Coolant Concentrate HD

Coolant Concentrate HD is a concentrated antifreeze engine based on monoethylene glycol.

The package of additives it contains is designed according to the latest technology of inhibitor ingredients for the production of a final antifreeze that is free of amines, phosphate and silicate.

The combination of long-lasting organic additives with carefully selected metal inhibitors makes this technology extremely suitable for application in heavy-duty cast iron engines.

Advantages

When mixed with water in the right proportion, it provides the following advantages:
• Improved corrosion protection of all metals and especially cast iron which makes this product extremely useful in heavy-duty applications.
• Excellent protection of roller linings from the effects of corrosion.
• Thermal characteristics that allow efficient cooling of the engine without boiling.
• Eliminate deposition problems caused by the use of hard water.
Frost protection, depending on the selected concentration.
• Excellent anti-foaming properties.
• Complies with most European and international standards, including ASTM D6210.
• Suitable for use in applications that require the CAT EC-1 standard.

Performance

WEG Coolant Concentrate HD is a long-lasting antifreeze that must be replaced every five years or every 250,000 km for passenger cars or every 1,000,000 km for trucks and commercial vehicles. The recommendations of the original equipment manufacturers (OEM) should be followed when changing the cooling systems.

Compatibility

Although it is always recommended to use deionized or soft water to dilute the antifreeze, WEG Coolant Concentrated HD is designed to withstand different water qualities and is compatible with hard water.

Recommendations

In order to ensure a satisfactory level of corrosion protection, it is recommended to use at least 33% (1: 2) volume of product in the refrigerant solution. According to most car manufacturers, a 50% (1: 1) volume solution is recommended for optimal performance. For cold climates use a volume of 67% (2: 1), while concentrations above 67% are not recommended as they do not give an advantage.
