Take Care of your Cooling System
Antifreeze is an often misunderstood product. Not only does antifreeze keep the water in your systems from freezing up, it also keeps your system from overheating. Keeping your fluids running at the correct temperatures helps maintain the life of the machinery and extends your productivity. It reduces maintenance cost and downtime and protects your system from extreme temperatures, corrosion, water pump failure, and more.
If your cooling system goes without care for extended periods of time, it can lead to air pockets bursting inside your engine, leading to pockmarks, irregularities, and corrosion. This, in turn, can cause cracked engine blocks, broken pistons, and total engine failure.
Whatever your machinery, we have the anti-freeze additives for you. Our approachable and experienced staff is trained in coolants and will guide you in what is best for your operation.
Windshield Washer Fluid
Our windshield washer fluid is our own proprietary blend, developed for consistent performance and improved visibility in all driving conditions. It effectively cuts through dirt, salt, and road grime while performing reliably in both warm and cold weather.
Keep the fleet Running responsibly
Diesel exhaust fluid was created in response to the 2010 Diesel Emissions Standards required by the EPA. DEF, combined with Selective Catalytic Reduction (SCR) technology, is used to reduce pollution from diesel vehicles and equipment by more than 90%. DEF is non-toxic, non-polluting, non-hazardous, and non-flammable.
The vast majority of engine manufacturers prefer SCR technology, making DEF a necessity when operating heavy equipment. Without proper fluid levels, your trucks will stop working and could potentially void any warranties you may have on your equipment.
Offering convenient, secure deliveries of our high-quality DEF at wholesale prices to keep your fleet in action.
Quality Matters
Contaminants can cause harm to your DEF system. That is why STERN limits the transfers of DEF and only handles product through certified micromatic fittings that prevent contamination from coming in contact with the product or your system.
