AMSOIL Powersports Antifreeze & Coolant

AMSOIL Powersports Antifreeze & Coolant – Built For Hot, High-Revving Machines

AMSOIL Powersports Antifreeze & Coolant is a pre-mixed, ready-to-pour coolant designed specifically for ATVs, UTVs, motorcycles, snowmobiles, PWCs, and other powersports engines. It’s blended as a 50/50 ethylene-glycol and high-purity water mix, so you don’t have to measure or dilute anything—just drain, flush as needed, and fill.

The formula is built to control heat in hot-running, high-revving engines, protect against corrosion and scale, and provide all-season protection for up to five years, so you spend more time riding and less time messing with coolant.

Why Coolant Matters So Much In Powersports Engines

High RPM + Tight Packaging = Serious Heat

ATVs, UTVs, dirt bikes, sport bikes, snowmobiles and PWCs all share a few traits:

• High RPM engines
• Compact radiators and tight engine bays
• Lots of mud, sand, or deep snow packing around the chassis
• Long periods of sustained load

All of that stresses the cooling system. If the coolant can’t pull heat out and move it to the radiator efficiently, metal parts overheat, expand beyond tolerances, and you risk warped heads, blown gaskets or shortened engine life.

More Aluminum, More Sensitivity

Modern powersports cooling systems use a lot of aluminum in radiators, heads and blocks. Aluminum transfers heat well but is also sensitive to the wrong chemistry—cheap coolant or tap-water mixes can cause corrosion, pitting and deposits that eventually plug passages and kill heat transfer.

That’s why AMSOIL formulated this coolant specifically around the metals and materials common in powersports.

Key Features Of AMSOIL Powersports Antifreeze & Coolant

Pre-Mixed 50/50 Convenience

No Measuring, No Guesswork

This coolant arrives already mixed 50/50 with high-purity water, eliminating one of the biggest owner mistakes: mixing with tap water or getting the ratio wrong.

Benefits of the pre-mix:

• The freezing/boiling protection is predictable and correct
• High-purity water helps prevent mineral scale buildup
• Faster, cleaner service—just pour and go

If you’ve ever stood in the garage wondering “Did I mix this strong enough?”, this solves that.

Ethylene-Glycol Formula That Meets OEM Requirements

Proven Chemistry, Built For Powersports

AMSOIL Powersports Antifreeze & Coolant uses an ethylene-glycol base that meets OEM requirements for modern liquid-cooled engines.

That means:

• Excellent heat transfer
• Reliable freeze and boil protection
• Compatibility with most factory cooling systems that call for ethylene-glycol coolants

It’s not a “universal mystery mix.” It’s a targeted formula designed to slot into powersports applications that specify a 50/50 ethylene-glycol coolant.

Wide Temperature Protection: From Deep Winter To Peak Summer

Boil-Over Protection Up To 226°F (108°C)

In hard riding, especially in summer or under heavy load (towing, deep mud, slow technical trails), coolant temps can climb quickly. This product provides boil-over protection up to 226°F (108°C), helping prevent vapor pockets and overheating even in tough riding conditions.

Freeze Protection Down To –34°F (–37°C)

On the other end, it protects down to –34°F (–37°C), giving you true four-season capability for snowmobiles, winter ATVs/UTVs and cold-climate bikes.

If you live where the riding season stretches from summer dunes to winter trails, this one coolant covers it.

Keeps Engines Clean And Efficient

Fights Scale And Deposits

Mineral-heavy water and low-grade coolant can leave scale and deposits on:

• Radiator passages
• Water jackets in the head and block
• Thermostats and small passages

This buildup acts like insulation and blocks heat transfer, making the engine run hotter and forcing the fan and pump to work harder.

AMSOIL Powersports Antifreeze & Coolant is mixed with high-purity water and fortified with robust anti-corrosion and anti-deposit additives to keep systems clean and flowing.

Corrosion Protection For Metals And Components

The formula is safe for:

• Aluminum
• Copper
• Brass/bronze alloys
• Common gasket and hose materials

Heres what this helps

• Prevent internal corrosion and pitting
• Protect thin radiator tubes from pinholes
• Reduce the risk of leaks at hoses and gaskets

Protecting the cooling system inside means your engine holds its temperature more consistently, year after year.

Helps Prevent Cavitation Damage

High-revving engines and water pumps can create low-pressure zones that cause cavitation—tiny vapor bubbles that collapse and eat away metal surfaces. The product description notes that this coolant helps inhibit cavitation, adding another layer of protection to pump components and cylinder liners where applicable.

Extended Life: Up To Five Years Of Protection

Long-Life Chemistry

Some coolants are built on additive packs that deplete quickly, forcing frequent changes. AMSOIL Powersports Antifreeze & Coolant uses extended-life chemistry that’s borate-, nitrite- and phosphate-free, allowing a service life of up to five years under normal conditions.

Heres what this helps

• Less frequent coolant changes
• Lower maintenance time and hassle
• Peace of mind for seasonal machines that sit part of the year

Reduced Maintenance, More Riding

Because it’s long-life and premixed, you can:

• Service the system correctly once
• Check the level at each oil change
• Spend more time riding and less time draining and refilling coolant

It’s especially handy if you maintain multiple machines—one product, one interval, simple schedule.

Optimized For Powersports Metals And Materials

Built Around Aluminum-Heavy Systems

Modern powersports cooling systems often feature:

• Aluminum radiators and heads
• Small passages and tight fin spacing
• Lightweight alloys for weight savings

AMSOIL specifically calls out that this coolant is optimized for the metals found in powersports cooling systems, including increased aluminum content.

That optimization helps:

• Reduce aluminum corrosion and pitting
• Maintain efficient heat transfer surfaces
• Extend the life of radiators and heads

Compatibility With Most Coolants

The product is described as compatible with most other coolants, which helps if you’re topping off or transitioning from another brand.

However:

• Mixing coolants can make predicting freeze protection harder
• If you must mix to top off, plan a proper flush at the next convenient opportunity for best results

Why Not Just Use Generic Automotive Coolant?

Formulation Focused On Powersports Needs

Generic automotive coolant is designed around passenger cars and light trucks. Powersports applications differ:

• Higher sustained RPM
• Smaller coolant volumes
• More aluminum and lightweight alloys
• Tougher exposure to mud, dust, sand, deep snow and vibration

Powersports Antifreeze & Coolant is blended for these specific demands, with a focus on:

• Hot-running, high-revving operation
• Anti-deposit protection for small passages
• Compatibility with common powersports materials

Quart Bottles For Smaller Systems

Many powersports cooling systems don’t use anywhere near a full gallon. AMSOIL packages this coolant in quart bottles (and cases), so you’re not forced to buy more than you need, which is often the case with big automotive jugs.

For the typical ATV, UTV or bike:

• A couple of quarts is often enough for a full refill
• You can buy exactly the amount you need, avoiding half-used containers sitting for years

Practical Maintenance Tips (High Level)

(Always follow your machine’s service manual and safety instructions.)

Check Coolant At Each Oil Change: Good habits for better results:

• Inspect the coolant level in the radiator (when cool) and overflow bottle
• Look for discoloration, debris, or oily film
• Watch for dried coolant traces around hoses, clamps and water pump weep holes

If you see issues, it may be time for a closer inspection or service.

Service Life Up To Five Years

AMSOIL states that Powersports Antifreeze & Coolant provides all-season protection for up to five years.

However, you might choose shorter intervals if:

• You ride in especially harsh conditions (racing, deep mud, extreme heat)
• The machine sees a lot of hours each year
• You’ve mixed coolants or are unsure of what’s in the system

Changing coolant at sensible intervals is cheap insurance compared to engine repairs.

Flushing And Refilling

A proper service generally includes:

• Draining old coolant
• Flushing with clean water or a recommended flush product
• Refilling with fresh 50/50 Powersports Antifreeze & Coolant

Because coolant is hazardous, any used fluid should be disposed of responsibly according to local regulations.

If you’re not comfortable with cooling-system work, a shop can easily handle this as part of seasonal service.
