Very much
how much to fix it.. where is the coolant sensor on a 2007 ford fusion
which one? low coolant or ECT?
2 to 3 volts.
An engine coolant temperature sensor will usually need to be replaced when it is drawing too much or too little voltage. The sensor may also have a bad ground connection.
Check low coolant sensor. Aslo, I have found that the sensor requires the "slipperiness" of a proper coolant/water mix...too much water and the sensor will stick. ==New answer headline== Also make sure you are using the right coolant. On my 97, the light will only go off if i use Dex-cool. anything else and it will stay on.
The low coolant sending unit is integral to the coolant reservoir. I just called two dealers, they were both $117 for the reservoir(!!). Before replacing, try cleaning the contacts on the connector, and also try cleaning the sensor in the reservoir with a long bursh before spending that much money.
less than £10.00
you may have a bad sensor or lose sensor check to see if the wireing is rubbing on anything i belive if you have too much water in relation to antifreeze then the light wll come on, have your coolant tested at a service station to make sure you are using the correct ratio.
it is low coolant temperature, could be the thermostat could be the sensor for coolant temperature.
A Toyota Camry can hold 6.7 quarts of coolant when it is bone dry. You should add the needed liquid so that it reads at full at all times.
I assume you has an s series Saturn If so you are in luck because that code is caused by the coolant sensor cracking 90% of the time Replace the sensor and the harness (if corroded) and you'll be good to go
Coolant to the machine tool is used by the pump again. Coolant level in the reservoir capacity is dependent on the device. The amount may not exceed the 30 liters or 10 gallons.
