Antifreeze & Engine Coolant

Protect engines and cooling systems with antifreeze and engine coolant from Keller-Heartt. Shop coolant for passenger vehicles, heavy-duty trucks, fleets, repair shops, and commercial equipment in a variety of formulations and package sizes.

Choose from Truegard, ShellZone, and other coolant options, including conventional and extended-life formulas, ready-to-use coolant, concentrates, 55-gallon drums, and other bulk quantities.

Find the Right Antifreeze & Coolant

The right coolant helps regulate engine temperature while protecting cooling-system components against freezing, overheating, corrosion, and deposits.

Coolants aren't all interchangeable. Different vehicles and engines can require different chemistries and specifications, so always check the vehicle or equipment manufacturer's requirements before choosing a product.

Conventional Antifreeze & Coolant

Conventional coolant is used in many automotive and equipment applications. Depending on the product, it may be sold as a concentrate that needs to be mixed with water or as a pre-diluted, ready-to-use formula.

Shop Conventional Coolant

Extended-Life Antifreeze

Extended-life coolant is formulated to provide longer service intervals when used in compatible cooling systems. Keller-Heartt carries extended-life antifreeze and coolant options for automotive, fleet, and heavy-duty applications.

Frequently asked questions

Find answers to common questions about our products and services

  • The terms are often used interchangeably, but antifreeze generally refers to the concentrated fluid used in an engine cooling system. Engine coolant may refer to either the concentrate or a pre-mixed solution of antifreeze and water.

  • Color can help identify some coolant products, but it should not be used by itself to determine compatibility. Different manufacturers can use similar colors for different coolant chemistries. Always select coolant based on the required specification.

  • Concentrated antifreeze generally needs to be mixed with the appropriate amount and type of water before use. A 50/50 coolant is already pre-diluted and typically ready to use when compatible with the application.

  • Extended-life coolant is formulated for longer service intervals than some conventional coolants when used in an appropriate cooling system. Actual replacement intervals should still follow the vehicle, equipment, and coolant manufacturer's recommendation

  • It can be. Fleets that regularly service vehicles can use bulk coolant to maintain a centralized supply and reduce reliance on individual containers. Fleet managers should first determine which coolant specifications are required across their vehicles.
