Sinopec Great Wall FD-1 Low Freezing Point Multi-Effect Engine Coolant All-Season Protection

Sinopec Great Wall FD-1 Low Freezing Point Multi-Effect Engine Coolant All-Season

Great Wall FD-1 -25C Low Freezing Point Multi-Effect Engine Coolant

Great Wall FD-1 is a multi-effect engine coolant with a low freezing point and a high boiling point, supplied as a bright green transparent liquid. Designed for use throughout mainland China, it delivers year-round, all-season protection for automotive engines and offers a service life of 1 to 2 years or up to 50,000 km.

Product Overview

This engine coolant keeps the cooling system stable across a wide temperature range. Its cooling performance suits the cooling systems of cars used in cold climates, while its excellent corrosion inhibition provides long-term protection for all metals in the cooling system. A high-efficiency cavitation inhibitor further prevents the various forms of cavitation that can occur in the cooling systems of heavy duty engines.

Key Advantages

• Low freezing point and high boiling point for four-season, all-weather use.
• Excellent corrosion inhibition that provides long-term protection for all metals in the cooling system.
• Contains a high-efficiency cavitation inhibitor to prevent cavitation in heavy duty engine cooling systems.
• Excellent cooling performance for the cooling systems of cars used in cold climates.
• Withstands a 1064-hour simulated-use test, with test coupons staying bright as new.
• Long service life of 1 to 2 years or up to 50,000 km.

Typical Data (FD-1)

Applications

• Cars and trucks that require engine coolant.
• Modern engines with aluminium and diesel cast-iron liners needing long-term, high-temperature corrosion protection.
• Gasoline, diesel, LPG and CNG powered engines.
• Heavy duty engines where cavitation protection is important.

Why a Multi-Effect Coolant Matters

Engine temperature changes quickly between cold starts and sustained driving. A coolant with both a low freezing point and a high boiling point keeps the cooling system within a safe range, reducing the risk of freezing in winter and overheating in summer. Because a cooling system contains several different metals that can corrode at different rates, and because vibration can trigger cavitation in heavy duty engines, a multi-effect coolant with strong corrosion inhibition and cavitation protection helps extend the reliability of the cooling system all year round.

Frequently Asked Questions

Storage and Handling

Store the coolant in its original, tightly closed container in a cool and dry place away from direct sunlight. Keep it out of reach of children and do not mix different coolant products unless the manufacturer confirms compatibility. Dispose of used coolant in line with local environmental regulations.

Quality and Supply

Each batch of Great Wall FD-1 engine coolant is produced under a controlled quality system and checked before release. Verified performance in a 1064-hour simulated-use test and compliance with recognised standards make it a practical multi-effect engine coolant for distributors, workshops and fleet operators who need consistent, all-season cooling protection.
