I believe you are refering to the thermal switch for the electric fan. The switch is located on the bottom tank of the radiator on the driver's side (left-hand drive), just above the drain plug. This switch is a thread-in type with two round prongs where the wires connect. To remove/replace, drain the radiator first, then using a 21 mm socket or wrench, unthreadd the switch from the radiator. There is a second switch which threads into the thermostat housing loacted on the back on the engine head. This switch is part of the emmission control system and also controls the electric fan. Before you remove or replace the radiator switch, disconnect the wire from the thermostat housing switch first, to test the rad switch and electric fan. (I had to do this job just last weekend).

at ther end of the upper radiator hose on the motor
The Thermostat is located at the low side radiator hole housing ( one end of the hole is connect from the radiator and the other end is connect to the housing
thermostat is located under radiator cap!
Follow the top radiator hose from the radiator , where it connects to the engine is where the engine thermostat is located
there are 2 large black hoses that come off of your radiator. the one located higher on the radiator (upper radiator hose) goes from your radiator to the thermostat housing. the thermostat housing is a metal tube that is bolted to the engine. the thermostat is located inside of the housing and can be accessed by removing the bolts
The thermostat on a 1989 Nissan Sentra is on the front of the motor to the left. It is just below where the valve cover meets top of the manifold. The thermostat is enclosed in the radiator hose at that location.
Probably at the engine end of the upper radiator hose
Usually in housing at engine end of top radiator hose
The thermostat on a 1989 Chevy Celebrity is located under the water outlet fitting. Follow the upper radiator hose, it will end at the water outlet.
Thermostat? or radiator? Greg
Next to the radiator on the drivers side, in front of the battery.
maybe check the thermostat.
By the thermostat housing - follow upper radiator hose back to block.
Should be in a removable housing at the engine end of the upper radiator hose
in the waterneck the piece that the upper radiator hose connects to the intake manifold
It is under the housing where the upper radiator hose attaches to the engine.
Thermostat, low coolant, inoperative radiator fan, failed water pump, plugged radiator, head gasket.
follow the top radiator hose from the radiator to the manifold I believe it is there in a housing that attaches to rear end of top radiator hose
Follow the top radiator hose back to the engine. The radiator hose connects to a housing that is bolted to the intake manifold. Remove the radiator hose the remove the two bolts that hold down the housing and the thermostat is right there.
Where the big radiator hose connects to the front of the block.
thermo stat is in housing underneath the radiator cap attached to the head
On the engine end of the upper radiator hose is the location.
Thermostat messed up, Oil needs to be changed, no antifreeze in the radiator, radiator fan is not working properly
Try to determine the origination of leak i.e. radiator, hose, thermostat housing etc. Try to determine the origination of leak i.e. radiator, hose, thermostat housing etc.
Follow the upper radiator hose to the engine. It's in the housing on the engine.
