Is there a water flow through the radiator?
Is there a water flow through the radiator?
This will sound crazy, but neither radiator fan works. HOWEVER, as there is no flow through the radiator (lower radiator hose and bottom driver’s quarter of the radiator are COLD), my first concern is getting flow through the radiator and then I’ll worry about the radiator fans.
What is the job of a radiator fan?
The radiator’s job is to keep the coolant cool so that when it returns back into the engine, it is able to absorb more heat. A radiator fan is thus used to keep the temperature of the coolant in check. Thus, it has an important job.
What to do when your water pump is not circulating coolant?
When you don’t feel the surge of coolant, squeeze the upper radiator hose again, and while an assistant depresses the accelerator to increase engine speed, release the radiator hose. If you still don’t feel the surge of coolant through the upper radiator hose, most likely coolant is not circulating.
Why is there no flow through the cooling system?
It overheats, and there doesn’t appear to be flow through the cooling system. The upper radiator hose is extremely hot, the lower radiator hose is cold. The thermostat has been replaced 3 times now. They have all been put in boiling water, and they all opened.

Where does the name coolant flow radiator come from?
However the range for your thermostat depends on the type of your engine, load requirements, weather, and other variables. Most thermostats are the “pellet” type; the name comes from the wax pellet that expands as the engine coolant warms. The pellet’s expansion forces the valve open.

Why does a coolant flow radiator slow down an engine?
If the air coming through the radiator is cool, the opposite happens; the coil spring contracts, the oil leaves the fluid coupling and the fan slows. Slowing the fan when it is not needed reduces fuel consumption, makes less noise and saves engine power.
