As an owner of a 5.9 Cummins engine, I have learned the hard way that a coolant bypass is essential for the proper functioning and longevity of my engine. The purpose of a coolant bypass is to divert a portion of the coolant flow away from the engine block and back to the radiator. This may seem counterintuitive, but there are several reasons why this is necessary.

Firstly, the 5.9 Cummins engine is known for its high operating temperatures, especially when under heavy load or towing. This means that without a coolant bypass, all of the coolant would be constantly circulating through the engine block, resulting in it being heated up and struggling to maintain a consistent temperature. This can lead to overheating and potential damage to important components such as gaskets and seals.

Secondly, by diverting some of the coolant flow back to the radiator, a coolant bypass helps to regulate the temperature and prevent hot spots within the engine block. This is crucial for maintaining optimal performance and preventing premature wear and tear on critical parts.

Furthermore, having a coolant bypass also allows for faster warm-up times in colder climates. By not immediately directing all of the coolant through the engine block, it allows for some heat to remain in the radiator and aid in warming up the
