Coolants For Late Winter/Early Spring: Complete Guide

As winter lingers and temperatures remain unpredictable, it’s crucial to ensure your vehicle is still protected. At Finol Oils, we know that the right coolant and antifreeze are essential year-round, but especially during these late winter months. Choosing the wrong type—or worse, mixing incompatible coolants—can lead to engine damage, breakdowns, and costly repairs.

With our expertise in coolants and antifreeze, we help garages and mechanics select the best products to keep vehicles running efficiently. Here’s why using the correct coolant still matters as we transition into spring.

Why Coolants Are Still Essential in Late Winter

Even though winter is easing, coolants continue to protect your engine in several key ways.

1. Freeze Protection

Cold nights can still freeze unprotected cooling systems, causing severe damage. Our premium coolants prevent freezing down to -37°C, ensuring your engine stays protected no matter the temperature drop.

2. Temperature Regulation

Coolants don’t just stop your engine from freezing; they also help regulate heat, ensuring optimal fuel efficiency and preventing overheating during fluctuating temperatures.

3. Corrosion Prevention

Winter roads expose vehicles to moisture and grime, all of which accelerate corrosion. Our coolants contain advanced corrosion inhibitors to protect metal components from rust and wear.

4. Efficient Heat Transfer

Even in cold weather, engines generate a lot of heat. Using the right coolant ensures efficient heat dissipation, preventing overheating and maintaining peak engine performance.

Choosing the Right Coolant Matters

Not all coolants are the same. Using the wrong type or mixing different coolants can compromise performance and lead to engine failure. Here’s a quick guide to the most common coolant types:

How to Choose the Correct Coolant

1. Check Your Vehicle’s Manual – Always follow the manufacturer’s recommendations for the correct coolant.
2. Don’t Be Tempted by Universal Coolants – Cheaper products claiming to suit all vehicles often lack the necessary formulation for specific engines.
3. Use Colour as a Guide—Not a Rule – While coolant colours can indicate their type, always check the product label and specifications.
4. Premix Concentrate Antifreeze Properly – If you’re using a concentrated coolant, mix and agitate it properly with water in 50:50 ratio before adding it to your cooling system. Alternatively, you can choose a Premixed/Ready-to-Use solution for convenience.
