5 Best Coolant For Snowmobiles: (Buyers Guide)

Best Coolant For Snowmobiles

Snowmobiles are high-rev power sport engines that get hot and require a specific type of coolant to prevent engine damage and enhance reliability and performance. Which coolant will protect your snowmobile the best?

Learn what brands and types work best in the 5 best coolants for a snowmobile buyer’s guide to understand what coolants to use, and why.

The best coolant for snowmobiles is Engine Ice Hi-Performance Snowmobile & Winter Coolant + Antifreeze. It provides versatile protection for all types of snowmobiles when OEM product is unavailable. The advanced formulation protects against heat and cold extremes, protects cooling system components better, and it’s biodegradable.

Can You Use Regular Automotive Coolant In Your Snowmobile

Regular automotive coolant is not formulated to meet the requirements for snowmobile engines.

High rev engines can overheat when pushed to the limits under adverse riding conditions, creating strain on the engine, and overheating without the maximum protection from the coolant.

You may get by but you’re taking a risk. Powersports coolant is formulated with ethylene glycol to protect from engine heat to 226 degrees Fahrenheit to prevent damage but also provides freeze protection from temperatures to -35 degrees Fahrenheit.

Coolants that contain borate, nitrite, and phosphates deplete fast, leaving your machine vulnerable.

They leave deposits in the system, increasing heat transfer and risk for damage.

Powersports formulations offer benefits of cleaner running, prevention of leaks, heat transfer, and corrosion to internal parts.

Coolants that do not meet OEM standards can cause damage to gaskets, hose materials, and metal parts over time.

How Much Coolant Does A Snowmobile Take

Most snowmobiles hold approximately a gallon of coolant. Each manufacturer provides specific recommendations for the amount of coolant required.

It’s essential to refer to the manual to know the best antifreeze formulation for the model, the coolant-to-water ratio, and the amount it will hold.

It’s safe to plan on a gallon in most cases unless you’re directed to do otherwise by the manufacturer.

Underfilling a snowmobile with coolant can result in overheating and damage to the machine. Optimal amounts are recommended at all times.

Keep extra coolant on hand, check the levels regularly, and replace as needed.

How To Choose The Best Coolant For Snowmobiles

1 – Refer To The OEM Requirements For Your Brand/Model Snowmobile

Each snowmobile manufacturer understands the engine design and which products provide optimal reliability, performance, and protection.

OEM coolant and formulations with the same ingredients and ratios will work.

2 – Confirm The Temperature Protection Range

Compatible coolants will meet the maximum heat your snowmobile engine produces.

They must also protect the coldest environmental conditions your sled encounters.

Confirm the range for the best protection.

3 – Buy High-Quality Formulations

Some coolant formulations contain ingredients that dissipate quickly, like borate, nitrite, and phosphates.

Avoid these coolants if possible.

4 – Consider A Pre-Mix

If you’re unsure of the best ratios for mixing snowmobile coolant, buy a premix.

It’s a little more expensive, but it can save time, effort, and guesswork.

5 – Maintain Optimum Coolant Levels

Antifreeze dissipates over time and with frequent use. Confirm the level of coolant in your snowmobile before and after use.

Don’t run the machine if the levels are low or you’ll lose the protection and put your machine at risk of damage.

Helpful Tips To Know About The Best Coolant For Snowmobiles

Know the facts about the best snowmobile coolant for your snowmobile. Some riders substitute OEM antifreeze for comparable formulations, but manufacturers do not support the reasoning.

Don’t risk voiding a warranty by using the wrong type of coolant, as damages to your sled may not be covered.

  • Choose the recommended coolant for your brand and model snowmobile. Adhere to the manufacturer’s requirements to avoid voiding your warranty.
  • Not all coolants are suitable for use in snowmobiles. Only precise formulations per manufacturer requirements will protect your vehicle from damage.

Final Thoughts

The best coolant for snowmobiles is a genuine OEM brand that is compatible with the brand and model of the machine you own.

Some coolants that meet the specifications and formulations of OEM fluids are the best second choice if nothing else is available.

Compatibility with your engine is essential to prevent damage to your cooling system or engine.

Going outside of the guidelines for optimal operation puts your machine at risk for damage and could void your warranty.

Even if no warranty exists, consider the cost of repairs before you take the chance. It’s better to go with the recommendations whenever possible.
