Engine Ice SXS/ATV Coolant 0.5 gal Premixed — Hi-Performance propylene glycol, lowers engine temps

Engine Ice Hi-Performance SXS/ATV Coolant + Antifreeze (0.5 gal) is a premixed, phosphate-free coolant that lowers operating temperatures and protects against freeze and boilover for side-by-sides, ATVs, and quads.

Engine Ice designed this half-gallon coolant specifically for high-demand off-road machines. It arrives ready-to-use (premixed with deionized water), uses propylene glycol rather than ethylene glycol, and relies on OAT-style inhibitors for corrosion resistance. The formula focuses on dispersing heat efficiently so engines run cooler under load without additional mixing or additives.

How does this coolant help keep my SXS or ATV running cooler?

The Engine Ice formula improves heat transfer so the engine sheds heat faster during sustained high-load riding. Independent testing shows average operating temperature reductions, which helps maintain power and avoid heat-related performance loss. It’s formulated for small cooling systems common to UTVs and quads.

• Average temperature drop of 10–20°F under typical loads
• Enhanced heat dispersion through special OAT-compatible additives
• Designed for compact radiators and limited flow systems

Is this product ready to use, and what protection levels does it provide?

Yes — the 0.5-gallon bottle is pre-diluted with deionized water and ready out of the bottle, so there’s no mixing required. It provides boil-over resistance up to approximately 256°F and freeze protection down to about −28°F, suitable for most seasonal conditions when used as supplied.

• Premixed with deionized water for immediate use
• Boilover protection near 256°F (vehicle-dependent)
• Freeze protection to roughly −28°F for moderate cold climates

Will it harm seals, hoses, or cooling system metals in my vehicle?

Engine Ice Hi-Performance is phosphate-free and formulated with OAT (organic acid technology) inhibitors to minimize corrosion across common cooling system metals. It uses propylene glycol, which is less aggressive than ethylene glycol for many elastomers, but always check compatibility with your manufacturer’s recommendations for seals and gaskets.

• OAT-based corrosion inhibitors for mixed-metal protection
• Propylene glycol base instead of ethylene glycol
• Phosphate-free to reduce deposit risks in small systems

How easy is it to install and maintain this coolant?

Because it comes premixed, installation is straightforward: drain old coolant if required, flush to manufacturer specs, and top up with Engine Ice. Routine checks of level and a periodic system flush per your vehicle’s service schedule will keep heat transfer optimal.

• No measuring or dilution — pour and fill to spec
• Compatible with standard cooling system maintenance procedures
• Best results when paired with a clean, debris-free radiator and proper coolant level

Who is this for: This 0.5-gallon Engine Ice Hi-Performance SXS/ATV Coolant is intended for owners and technicians of side-by-sides, ATVs, quads, and other small off-road vehicles who want a ready-to-use coolant that emphasizes lower operating temperatures and balanced freeze/boil protection. It’s a solid choice for riders who push their machines in hot or mixed climates and prefer a premixed, propylene-glycol-based formula that’s phosphate-free and compatible with common off-road cooling systems.
