## Overview

Lubegard 96430 Heavy Duty 2-in-1 Coolant Treatment is a 32 fl. oz. powerhouse formula designed to protect engines from corrosion, chemical electrolysis, and cavitation erosion. It prevents scale and slime buildup that leads to overheating, while extending the lifespan of water pump impellers and seals. Made in the USA, this treatment ensures heavy-duty, long-lasting coolant system performance.

## Description

Lubegard Heavy Duty Coolant Treatment outperformed all other supplemental coolant additives (SCAs) to such a degree that it effectively stands in a league of its own.The Penray PenCool 2000 and PenCool 3000, Cummins Fleetguard DCA-4 and Lubegard HD coolant treatment were all tested using ASTM certified procedures. These tests allow evaluation, and benchmarking, of corrosion protection performance. They included ASTM D4340, ASTM D1384, and ASTM D2570. Each of the products passed these tests, with the exception of the PenCool 2000. It failed due to its inability to provide adequate corrosion protection of aluminum. The Lubegard 2-in-1 heavy duty coolant treatment passed all tests with the most margin to spare. It provides aluminum protection with newer, proprietary organic technology than it's competitors. Additionally, Fleetguard utilizes phosphate for pH buffering - an ingredient that Detroit diesel does not permit for use in their systems.Lubegard contains no phosphate, and receives across-the-board OEM acceptance. It contains wetting agent ingredients, which provide engine temperature reduction performance - eliminating the need and expense of using an additional product like Red Line diesel water wetter. Testing has shown that the polysiloxane in water wetter polymerizes to form a nasty layer of slime within the radiator. Lubegard does not contain any polysiloxane ingredients. The treatment eliminates the need to buy multiple products. It is the only supplemental coolant additive that contains complete corrosion protection and wetting agents, all in one. It is chemically engineered to reduce the surface tension of coolant, allowing it to more deeply penetrate metal surfaces at vital heat-transfer areas. This decreases operating temperatures and significantly reduces the possibility of engine overheating.This product does not contain ethylene glycol.
