is the coolant temperature sensor giving a correct reading to the computer? Is the fan getting power?
That is the temperature at which the cooling fans are coming on, this is common for newer cars. It is not a problem, and should not cause you concern.
It depends on the year, make and model plus the outside temperature but between 37 to 48 degrees...
Because it's leaking somewhere. Other than lines in the cooling system, head and intake manifold gaskets are a possibility.
If this is on a 2.7 litre engine, probably the cooling system needs to be bled. Other causes could be the thermostat, but they are very relieable. Even though the cooling system reserviour shows full, the cooling system might just need to be bled properly. Has the engine had a cooling system failure. Blown hose or leaky radiator Most common for this failure on the 2.7l engine is low coolant level. The heater core supply lines and temperature sensor sit as high as the top of the engine and when the cooling system gets low on coolant, the first thing noticed in cooler weather when you turn on the heater is no heat coming from the heater. You may also notice the temperature gauge fluctuation(moving up and down), or below normal to normal temperatures. This is all caused from low coolant level. Fill coolant tank, then properly bleed the cooling system. You can bleed the cooling system by placing a clear plastic hose on the coolant bleeder valve at the top of the engine, just left of the intake manifold. Next to it is the engine coolant temperature sensor. Place the other end of the hose in a clear container, open the valve counterclockwise and monitor the coolant flow through the tube. When the bubbles stop and coolant is clear, your system is clear of all air and full of coolant. You may need to redo this two or more times after driving a while.
Check to see if the electric cooling fans are coming on, and at the proper temperature. The air conditioning is adding heat to the engine, and your cooling system cannot remove the extra heat. This happens with some cars at idle, when the heat stays around the engine and the coolant is not circulating as quickly. Extra electric fans are installed to deal with this, but they have to be operating properly and you have to have the proper mix of antifreeze as well.
It have battery
One way to tell if you're low on coolant on a central AC unit is to feel the air coming out of the vents. If the air is warm or room temperature, it is a sign that you are low on coolant.
Low coolant level. The 2.7l v6 engine is bad about this problem, even though the coolant reserviour tank shows full. At low rpm, the coolant sensor shows low temperature and no heat coming from the heater. When you raise the rpm level, the temperature gauge will raise to operating temperature and heat comes from the heater. The coolant system has air in it and needs to be bled. To bleed the cooling system, find the coolant bleed valve located next to the coolant temperature sensor. They are in the plastic housing at the top of the engine just left of the intake manifold as you are standing in front of the car after raising the hood. Attach a clear plastic hose to the top of the coolant bleed valve. Place the other end in the coolant reserviour or some other container. Open the coolant bleed valve and monitor the air bubbles in the coolant through the plastic line until all bubbles passing through the line stop. You may be required to bleed the system several times as air is trapped in different places and moves to the top of the engine as you drive.
it is on the back of theengine with four wires coming out the connector is blue
If you have coolant mixed with air bubbles coming out, you may have a cracked head or a bad head gasket. Have a pressure test done on the cooling system to verify there is a problem.
The coolant temperature sensor on an 89 Taurus with a 3.8L V-6 is located directly above the thermostat, where the upper radiator hose connects to the engine. the sensor is positioned vertically and has 2 wires coming off of it.
