue, but this can never be ignored. When your sled becomes hot, you are at danger of your engine failing, as well as other parts of your snowmobile.

Through this article, you now know just what to do when your snowmobile starts getting unusually warm. Good luck and stay safe out there.
