What are the two types of coolant in cooling system?
There are three main types of coolant that car companies use: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT). Typically, older cars use IAT. It needs to be changed every two years or 24,000 miles, making it far inferior to newer formulas.
What’s the difference between red and blue coolant?
Antifreeze mixes with water to form a covalent bond to prevent the water from freezing. Antifreeze Blue is a full concentrate which meets BS6580 and contains the same pure ethylene glycol and anti-corrosive additives as the Red. Its application is for protection for up to a maximum of 2 years.
How to drain and refill a fully sealed cooling system?
Tighten all the hose clips and close all the bleed screws. With the engine running and hot, keep topping up the radiator as the air bubbles are dispersed. Trapped air tends to collect at the highest point of the system. Where there are no bleed valves, slacken the return hose of the heater unit – the bottom hose – and allow the air to escape.
