Van Wezel 37002338 Coolant, Engine Coolant

Van Wezel 37002338 Engine Coolant

The Van Wezel 37002338 Engine Coolant is a high‑performance liquid formulated to keep internal combustion engines operating within optimal temperature ranges. Designed for both passenger cars and light commercial vehicles, this coolant delivers superior heat transfer, corrosion protection, and long‑term stability.

Key Technical Features

• Optimal Temperature Range: Maintains engine temperatures between 70 °C and 110 °C, preventing overheating while ensuring efficient combustion.
• Corrosion Inhibitors: Contains a proprietary blend of phosphates, silicates, and organic acids that safeguard copper, brass, aluminum, and steel components from rust and scale buildup.
• Anti‑Foaming Additives: Reduces foam formation in the cooling system, which can otherwise lead to air pockets and reduced heat transfer efficiency.
• High Freeze Protection: Offers reliable protection down to -40 °C, making it suitable for extreme climates.
• Extended Service Life: Designed for a service interval of up to 60,000 km or two years, whichever comes first, without compromising performance.
• Compatibility: Fully compatible with aluminum and cast‑iron radiators, water pumps, and engine blocks commonly found in models such as the Opel Vectra C, Saab 9‑3, and other European vehicles.

Composition Overview

The coolant’s formulation is based on a ethylene glycol base, enriched with:

• Silicate complex – Enhances corrosion resistance and prevents scale formation.
• Phosphate buffer system – Maintains pH stability across temperature fluctuations.
• Organic acid blend (e.g., citric, tartaric acids) – Provides additional protection for copper alloys.
• Anti‑Foam agents (silicone‑based) – Keeps the coolant free from excessive bubbling.

Application and Usage Guidelines

For optimal performance, follow these steps when adding or replacing the coolant:

1. Ensure the engine is completely cool before opening the radiator cap to avoid burns.
2. Drain the old coolant through the designated drain plug, allowing any sediment to settle.
3. Refill with fresh Van Wezel 37002338 Engine Coolant until the level reaches the maximum mark on the reservoir.
4. Bleed the cooling system according to the vehicle manufacturer’s procedure to eliminate trapped air pockets.
5. Check for leaks and verify that the coolant level remains stable after a short drive.

Performance Benefits

• Enhanced Heat Dissipation: The high thermal conductivity of the glycol‑based mixture ensures rapid heat removal from the engine block, reducing wear and extending component life.
• Improved Fuel Efficiency: By maintaining optimal combustion temperatures, the coolant indirectly supports better fuel economy.
• Reduced Maintenance Costs: The extended service interval means fewer visits to the service center for coolant replacement.
• Environmental Compatibility: The product is formulated to meet stringent environmental regulations, minimizing ecological impact during disposal.

Compatibility with Vehicle Models

The Van Wezel 37002338 Engine Coolant has been extensively tested on a range of European vehicles. Notable models include:

• Opel Vectra C (2002‑2005) – Both 1.6 and 1.8 engine variants.
• Saab 9‑3 – Engine options from 1.6 to 2.0 liters.
• Other European cars with aluminum or cast‑iron cooling systems, such as certain models of the Volkswagen Passat and Skoda Octavia.

Storage and Handling Instructions

Store the coolant in a cool, dry place away from direct sunlight. Keep containers tightly sealed to prevent evaporation and contamination. Handle with gloves if desired, although the product is non‑toxic under normal usage conditions.

Environmental Considerations

• The coolant’s formulation reduces the likelihood of corrosion, which in turn lowers the frequency of component replacement and associated waste.
• When disposing of old coolant, follow local regulations for hazardous liquid disposal to prevent environmental contamination.

Conclusion

The Van Wezel 37002338 Engine Coolant stands out as a reliable, high‑quality solution for maintaining engine temperature and protecting critical components. Its advanced chemistry, proven compatibility with popular European models, and extended service life make it an excellent choice for both everyday drivers and automotive professionals seeking durability and performance.
