It wasn't like a normal leak.no coolant was on the ground.It went through the exhaust system. This is what an EGR cooler does. 😀 😛
An EGR (Exhaust Gas Recirculation) Cooler is a heat exchanger installed in the EGR circuit. The EGR system recirculates exhaust back to the engine in order to reduce NOX (Nitrous Oxide) emissions. The cooler simply cools the exhaust gas prior to gas being reintroduced into the engine. By cooling the gas the combustion temperature is reduced and NOX also as NOX is formed at higher temperatures.
Various cooler (heat exchanger) technologies are used by manufacturers, although tube and shell is the most common type used currently. Coolers will vary in size depending on the engine size and the emission standard the engine must comply with.

Very interesting. Not at all like the radiator on a car. 😀 😛
