A radiologist is a physician or medical specialist trained in obtaining and interpreting medical images. Images may be obtained with x-rays, (CT scans or radiographs), nuclear medicine (involving radioactive substances, magnetism (MRI), or ultrasound.
Without radiator coolant, an auto engine would overheat extremely fast, leading to mechanical breakdown and engine failure. While oil may be the lifeblood of a carâs engine, coolant is like the water that helps to dispel heat. In fact, coolant mixes with water in a carâs radiator. It prevents the water from freezing and boiling given the extreme temperatures it is exposed to.
Ford uses two different temperature sensors. One is called the engine coolant temperature (ECT) sensor and the other is the engine cylinder head temperature (CHT) sensor. This article concentrates on the engine coolant temperature sensor (see photo below). This DTC tells you that the PCM is seeing a coolant temperature of -46Â° F (-50Â° C). 2  This DTC indicates one of several things: 3  Coolant temp sensor's wires have an âopenâ short (usually due to a cut wire). 4  Coolant sensor's connector has become unplugged from the sensor itself. 5  Coolant temp sensor is BAD. 6  PCM is BAD.
