Shell Dex-Cool Extended Life Antifreeze Coolant — 50/50 Pre-Diluted 1 Gallon, Silicate-Free Corrosion Protection

Shell Dex-Cool ELC 50/50 is a pre-diluted, extended-life ethylene-glycol coolant formulated to protect modern engines and cooling-system metals for up to 5 years or 150,000 miles in automotive use.

Designed as a single-phase, silicate-free coolant with a carboxylate inhibitor system, Shell Dex-Cool ELC offers long-lasting corrosion protection for aluminum, brass, cast iron, steel, solder and copper while maintaining efficient heat transfer. This ready-to-use 50/50 gallon provides a convenient, OEM-compatible option for passenger cars and many light-duty trucks that require Dex-Cool performance levels.

How does this coolant protect engine metals over time?

Shell Dex-Cool ELC uses a carboxylate-based inhibitor package that forms protective layers on metal surfaces to resist corrosion without relying on silicates. That chemistry helps preserve water pump seals and radiator passages while minimizing buildup that can hinder heat exchange.

• Formulated for aluminum, brass, cast iron, steel, solder and copper protection
• Silicate-free to reduce gel and scale formation in service and storage
• Maintains as-new heat transfer performance for efficient cooling

Is this coolant compatible with my vehicle and service intervals?

Shell Dex-Cool ELC meets multiple OEM specifications including GM GMW3420/GM6277M, Chrysler MS-12106, Ford ESE-M97B44-D and Volkswagen/Audi G-12, making it suitable for many vehicles that call for Dex-Cool or G-12 type coolants. For typical automotive applications the product supports a five-year or 150,000-mile interval; heavy-duty, non-nitrite systems can see much longer service windows.

• Pre-diluted 50/50 for immediate use—no mixing required
• Meets GM, Chrysler, Ford and VW/Audi OEM specifications
• Automotive service life: up to 5 years / 150,000 miles

What benefits does the silicate-free formula provide for performance?

By avoiding silicates, this coolant reduces the risk of silicate gel formation that can restrict flow and lower heat transfer efficiency. The result is sustained thermal performance and potentially longer component life for water pumps and radiators under normal operating conditions.

• Improves long-term heat-transfer stability
• Reduces potential for silicate-related deposits or blockages
• Supports improved water pump life through reduced abrasive particles

How should I use and store this pre-diluted coolant?

This one-gallon pre-diluted 50/50 solution is ready to pour into a cooled system; follow vehicle manufacturer instructions for correct top-up or fill procedures. Store sealed in a cool, dry place away from direct sunlight and extreme temperatures to preserve inhibitor stability.

• Ready-to-use 50/50 mixture—no additional water required
• Top up or replace coolant when vehicle is cool to avoid burns
• Store sealed container in a stable, temperature-controlled location

Who is this product for? Shell Dex-Cool ELC 50/50 (1 gallon) is aimed at vehicle owners, fleet managers and independent shops that need a reliable, OEM-compatible coolant tailored for aluminum-rich modern engines seeking extended service intervals. Choose this product if you want a convenient, pre-mixed extended-life coolant that supports multiple OEM specs and helps maintain efficient cooling without silicate-related issues.
