EVANS EC53001 High Performance Waterless Engine Coolant
Designed for modern, classic, and vintage gasoline engines, plus light diesels and LP/CNG variants, this coolant features a boiling point of 375°F and will not vaporize, helping prevent boilovers. It generates low vapor pressures, minimizes coolant loss, and reduces strain on cooling system components. Containing no water, it effectively reduces corrosion, liner erosion, and water pump cavitation while lowering maintenance costs. Suitable for industries seeking long-term cooling reliability and reduced maintenance intervals.
EVANS Coolant EC53001 High Performance Waterless Coolant (4 Gallon Pack)
This high-volume pack is built for the same versatile vehicle range as the single 128-ounce version. It maintains a 375°F boiling point, eliminates boilover risk, and minimizes vapor pressure. By containing no water, the coolant reduces corrosion and cavitation risks across a fleet or multiple vehicles, potentially delivering extended service life and lower total cooling-system maintenance costs over time.
EVANS Coolant EC72064 Powersports Waterless Engine Coolant
Specially formulated for powersports equipment, including motocross, trail, Enduro, street bikes, quads, ATVs, UTVs, and snowmobiles, this coolant contains no water, effectively removing corrosion and cavitation erosion risks. It reduces maintenance costs and protects high-performance engines operating under demanding conditions. Suitable for vehicle owners seeking reliable protection in compact, high-revving engines.
EVANS EC31001 Collectors Choice Waterless Engine Coolant
Targeted at vintage and classic gasoline vehicles, along with light to medium duty diesels, this product generates low vapor pressures and prevents coolant loss. With a boiling point of 375°F, it won’t vaporize, helping to prevent boilovers in historic or restoration projects. The formula focuses on reducing strain on cooling system components while maintaining dependable operation for classic engines.
EVANS Coolant Powersports Waterless Engine Coolant
Packaged for ATVs, UTVs, quads, snowmobiles, and street bikes, this coolant contains no water, eliminating corrosion and cavitation erosion. It minimizes the potential for electrolysis-related issues and reduces ongoing maintenance costs, making it a practical choice for mixed-use or seasonally driven powersports fleets seeking reliable thermal management.
EVANS EC10064 NPG Waterless Engine Coolant
Evans NPG (Non-Aqueous Propylene Glycol) coolant is designed for racing venues that permit propylene glycol-based coolants and for settings where ethylene glycol is not allowed. This waterless formulation supports high-performance racing environments while avoiding glycols that are restricted in certain venues or service settings.
PEAK DEX-Cool Antifreeze + Coolant
PEAK DEX-Cool is a versatile OAT-based coolant designed for GM vehicles from 1995 onward, offering rust and corrosion protection for cooling system metals including aluminum. It has a lengthy service life of up to 150,000 miles with a full flush and fill, and includes Denatonium Benzoate to deter ingestion. Note that this product uses a traditional coolant chemistry rather than a fully waterless system.
Buying Guide: Key Purchase Considerations
- Vehicle compatibility: Confirm your vehicle’s engine type, age, and manufacturer guidance. Waterless formulations may be ideal for modern, classic, or performance engines but check compatibility with your cooling system materials and radiator design.
- Boiling point and vapor risk: Waterless options typically offer high boiling points to prevent boilovers. Consider your climate, driving style, and operating temperatures when selecting a coolant with strong vapor suppression.
- Maintenance profile: Waterless coolants generally reduce corrosion, cavitation, and maintenance costs, but may require specific refilling procedures or service intervals. Ensure you have access to compatible replacement products and know the flush/fill requirements.
- Application scope: Powersports, race venues, and vintage restoration needs may favor specific Evans formulations (e.g., NPG) or volume options. Choose a product aligned with your activity and fleet size.
- Safety and compliance: Some blends include Denatonium Benzoate or other additives to deter ingestion or meet racing standards. Review safety data and any venue-specific rules before purchase.
- Volume and packaging: For households or fleets, packs with multiple gallons or quarts can reduce per-unit cost and simplify maintenance scheduling. Ensure your storage space accommodates the container size.
- Installation considerations: Waterless coolants may require specific engine and cooling-system preparation. Follow manufacturer installation guidelines to avoid air pockets, improper cooling, or warranty issues.
Choosing the right waterless coolant involves balancing vehicle type, usage patterns, and maintenance expectations. The products highlighted above cover a spectrum from classic cars to modern engines and powersports, providing options for single-vehicle use or larger fleets. Always consult your vehicle’s service manual and the coolant supplier’s guidelines to ensure proper selection and ongoing performance.
