Are there problems with the Ford Ranger breaking coolant hoses

Some Ford Ranger owners have reported that the hoses that carry coolant to the engine’s EGR valve have failed, allowing coolant to escape. This is one of the more common ways for this engine to lose coolant.

The problem with no warning showing up on the dashboard has more to do with physics. The warning light is triggered by the temperature of the coolant it’s submerged in. If the engine loses enough coolant, the sensor is suddenly not contacting the hot water and it ceases to give a reading or, therefore, trigger a warning. This is not a Ford Ranger thing, but a common problem faced by car owners over many decades.
