Many vehicle owners underestimate the importance of proper coolant, sometimes topping up with plain water or using the wrong type of antifreeze. This seemingly minor oversight can lead to catastrophic engine damage.
Why Water Alone is Insufficient: - Water boils at 100 degrees C — engine operating temperatures often exceed this - Water freezes at 0 degrees C — causing expansion that can crack engine blocks - Water causes corrosion of aluminum, iron, and copper components - Water provides no lubrication for the water pump seal - Water allows electrolysis that erodes metal surfaces
What Proper Coolant Provides: 1. Freeze Protection: A 50/50 mix protects to -37 degrees C 2. Boil-Over Protection: Raises boiling point to approximately 108 degrees C (higher with pressure cap) 3. Corrosion Inhibitors: Protect all cooling system metals 4. Water Pump Lubrication: Extends pump life 5. Anti-Foam Agents: Prevent cavitation damage
Coolant Types: - IAT (Inorganic Acid Technology): Traditional green coolant, requires replacement every 2 years - OAT (Organic Acid Technology): Extended life (5+ years), typically orange or red - HOAT (Hybrid OAT): Combines IAT and OAT technologies, various colors - Si-OAT: Silicate-enhanced OAT for European vehicles
Never mix different coolant types without flushing the system first. Mixing incompatible coolants can cause gelling, reduced protection, and clogged passages.
Our i-GlooKool range includes both concentrated and pre-mixed formulations in multiple ratios (30/70, 40/60, 50/50) to suit every climate and application.
