Coolant (antifreeze) is one of the key elements that keep a car engine running stably. The right choice and regular replacement help maintain optimal cooling and prevent overheating and corrosion in the system. This article explains how to choose high-quality antifreeze, how it differs from traditional coolant, and when you should have a coolant change in Wrocław.
Why is coolant important?
Coolant performs several key functions:
- Prevents engine overheating in summer and does not freeze in winter.
- Protects the cooling system from corrosion thanks to special additives.
- Extends the life of the radiator and hoses thanks to lubricating properties.
Without high-quality antifreeze, the cooling system can fail, which leads to costly cooling system repair.
Types of coolant
Coolants differ in colour and chemical composition. The most common types are:
1. Traditional (IAT – Inorganic Acid Technology)
✅ Colour: green or blue. ✅ Composition: inorganic corrosion inhibitors. ✅ Service life: up to 2 years or 50,000 km.
📌 Recommended for older car models, but they lose their properties quickly.
2. Hybrid (HOAT – Hybrid Organic Acid Technology)
✅ Colour: yellow, orange or turquoise. ✅ Composition: a mix of organic and inorganic additives. ✅ Service life: 4–5 years or 100,000 km.
📌 Used in modern European cars.
3. Organic (OAT – Organic Acid Technology)
✅ Colour: red, pink or orange. ✅ Composition: organic carboxylic acids. ✅ Service life: 5+ years or 250,000 km.
📌 The best choice for most modern cars.
