Technician a says that oat type coolant should be changed every 2 years. technician b says that iat type coolant should be changed every 2 years. which technician is correct?

Technician B is correct i-e IAT type coolant should be changed every 2 years.

Explanation:

Coolant is one of the most important fluid for the car as it prevents the engine from overheating during summers and freezing during winters. What it does is that it actually lowers the freezing point during summers and increases the boiling point of the system during summers. There are different types of coolant used by different cars. Among which, two of them are:

1)OAT i-e Organic Acid Technology

2)IAT i-e Inorganic Additive Technology  

IAT type coolants are usually used by older cars and generally should be usually replaced every 2 years. While, the other type which is the OAT type coolant should be replaced every 5 years.

Thus, Technician B is correct i-e IAT type coolant should be changed every 2 years.
