Delo® Coolants

Delo Coolant / Anti-freeze bottle

Effective coolants are vital to optimizing performance and maximizing engine life.

Delo ELC has dramatically simplified the way cooling systems are maintained, while delivering optimum performance. Our patented organic corrosion inhibitors eliminate the need for supplemental coolant additives and maximize hardware performance and heat transfer over the life of your engine.

Proven Protection — Reduced Costs

Millions of miles of on- and off-road use have proven that Delo ELC products provide exceptional performance and can help reduce cost of use when compared to conventional and fully formulated coolants.
