Snowmobile Overheating: Causes and Solutions of Overheating

Winter is a season of holidays and enjoyment for many people around the world. While some people enjoy it for the rest, others enjoy it for the snow and winter sports like skiing or snowmobiling.

Even if you’re out there in the cold weather, it’s possible that your snowmobile may get overheated.

If you’re thinking about just ignore the overheating issue, and enjoy the ride, then you should think again. Overheating can cause many problems.

So, let’s take a look at the possible causes of overheating, problems it can cause, and how to deal with them.

Can you Ride a Snowmobile if it overheats?

If you are sure that you are using the snowmobile correctly in the right environment and found it to overheat during the normal use too, take your time and revisit all the points. Do not use it further as it can be dangerous for both the sled and for your safety too!

Overheating the engine can be a normal behavior up to a certain point. It the snowmobile overheats during the long ride, you may have to sit for thirty to forty minutes so that it has enough time to cool down and adjust to the correct temperature. This normally has to allow you to return to riding and also get more kilometers, but if you notice it heat again, you may have to stop and let it cool again.

Does Snowmobile Overheat on Ice?

Yes, the snowmobile overheats on ice while you ride. In this case, there are multiple reasons why the machine would behave in that way. Before checking into the technical details, it is good to do a checklist of all the things you might have missed. For example, Engine Oil.

If there is an insufficient amount of fuel running down the motor, oil would be the cause of the overheating problem. The rider should also make sure that the sled has enough coolant and also has to verify if there are some leaks, etc. If you have checked all of them and if the snowmobile is still overheating on ice, you should start digging a little deeper and check the snowmobile’s engine. To run properly, the snowmobile should have the main three components that are crucial.

  • Air Mixture/Fuel
  • A Spark
  • Compression

Any of the above can also encounter problems when you turn on your sled, these can cause your machine to overheat, stop running and also underperform.

Is Overheating Dangerous for your Snowmobile?

It is said that in a normal year, over two million people enjoy the snowboarding in just North America. Statistics show us that snowmobile activity is not as dangerous as perceived. But it is also said that over two hundred people die in accidents and there are also 14,000 people having injuries due to the snow machines every year.

However, just like any other machine, this can be dangerous if it is not working properly. The rider has to take into account all the other variables that may lead to overheating of the snowmobile.

Having the engine overheat is never a satisfying or normal behavior, it can surely be unsafe and dangerous. You can find yourself far from a specialized service to have a look at it. You should also double-check if the engine has anti-freeze, enough oil, and if there is a possibility of leak that causes disruption in the engine.

What Problems Overheating can Cause?

A few common problems among the snowmobile heating can come from the snowmobile stator that is the failure of the regulator-rectifier; or damaged wiring harness or the connectors, shortened, corroded, etc.

If you happen to notice the snowmobile overheating, you should test it more to see if the problem resurfaces. Overheating of the Snowmobile should not be avoided as it may later cause different technical issues like losing pistons, rings, and other important components.

For example, if the snowmobile overheats right before you start to ride it, the machine will shut down before the same overheats and not after. The computer inside has to shut down the machine after around three minutes of idling in case the temperature rises over the safe and normal temperature.

In this case, usually the sled gets warmed up around 100-150 degree F, and as such, any temperature that passes by is considered overheating and the computer should be shut down instantly to protect the engine.

Causes of Overheating in Snowmobile

Snowmobile Overheating Issues

Snowmobile stators fail for several reasons. The most common cause is the overheating, the failure of the regulator-rectifier, shorted or damaged wiring harness or connectors. Below are a few mentioned.

Overheating Stator

The Snowmobile stators fail due to overheating. A snowmobile stator is mounted inside the motor which is a very hot environment to be working hard in. The High-quality snowmobile stators are built with extremely effective insulation on their wire windings to withstand the heat, while the cheaper parts generally sacrifice the quality of the wire.

Voltage Regulator-Rectifier Failure

The Voltage Regulator-Rectifier on your snowmobile also fails due to the high amount of heat. This may be caused by using a low or cheap quality regulator with subpar electronics, or fatigue due to the age of the part. This may fail by causing short-circuit, which draws a high current from the snowmobile sector. This, in turn, increases its heat and causes it to fail.

Corroded, Shorted or Damaged Wiring harness/Electrical Connectors

Snowmobiles are constantly subjected to the melting snow that turns quickly into steam around a hot snowmobile engine. This steam may leak into even weather-sealed electrical connectors on the sled. It then quickly gets to work corroding the metal terminals and also inside the wire insulation that can cause high resistance in your electrical system. The increased resistance in your connectors and the wiring harness may cause your voltage regulator-rectifier to increase the output and eventually overloading the stator that may fail from the increased heat.

What to do if your Snowmobile overheats?

If you notice your snowmobile overheating, there are multiple things that you need to check. At first, check if there is a sufficient amount of fuel running down the motor. Check the Coolant, compressor, etc.

If there is still a mild overheating while riding, you may also add an extra fan and the radiator on the backside of the motor sled. This will keep the temperature level to normal in case you have to ride it for a long time. Another remedy to overheating is to buy scratchers. The scratchers are the main element that keeps the engine cooler.

If the snowmobile overheats during a long ride, then you need to let it sit for at least thirty minutes in order to have enough time for it to cool down and also to adjust with the correct temperature.

Although if you still find your vehicle overheats more than the normal and that you have already followed all the above-mentioned steps and have found there are no any damages or leaks, it is mandatory to contact a mechanic to take a look at it. Waiting passively for the same to pass might do further damage for the same and you may end up in losing more than a few hundred bucks for the concern.
