10 Best Antifreeze Coolants for Cars

1. Valvoline Multi-Vehicle 50/50 Prediluted Antifreeze Coolant

First on our list of the best antifreeze for cars is the Valvoline Multi-Vehicle 50/50 Prediluted  Antifreeze Coolant:

The only antifreeze that has Alugard Plus, a proprietary additive that makes it compatible with any other color antifreeze, is the Multi-Vehicle / MaxLife Antifreeze Coolant from Valvoline.

This universal formulation helps in extending the life of your car by moving heat from the engine to the radiator, keeping your vehicle’s engine temperature steady in all climates and driving conditions.

Other antifreeze manufacturers that claim to be suitable for “all makes and models” utilize a corrosion inhibitor package that does not contain silicate. When these chemistries are combined, the cooling system may be vulnerable to rust and corrosion.

  • Compatible with all vehicles and light trucks
  • It’s safe to use with any color antifreeze
  • Excellent rust and corrosion protection for all cooling system metals
  • Protects against freeze-ups in cold weather and boil-overs in hot weather
  • Protects the water pump, soldered joints, seals, and seams

2. ZEREX DEX-COOL Concentrated Antifreeze Coolant

Next on our list of the best antifreeze coolant for cars is the ZEREX DEX-COOL Concentrated Antifreeze Coolant:

The patented carboxylate formulation of the ZEREX DEX-COOL antifreeze coolant has a service life of up to 5 years or 150,000 miles. It protects all cooling system metals and aluminum with state-of-the-art organic acid technology in an ethylene glycol base.

General Motors has approved ZEREX DEX-COOL antifreeze coolant to the GM 6277M criteria. There are no silicates, phosphates, borates, nitrates, amines, or nitrites in the ZEREX DEX-COOL antifreeze coolant.

It is approved by Opel, Dae Woo, and Saab and can be blended with any DEX-COOL. It’s ‘orange’ because of its unique chemistry, distinguishing itself from the standard yellow and green silicate coolants.

ZEREX DEX-COOL protects modern engine components against freezing in the winter and boiling in the summer when diluted 50 percent with water. This antifreeze coolant can be stored for up to five years as a concentrate or diluted with water. It has a high-quality defoamer and won’t affect gaskets, hoses, plastics, or the paint on your vehicle.

  • OAT DEX-COOL Automaker Approved (for GM and SAAB vehicles)
  • Meets or exceeds industry specifications (ASTM D3306, SAE J1034, J814, J1941, TMC of ATA RP-302B, and federal specification A-A-870A)
